SICK – dual focus in a uniform presence

Dear Readers,

For many companies in the factory automation business, Spring 2004 is againdominated by the Hanover Trade Fair. This year, however, sees the integration ofInterkama – in its time, one of the world’s leading process automation fairs. ForSICK, this results in a new dual focus: in addition to the “Hanover-proven” prod-ucts and system solutions for automation, safety and identification technology,we now add the analysis and process instrumentation of the newly foundedGroup subsidiary SICK MAIHAK. The SICK Group – thanks to its innovative prod-ucts and consistent customer orientation – is a global player in both areas ofbusiness. This will be made clear in Hanover. We look forward to meeting ourbusiness partners from all over the world who, for their part, expect a lot fromtheir visit to SICK’s stand. Numerous new products – above all a completely newgeneration of photoelectric switches, and innovative analytical, environmentaland process sensors – form the framework for interesting and intensivediscussion.

We look forward to your visit, to your ideas and to your comments. We wish youall the best until then – and hopefully a good read in this, the latest issue of ourcustomer magazine SICK insight.

But the stock of cheese grad-ually comes runs low, after a long periodof peace and quiet. How do the inhabi-tants cope with this new situation? Whereis the new cheese – who is going to makethe effort to find it? Read more about theadventure on Page 46.

Co-operative production, networkedbus systems, safety sensors for thethird dimension, distributed safety intel-ligence – Gerhard Mutter, DepartmentManager in SICK’s Safety Systems Divi-sion, mentioned many visions during aninterview with IEE, the specialist jour-nal. No wonder, then, that it did nottake long for there to be a noticeable re-action.

During a conversation with IEE Edi-tor-in-Chief Stefan Kuppinger, GerhardMutter risked describing his view ofevents on the technological and stand-ardisation horizon – and beyond. The in-

“The Good Thief” with Nick Nolte

The LMS conquers the silver screen The LMS Laser Measurement Sys-

tem has, for the first time, appeared onthe cinema screen – in the film “TheGood Thief”. The LMS’s nude support-ing role took place at a museum inMonte Carlo.

Broke again, Bob Montagnet (NickNolte) is preparing a major coup. Buthe is not going to try stealing the casi-no’s takings – he is eyeing up theworks of the great masters in theMonte Carlo Museum. Bad luck for himthat he runs up against the LMS in anude supporting role: “nude” becausethe LMS is stripped of its front screen,and “supporting” because the rotationof the laser deflector mirror is only fea-tured for a few seconds. Can the LMSstop Bob Montagnet? Nick Nolte knowsthe answer – and all those who have al-ready seen the film. INFO 101

>> Rotative sensors, optoelectronicdistance measurement systems, andlinear, magnet-based absolute lengthdetection solutions are the most com-monly used continuous processes fordistance measurement, and the posi-tion determination of rail-borne vehi-cles that is derived from it. Whetherhighly dynamic control, non-contactmeasurement, or suitability for largeoutdoor plants – each functional princi-ple has its specific advantages.

Major advantages for longmeasurement paths in harshenvironmentsThe strengths of the Pomux KH 53come to the fore wherever positionsmust be determined over long dis-tances with uneven measurementpaths (e.g. rails) and under harsh envi-ronmental conditions, such as fog, rainor snow. With this robust system, asensor component determines the ab-solute position from reference marks

In use throughout EuropeThe Pomux KH 53 is used at numeroushandling plants worldwide, for examplein the Netherlands, Great Britain,Japan, France and at the seaport ofHamburg-Altenwerder – the world’s firstfully automatic container terminal of itstype.

Noreference run is required when theplant is started thanks to continuous“real” absolute position determination.A high level of functional reliability isachieved during operation. The operat-ing temperature range is between–20 °C and +85 °C. Moreover, thefunctional principle is highly reliableeven under poor ambient conditions,e.g. ice, rain or snow, or if there iscontamination.

Given the extent to which automation at ports and container ter-minals is progressing, the Pomux KH 53 path measurement sys-tem from SICK-STEGMANN can look forward to many moreinteresting areas of operation, e.g. for positioning gantry cranes.

S 3000 safety laser scanners on printing machines at Axel Springer AG 07Applications

S 3000 improves operational readinessat Axel Springer Verlag

>> “In October 2003, the S 3000 re-placed three fixed systems that hadmonitored the transfer area of the print-ing cylinders”, reported Ottmar Bach-mann, Manager of Electrical Engineer-ing at Axel Springer AG. Oliver Muth, anengineer at SICK distributor Püttmann,who suggested the solution, added:“The main advantages in this applica-tion were the protective field switchingintegrated in the S 3000, its range of7 m, and the many years’ positive ex-perience already gained with numerousPLS units at the plant.”

The handling of printing cylinders is running much smoother thanbefore at Axel Springer AG in Darmstadt. This is because of the S 3000 Advanced safety laser scanners that monitor the workareas of two gantry cranes.

Improved operational processThe handling zone of the gantry cranesis monitored without contact, as thisarea is both access and passageway tothe printing machines behind it. “Untilnow, the plant had to be reactivated atthe terminal after anyone had crossedone of the safety areas”, explainedOttmar Bachmann. “But this was oftenforgotten in the hectic of everyday busi-ness, so that the plant was at a stand-still and the supply or removal of print-ing machine cylinders often came to ahalt.” This problem has been solved

with the S 3000: the gantry cranecomes to a stop if the device detects aperson. The S 3000 detects when he orshe moves out of the monitored areaand the crane is automatically restart-ed. This solution is possible because ofthe scanners’ enhanced 7 m range,which now allows the handling area tobe monitored over its entire width.

Can do more and costs lessThis application underlines that theS 3000 sets a new technological stan-dard. Improved performance data andintegrated functions offer users moreapplication opportunities and also costless. “Lower installation and wiringcosts, less space required, and mini-mum safety system maintenance costscompared to before speak for them-selves”, Ottmar Bachmann summedup.

OD Hi displacement sensors control automatic assembly at Bosch08 Applications

OD Hi displacement sensors control assembly of fuel injection pumps

Positioning with 0.125 mm accuracy

>> The orientation of the axis of a motoror, more precisely, its rotor, must be de-tected with an accuracy of 0.125 mm on

two production lines. Otherwise, precisegripping by a robot, and perfect insertioninto a housing, would be impossible. The

rotor, however, has a diameter of just 4mm – and a glossy surface. High de-mands then – reliably met by the OD Hi.

Position detection at a 90° angleA Safety Class 2 laser light source, a sin-gle-device design, sensor start via a set-up menu, scanning distances that canbe taught-in, and digital (and thus highlyprecise) signal processing are just someof the advantages of the OD Hi. Whatwas particularly important for this appli-cation, however, was the CMOS detec-tion element integrated in the displace-ment sensor, which meant that the re-flections from the rotor did not impair thereliability and precision of the measure-ments. On each line, two OD Hi unitslook down upon the rotor at an angle of90°. The digital outputs are taught-in insuch a way that they only switch wheneach measurement distance is withinthe tolerance of 0.125 mm. The robot’sgripper can only place the motor in thehousing when both OD Hi units provide asignal to the PLC.

A team-led solution“An employee on the production line ini-tiated the solution”, reported ThomasBrehm from Bosch. “This concept wasthen implemented together with SICK.”Successfully implemented – becausedamage to the housings during insertionof the rotors are now a thing of the past.

The OD Hi displacement sensor – the high-tech solution for scan-ning and measurement in the µ-range – makes use of its entireperformance capability at Bosch in Nuremberg. It controls, withmaximum precision, the automatic assembly of throttle valves forthe air management of fuel injection pumps for cars.

>> Ermaksan, based in Bursa, is notjust the leading press producer inTurkey – an export quota of 80% showsthat it is also at home on the worldmarket. Supported by SICK distributorOnur Muhendislik, the previously exten-sive range of safety equipment usedhas been reduced to the SICK safetystandard that is valid worldwide.

The C 4000 Advanced as auniversal solutionWhether trimming presses, hydraulicpresses, or other types of machine –the C 4000 Advanced, with a protectivefield height of 900 mm and a resolutionof 14 mm, is the universal solution foralmost all safeguarding tasks. Goneare the times when expensive storageof a variety of systems from differentproducers was necessary. Spare partsproblems are just as passé as difficul-ties obtaining service and repair forolder or even new safety systems onthe machines that are employedaround the world. Ermaksan customersnow benefit, for example, from the pro-

grammability of the C 4000. Blanking,resolution and other configuration as-pects can be defined via user-friendlysoftware. Help functions, informationon function parameters (e.g. responsetimes), or easy-to-understand errormessages save a lot of time, particu-larly during commissioning. Compre-hensive documentation on the C 4000,and the distributor’s expertise, cut thetime necessary for problem-solving. Fi-nally, producers and users of pressesprofit equally from SICK’s worldwidepresence – system components andspecialist knowledge are both availablelocally if anything goes wrong.

Beer and logistics from Interbrew – both can be a real pleasure

No dry times at Interbrew

>> The Belgian Interbrew Group is con-sidered “the world‘s local brewer”. Thecompany is now represented in 120countries and produces 102 millionhectolitres of beer annually. Its suc-cess is based on an extremely widerange of top-class brand leaders, suchas Stella Artois, Beck‘s or Hoegarden,as well as numerous beers typical oftheir regions.

Beer here – systematicallyInterbrew has introduced a plant-widestorage administration system thatmonitors all movements of goods be-tween three of the four Belgian sub-sidiaries. All goods flows are coupledto order processing and invoicing pro-grams, as well as production and over-all planning. This is an information lo-gistics principle based on two types ofbar codes: the serial shipping contain-er code (SSCC) and the EAN bar code.The consistently reliable identificationof these codes, wherever they are lo-

cated, is the task of CLV 450 bar-codescanners mounted on fork-lift trucks.

The scanners miss nothingThis complete solution was realised bysystem integrator IDLink. Each fork-liftvehicle has a pair of CLV units mountedon its fork (accommodated in a protec-tive housing). The driver confirms thedetected code as soon as one or morepallets of beer have been picked up. Adata box initially transfers this read in-formation to the fork-lift terminal, be-fore it is transmitted to the storage ad-ministration system by data radio.

Laser scanners for every situationInterbrew Belgium opted for SICK scan-ners because they were the only onesthat met every aspect of the perform-ance specifications and operating re-quirements without exception. The de-vices are extremely compact, efficient,easy to program, and operationally reli-

Checking filling heights withultrasound sensors

Detection from asafe distance >> The days of dirty and inoperativesensors at the tarpaulin and foil pro-ducer Kirson GmbH, Industrial Rein-forcements, are over. The filling level ofa vat of glue can now be monitoredfrom a safe distance thanks to aUM 30 ultrasound sensor.

Nets and fibrous webs are bondedtogether with the glue from the vat, soit is important to maintain a sufficientfilling height. Monitoring with a capaci-tive sensor proved unreliable: becauseof its low range the device had to be in-stalled near the surface of the glue.The consequences – frequent splash-ing, spurious switching and sensor re-placement.

Better from a distanceThese problems are a thing of the pastwith the UM 30 ultrasonic sensor.Mounted at a distance of about120 mm from the glue, it is outside thepotential contamination range. Its reli-able operation since installation nowopens up more areas of application forthe UM 30 at Kirson, including monitor-ing filling levels in dirty water contain-ers about 4 m deep, whose floatingswitches block from time to time.

Mobile volume determination

Measurement on wheels

>> It all started when a branch of thefreight forwarder Spedition Dachserwanted to detect loaded Europalletsmore quickly and precisely without hav-ing to give up the possibility of using a va-riety of detection sites. Moreover, thevolume data was to be fed into the com-puter system in effect simultaneouslywith the measurement and the palletmaster set assigned via the bar code.

Always in the right positionwith the “Volumobile”The mobile volume measurement stationfrom WP consists of a welded steel con-struction on rollers, with the scanners ofthe VMS 200 attached to a traversingbeam. A linear axis with a three-phaseasynchronous motor and integrated plan-etary gear provides the relative move-ment of the station to the pallet duringrunning measurement. The electricalcontrol, a PC with printer, and a hand-held scanner for bar-code detection areon a separate wagon. Common industri-

There are many reasons for a mobile determination of the vol-umes of, say, pallets: limited space, better utilisation rates, or de-centralised detection stations. WP Anlagen- und Systemtechnik,in Bremen, has taken up this idea and developed just such a sys-tem. The VMS 200 from SICK is the central component.

al multifunctional plugs provide the pow-er supply and data contact to the net-work. Whether incoming or outgoinggoods areas, the commissioning prepa-ration area or some other location –measurements are carried out whereverthere is something to be measured!“This flexibility was of decisive impor-tance, enabling Dachser to report theamortisation of the measurement sta-tion after just three months”, says WillyPaul, Managing Director of WP Anlagenund Systemtechnik.

How to carry out mobile measurements The elevating platform with the pallet isdriven under the measurement station.The bar code is scanned with a hand-held scanner and the volume measure-ment started. “The width and height aremeasured by the volume scanners, thelength is determined from the relativemovement”, explained Willy Paul. “All in-formation is then prepared in a form thatcan be read in ASCII or Excel, as de-sired.” The new process offers signifi-cant advantages over the tape measureand paper method: rapid measurementand data capture, precision, consistentdata, availability throughout a number ofdepartments, contemporaneousness,plausibility tests, and early error detec-tion. “And the system can also be sup-plemented by a weighing device so that aweight value can be integrated simulta-neously”, said Willy Paul, adding a fur-ther argument for measurement onwheels.

A spot of paint – yes or no? This decision is made by the ICS 100colour sensor during the production of catalytic converters atFAURECIA Abgastechnik in Trabitz, Germany. Its special feature:despite the perforated honeycomb structure on which the spot islocated, the sensor can detect it with a reliability that has hith-erto proved impossible.

order to ensure that the order in whichthey are inserted is correct (first thenarrower, then the wider), the catalystwith the smallest diameter has a white

spot of paint on its surface. This sur-face, however, has a perforated honey-comb structure so the spot does notappear as a homogeneous area. Thishas always proved problematic for sen-sor solutions – until the ICS 100 ar-rived.

Decisive criterion: the minimum pixel sumThe ICS 100 camera sensor is mount-ed 70 mm from the catalyst and in-spects a field of about 20 x 20 cm2 onits surface, within which the spot ofpaint is expected. While this has a dia-meter of approximately 40 mm, thepaint is mainly located on the latticethat forms the honeycomb pattern.Moreover, the paint may well sufferwear during transport. Given these con-ditions, the minimum pixel sumprocess proved to be the right solution.The sensor reports the presence of thespot of paint – without being deceivedby the relatively large dark hole in thebackground – from a programmedthreshold involving only a little light-im-age information. Even if the spot ofpaint has been damaged by friction,there is always enough of the white sur-face left to allow reliable switching.

Enthusiastic about the solution“At last, a functioning and reliable so-lution after so many trials with othersensors”, Markus Götz from FAURECIAenthuses about the ICS 100. “And in-stallation and commissioning only tooka few minutes with simple program-ming via the VSC 100 set-up tool.” Nowonder that the ICS 100 is gettingmore applications in its “sights” atFAURECIA.

Safeguarding a giant AGV with cylindrical safety photoelectric switches at Indumat 15Applications

2Lateral safety for giant AGV using the VS/VE 18

So that nothing gets in the way of lateral movement

The use of SICK safety scanners for the non-contact safeguardingof drive paths before and behind automated guided vehicles is thetechnical norm. With the VS/VE 18 cylindrical safety photoelec-tric switch, sensors are now also available for monitoring thesides of vehicles economically, thanks to their easy mounting.

>> 3.7 m wide and 13 m long – theseare the impressive dimensions of anAGV specially produced at Indumat inReutlingen, Germany. Its load: aircrafttails. While the main direction of move-ment and reverse motion are moni-tored with safety laser scanners, an al-ternative was sought to mounting 13-metre-long mechanical switching stripson the vehicle sides.

Detecting ships on the Panama Canal with LMS Laser Measurement Systems16 Applications

7Panama canal equipped with 74 LMS Laser Measurement Systems

Quicker lock passage, fewer accidents

>> About 14,000 ships, with a maxi-mum length of 294.1 m, pass throughthe Panama Canal each year. Theyhave to negotiate three lock systems(Miraflores, Pedro Miquel and Gatún)as they travel the 80 km “overland”.Thus, theoretically, there is a shipevery two kilometres. This involvesround-the-clock operation of the locks –ships enter or leave them almost with-out pause. In view of the ever-increas-ing density of traffic, after the USA ced-ed control of the canal to Panama in2000 the Panamanian authorities soondecided that modernisation was re-quired.

Reliable boat detection requiredTwo of the main aims were: preventingcollisions between ships and locks,and optimisation of the lock process it-self. This, however, depended on find-ing a way to reliably detect ships in thelock areas. The infrared sensors thatused to be employed couldn’t meetthese demands – for a variety of con-structional and process-related rea-sons. The project reached SICK Spainvia Doger Technology, who had provid-ed equipment for the Panama Canalover many years. “We, in turn, remem-bered that our colleagues at SICK

fractive limit with blank objects. AlphaSweden decided to use the contrastscanner in a somewhat unusual way:scanning against a reflector in the back-ground provides a considerably longerrange and a more stable measurement.

Rapid teach-in for rapid cyclesDuring installation, the KT 3 is first setfor differentiation of the two materialsusing a simple teach-in function, where-by the “blankness” of the material is al-so measured. This further increases thereliability of the detection signal. The Al-pha Sweden machine produces about15,000 DVDs a day. With its switchingfrequency of 10 kHz, the KT 3 is ideallyequipped for this high-speed applica-tion.

>> Alpha Sweden is a well-known pro-ducer of machines for producing CDsand DVDs. A sensor was sought for au-tomatic differentiation between the twosubstrates to be bonded in a machinefor producing recordable DVD blanks.While the dummy substrate is transpar-ent, the information substrate has aweak violet colour. Alpha Sweden usesthe KT 3 contrast scanner from SICK toensure that it really is two differencesubstrates that are being bonded to-gether. “We chose the KT 3 because itcan reliably differentiate between trans-parent and semi-transparent materials.This task alone is difficult enough for anoptoelectronic sensor, but it is madeeven harder by the low disk thickness of0.6 mm”, explained Tord Karlsson, re-sponsible for the production of the DVD-R machine at Alpha Sweden.

Installation during runninglock operationUp to 28 people were involved in plan-ning and completing the project over aperiod of 8 months. After an initial pro-totype installation, all three lock sys-tems were equipped one after another.“We had to be both quick and flexible,as there were sometimes only a fewminutes available for carrying out theindividual mounting steps between theindividual ship passages. Then onehad to wait for the next ship to gothrough”, remembers Project ManagerRoger Flores. “It was an enormous re-lief when everything was finally in-stalled, the software was running andthe control system and display was op-erating as desired.” The safety of thelock gates and the ships has been sig-nificantly improved – a performance forwhich the clients were pleased to raisetheir Panama hats.

C 4000 Micro in an IP 67 housing: hygienic and productive

Safety for schnitzel presses

10% more throughput and 100% personnel protection – these ad-vantages are provided by the C 4000 Micro safety light grids onthe meat-shaping presses of Swiss producer Hoegger AG. Theiruse is made possible by the IP 67 housing that protects the safe-ty equipment from damage by detergents and cleaning process-es.

>> Meat-shaping presses are used inthe food industry for two reasons: tostandardise the weight of fresh meat(e.g. schnitzels), and to press andshape smoked meat such as bacon orham products. In the process, hydrauliccylinders operate in all three axes in thepress chamber. Up to now, Hoegger hasused movable protective shutters, criti-cised as being time-consuming andcounterproductive, to protect machineoperators or maintenance personnelwhen accessing the machine.

The washable alternativeWhilst use of electro-sensitive protectiveequipment has, up to now, failed tomeet the hygienic demands posed bythe machine’s cleaning process, theproblem has been solved with theC 4000 Micro safety light grid in itsIP 67 housing. The protective housing isa PMMA acrylic tube with V4A stainlesssteel end caps. It has a compact designensuring that no inaccessible clumps ofdirt can accumulate. A pressure equal-isation membrane integrated in the end

caps prevents the ingress of dampnessand ensures a continuous condensa-tion-free view. Cables enter via industri-ally proven PG threaded connectiontechnology.

Positive ECOLAB material resistance tests with P3 detergentsThe material resistance of the IP 67housing series and the cable materialshas been positively evaluated in materi-al resistance tests by Ecolab (Henkel)for P3 detergents (P3-topax 56, P3-topax 66, P3-topax 91, P3-topactive200, P3-topactive DES). This low-pres-sure foaming process (COP cleaningand disinfection) corresponds to the de-mands of the food processing industryand is recommended.

Trade Association confirmsuse on meat processing machinesThe introduction of the IP 67 housingwith the C 4000 Micro for this meat pro-cessing machine has been followed bythe Trade Association, which has ap-proved it for this use. At the same time,the new safety technology has led to anincrease of about 10% in throughputthanks to simplified machine operation.

Direct connection of LMS Laser Measurement Systems to S7

Ready-to-use solution from TOC>> Bremen-based consulting engineersTOC have created a ready-to-use sys-tem for connecting Laser MeasurementSystems to S7 control assembliesfrom Siemens. Performance-orientedPLC types take differing levels of objectmeasurement complexity into account.

Integration of the LMS 200 is car-ried out with an S7 PLC and a Siemenscommunication assembly. Measure-ment values are read into the PLC viathe point-to-point connection betweenthe S7 and the LMS, and configurationparameters are transmitted from thePLC to the measurement system.

Measurement data can be evaluat-ed in the PLC: an S7-300 is suitable forless intricate uses, while the S7-400 isthe ideal solution for more complexapplications. In addition, evaluation isalso possible on a visualisation PC(WinCC) which, if appropriately equipp-ed, can also parameterise the lasermeasurement system and transmit re-quests for measurements.

L 400 – the clever solution for monitoring safety doors

Seven in one go

>> The mounting, installation and inte-gration of the classic solution withsafety switches involves several hoursof intensive work, particularly whenthere are numerous doors. Which iswhy the customer requires a time-sav-ing and reasonably priced solution.One device instead of seven, onehour’s mounting instead of the fourused up to now – the new solutionbrings about a lot of savings – and notjust on safety equipment.

Compact housing provideseasy integrationThe L 400 is used for safeguarding

hazardous areas and access. As anEN 61496 Type 4 device it is in thehighest possible safety category. Theelectronic signal preparation and op-tics units are both accommodated inthe cylindrical M18 housing of thetransmitter and receiver. The lightbeam is deflected by mirrors on twocorners so that the vertical cartoningmachine can be monitored from threesides. Evaluation takes place in theUE 401 safety evaluation device. If thelight path of the L 400 is interrupted bythe opening of a protective door, theevaluation device generates a signal tothe control system to switch off thepackaging machine.

User-friendly safetyFurthermore, the UE 401 offers usercomfort and supplementary integratedfunctions such as external device mon-itoring and restart interlock. ColourLEDs provide in-situ operating state in-formation. The 7-segment display onthe evaluation device allows rapid diag-noses by visibly indicating devicestates and faults.


Instead of requiring lots of switches, the seven doors of a verticalcartoning machine are now monitored by just a single system.The cylindrical L 400 safety photoelectric switch keeps an eye oneverything.

Maximum accuracy with four measurement paths: the FLOWSIC 600

Ultrasonic gas throughflow measurement

>> Ultrasonic gas counters have longbeen used in the area of natural gas ex-traction and transport. The extremely ex-pensive design of these devices, atypicalin process technology, and the produc-ers’ concentration on large cross-sec-tions have up to now made this technol-ogy somewhat unattractive for use in thechemical and petrochemical industries.

A process-oriented design: the FLOWSIC 600All this has been changed by theFLOWSIC 600 ultrasonic compact gascounter. In this device, the ultrasonicsensors and their connections are com-pletely integrated in the measurementrecorder, the electronics are accommo-dated in a small standard housing, andthe mounting length has been standard-ised to three times the nominal diame-ter. Moreover, the throughflow measure-ment device meets the usual explosionprotection requirements found in theprocess industry, and supplies the cus-tomary types of signals, e.g. 4-20mA,HART or Profibus.

Optimum results through fourmeasurement pathsThe FLOWSIC 600 achieves optimum re-sults and improved operational reliabilityas a result of utilising several measure-ment paths. In this way it can minimiseerrors caused by the flow profile. Theconstruction of the measurementrecorder allows the number of measure-ment paths, and thus accuracy, to bescaled to meet the customer’s needs.While two paths are usually sufficient formeasurement in the process, regula-tions dictate that four paths are used ifthroughflows are to be determined withmaximum accuracy for internal companyinvoicing. The same applies for meas-urement locations where calibratedthroughflow measurement is legally re-quired.

New generation of chips opens up undreamed-of opportunities

Greater efficiency and intelligence for pho toeleA newly developed sensor chip is on the point of revolutionisingthe world of automation technology. The first device with the newchip technology, the WT 18-3 photoelectric proximity switch, willbe presented at the Hanover Trade Fair for the first time. SICK in-sight spoke with Wilhelm Schürmann, the responsible manager inthe Product Management Department, about the advantages ofthe new technology.

SICK insight: Why is the time now ripefor a new technological trend that issupposed to set new standards?Wilhelm Schürmann: The time is al-ways ripe for new ideas – and thesearch for new standards has alwaysbeen our motor for innovations. In the80s, with the development of the firstSICK ASICs (application-specific inte-grated circuits) in photoelectric switch-es, SICK laid the foundation for contin-ued success and market leadership inworldwide competition. The early in-vestment in applications which were,up to then, almost inconceivable wasthe trigger for continuous and consis-tent further developments in this area.While even well-known competitorswere still hesitant to risk the switch toASIC technology until well into the late90s, SICK was then already using thethird generation of its special semi-con-ductors. SICK insight: Why are ASICs still rele-vant today?

Wilhelm Schürmann: The use of ASICsis now a matter of course. There are avariety of reasons for using these inte-grated switching circuits in photoelec-tric switches. On the one hand, the mar-ket’s demand for miniaturisation playsa major role, and then there are alsocost and mass-production considera-tions. Simultaneously, however, generaldemands in industry have also in-creased sharply and are continuing todo so. In addition to the increased po-tential for interference in the area ofEMC (e.g. because of mobile tele-phones, frequency converters, or otherelectromagnetic sources), greater de-mands are made on the optical side.Light beams from high and low frequen-cy illumination, other sensors, or warn-ing lamps and flashlights tax functional-ity just as much as chemical, mechani-cal or temperature effects. Theintroduction of chip technology allowedus to set new standards in photoelec-tric switch design. Those of note in-

clude high switching frequencies of upto 10 kHz, short response times, longscanning distances or ranges, and pre-cise switching behaviour and repeata-bility. At the same time, the further de-velopments in ASICs ensured that am-bient temperatures of -40 °C to +60 °C,maximum immunity to impacts and vi-brations, almost complete immunity toambient light effects of all types, andelectromagnetic compatibility are nowno longer problematic.SICK insight: What is special about thenew chip technology as used, for exam-ple, in the WT 18-3 photoelectric prox-imity switch?Wilhelm Schürmann: Another mile-stone has been achieved with the intro-duction of a new ASIC specially for pho-toelectric proximity switches with ad-justable background and foregroundsuppression. Photoelectric proximityswitches with this functionality have upto now required optical and mechanicalregulation. In particular, the demand forwide adjustment ranges, high precision,very good black/white shift, and goodadjustability and stability could only beachieved with good optics, a special re-ceiver element, and an adjustable opti-cal or mirror unit. While good optics re-main an indispensable quality feature,the new chip generation replaces theadjustable mechanics with a new typeof receiver array. Whereas maximumscanner precision could, in the past, on-ly be achieved with a mechanical ele-ment in the mirror, it is now possibleelectronically. The evaluation chip off-sets the signals and allows fine adjust-ment in several thousand steps.

r pho toelectric proximity switchesWilhelm Schürmann: A clear answer toall these points: yes! The introductionof this new chip technology not only im-proves the desired efficiency of photo-electric proximity switches, but also al-lows the realisation of a communica-tion capability right down to the level ofstandard sensors. While up to now on-ly high-quality and more complex sen-sors or actuators have offered a directfieldbus connection, with the integra-tion of the new ASIC SICK has now cre-ated, for the first time, a fieldbus-en-abled generation of photoelectricswitches. Combined with a special con-nection module for fieldbus systemssuch as Profibus, a standard sensorbecomes an intelligent sensor. Theuser is thus in a position to read in andout offset performance data, interfer-ence effects, or parameterisation data.This communication capability offersthe user far-reaching possibilities forremote sensor diagnosis, maintenanceand setup. If a sensor needs replace-ment, the new sensor can be suppliedwith stored data and setup via a pa-

rameter download. No qualified mainte-nance personnel are necessary forthis; the mean time to repair is consid-erably reduced. Furthermore, the chipallows users to visualise their applica-tion, allowing rapid and optimised sen-sor setup. Plant availability is furtherimproved with the help of this new tech-nological opportunity, and downtimesare reduced.SICK insight: With these features andadvantages, the chip technology of theWT 18-3 will be one of the highlights atthe Hanover Trade Fair. Thank you forthis conversation.

SICK insight: What advantages doesthis offer users?Wilhelm Schürmann: This further de-velopment offers users a number of im-provements. Object detection is nowconsiderably more accurate. Longscanning distances can be significantlybetter adjusted – and this with either arotating element, or single-button ordouble-button teach-in. And theblack/white shift has been optimised.This chip technology also takes theharsh industrial environment into ac-count by suppressing active and pas-sive sources of interference in thebackground, and with stable adjust-ment behaviour even when subjectedto impacts and vibrations. And whenthings get particularly demanding: ad-justable digital hysteresis, analogueoutput and supplementary sensor intel-ligence are also available.SICK insight: How does this intelli-gence express itself? Can the sensorlearn? Can it ask and answer ques-tions? Does it have an expanded hori-zon?

>> Solving demanding automation ap-plications means being able to handlerapid process speeds and demonstratehigh availability under extraordinary op-erating conditions. And it is preciselythis for which the new W 18-3 has beendeveloped. The application experiencegained from the forerunner families

has been implemented in powerful sys-tem technology throughout the series.Thus features such as further im-proved immunity to both ambient lightand mutual interference are as stan-dard for this device as its optimisedhousing with reinforced mountingholes, its reader-friendly all-round LED,

The best has been improved, and packed in a modern design – thenew W 18-3 series of photoelectric switches sets a new standardin accuracy and operating properties. The WT 18-3 photoelectricproximity switch is the technological highlight of the series: inte-gration of the latest SICK chip technology offers the opportunityof, for the first time, setting scanning distances electronicallywith background suppression of a hitherto impossible precision.

DT 60 and DL 60

New scanners for analogue distance measurement

>> Analogue distance sensors areused in storage and conveyor technolo-gy, e.g. for determining distances toautomated guided vehicles or to con-veyor units on suspension conveyors.Further areas of use include monitoringstorage space occupancy, and filling

levels in hoppers (e.g. at automatedpharmacies). The DT 60 is used fortasks with measurement ranges of be-tween 200 and 5,300 mm, while theDL 60 reflector version is the rightchoice for position determination overlonger distances of up to 24 m.

Intelligent type key for plug &play useFor the first time, the DT 60 and DL 60allow users to directly define plug &play versions. This is made possible bythe intelligent type key integrated in thedevice order number. It offers the pos-sibility of linking the 4–20 mA analogueoutput to an individually defined meas-urement range. This provides the userwith a device that is ready for immedi-ate use, and the possibility of re-order-ing the identical device, even aftermany years, because the parameteris-ation data is included in the type num-ber of the device. The DT 60 and theDL 60 are also available as teach-inversions for those who would prefer toset their own parameters rather thanuse plug & play installation.

Whether the DT 60 or DL 60 – bothdevices are cost-effective laser solu-tions for long-range analogue positiondetermination.

Photoelectric proximity switch with state-of-the-artchip technologyThe technological highlight of the se-ries is without doubt the WT 18-3 pho-toelectric proximity switch. It is the firstdevice of its kind with chip technologythat has been specially developed forscanners. This not only provides con-siderably more precise detection re-sults – it also allows electronic settingof the scanning distance with more ac-curate background suppression. Teach-in of scanning parameters can be car-ried out with an adjustment element.As options, scanner versions are avail-

able with one-button teach-in or two-button teach-in and additional fine ad-justment. Regardless of the teach-inmode selected – chip technology andelectronic adjustment now make defini-tion of the work-points of all the scan-ners faster and more precise.

Photoelectric switches: more precise and tougherThe detection precision and adjustabil-ity (key words: smaller red-light spot) ofthe WS/WE 18-3 through-beam photo-electric switch and the WL 18-3 photo-electric reflex switch have been consid-erably improved.

No “generation gap” with the W 18-3During development of the W 18-3, agreat deal of attention was given tocompatibility with predecessor series.One-to-one mechanical and electricalintegration allows simple upgrading tothe new W 18-3 when replacing the“old” W 18-2.

>> The RE 4000 is a non-contact mon-itoring system consisting of an evalua-tion unit with sensors and actuators.The sensor’s magnetically coded reedcontacts are designed in the tried-and-tested N.O./N.C. contact combination,and thus provide the necessary redun-dancy and diversity. The coding en-sures a high level of tamper-proofing.

An evaluation unit for up to six sensorsUnlike in individual systems, up to sixsensors can be connected to the eval-uation unit of the RE 4000. And the

system has integrated manual restartand external device monitoring func-tions. In addition to the enormous po-tential for savings on relays and ca-bling, these factors also offer practicaladvantages during operation. For exam-ple, the evaluation unit shows the stateof each individual door at a central lo-cation by means of six integrated LEDs– considerably simplifying commission-ing of the system and servicing of themachine. On the output side, threesafe channels, a signal contact, and atime-delayed output offer maximumflexibility during integration in the con-trol system.

Meets the highest safety demandsThe RE 4000 is certified as Category 4according to EN 954-1. Thus the non-contact safety system can be em-ployed in potentially highly hazardousmachines.


Those who have to safeguard several doors on mechanical sepa-rating protective equipment can now save a lot of money. Up tosix doors can be centrally monitored by the new non-contactRE 4000 safety system. Relay and cabling costs are cut, whilereaping maximum safety in Category 4.

New fieldbus gateways for all 1-D and 2-D scanners from SICK

As an expansion to its modular connection concept for CLV bar-code scanners and ICR reading devices, SICK is presenting itsnew CMF 400 fieldbus gateways for Profibus-DP and DeviceNet atthe Hanover Industrial Trade Fair (HMI).

Three slots reserved in theconnection boxThree of the slots in the CDM 400 con-nection box are reserved for CMF 400fieldbus gateways. As a result, it is nolonger necessary for users to stockfieldbus-specific scanner types. In addi-

tion to the direct connection of a singlebar-code scanner, it is also possible toconnect up to 32 scanners from a CAN-Scanner network to Profibus-DP or De-viceNet.

Exploiting advantagesThe CMF makes many things a lot sim-pler for the user: configuration of thescanners, integration in a PLC, or inter-ference-free data exchange betweenthe CLV or ICR devices and the PLC. Fur-thermore, signals from photoelectricswitches, for example, can be integrat-ed via the four additional digital inputsand outputs, and the bar-code scannerscan be pulsed via the fieldbus.

>> Distance measurement systemssuch as the DME 5000 are mainlyused for determining the positions ofstorage and retrieval devices (SRDs) inautomated warehouses, and for con-trolling cranes. The sensor moves withthe mobile unit and permanently meas-ures the time-of-flight of the emittedlight impulses to the end of the drivepath and back. The electronics deter-mine the position of the SRD or cranefrom this time data, and transmit it tothe higher-ranking control system.

Three application-specifictypesAs a result of the differing require-ments, in addition to a new version

for crane applications, the DME 5000is also available in two storage-orient-ed versions. These are designed tomeet the special needs of automatedsmall parts stores or high-bay ware-houses for pallets. All systems offerhighly dynamic measurement andgreat accuracy at levels not hithertoachieved. A glance at the device dis-play provides all the importantDME 5000 information. A speciallydeveloped bracket allows particularlyuser-friendly mounting and alignment.Moreover, the DME 5000 has bothCSA and UL approvals.

Precision in any position – theDME 5000 is the right choice for alltypes of warehouse, and for integra-tion in all control systems.

The DME 5000 laser distance measurement device offersnew performance features. The new DeviceNet interface al-lows simple connection to the control systems often foundin the USA and Asia. With its enhanced range, increased to300 m, the DME 5000 can handle new applications, partic-ularly in crane positioning.

Withthe expanded output string, CLV bar-code scanners can now directly assignthe weight data to an object’s bar-codeinformation. As all data are transferred

via the bar-code scanner’s host inter-face, the serial weighing system inter-face on the PLC is now freed up for oth-er use.

More rapid service made easy

>> As a rule, the more complex a ma-chine or plant, the greater its utilisation– and the greater the costs of un-planned downtimes. Servicing, butabove all lost production, is so expen-sive that in certain industrial sectorseach minute of downtime can cost EUR10,000 or more. So it’s helpful, to saythe least, if one can find and correctthe fault quickly.

UE 48 – the safety switchingdevice for five sensor typesInstead of using a device-specific relayfor emergency stop switches, safetymats, light curtains or laser scanners,the UE 48 can be connected to all ofthese safety devices. If the worstcomes to the worst, the service techni-

cian only needs to bring one devicetype – and not all the potential possi-bilities. Replacement can then be car-ried out very quickly – with minimumplant downtime. But anyway, this onlyhappens extremely rarely – the replace-ment of a defective UE 48 is about aslikely as winning a lottery: with an oper-ating life of 10 million switching ac-tions and 1,000 switching actions perday, from a statistical point of view itwould take 28 years for a device to be-come faulty.

New series of photoelectric switches for detecting parts and webs

Forks with new “prongs”

>> Fork widths of between 2 and120 mm, and three fork depths of40 mm, 60 mm and 95 mm, make thenew WF series particularly suitable fordetecting parts on feed rails and con-veyor belts, and labels on continuousrolls; monitoring feeding on automaticmounting or processing machines; orchecking for double sheets. In the newWF series, the glass optics of thetransmitter and receiver are now only3 mm from the front edge of the metalor plastic housing, significantly improv-

ing the detection of flat objects in manymounting situations. Whether as a firstinstallation or as a replacement – thenew WF offers a variety of mounting op-portunities thanks to the arrangementof fixing holes.

More accurate than potentio-meters: keyboard setting withrapid throughputWhether the version with manual settingor with teach-in, the new WF series em-

ploys two user-friendly input buttons in-stead of the otherwise customary poten-tiometers. Manual setting can be carriedout with great precision in just a few sec-onds via the “+” and “–” buttons thanksto rapid throughput. And the switchingpoint is also quickly learnt with the 2-pointteach-in version (used, for example, toteach-in the label and the carrier materialat label dispensers). If necessary, theresolution can also be manually correctedlater via the control buttons.

The new WF fork sensors from SICKoffer a variety of interesting applicationopportunities as a result of the widerange of variants available and theirhighly accurate resolution.

With the widest range of fork sensors on the market, SICK’s newWF series sets standards with a new device design offering opti-mised optical axis location, teach-in, and considerably improvedadjustability of the switching point.

Linear measurement without linear paths

Wire-draw encoders also measure around corners

>> Elevating platforms, constructionmachines, or cranes are typical exam-ples of machines whose control sys-tems require precise positional andpath information, but which do nothave a continuous path – as a result ofarticulated or hinged mechanisms. Thenew BTF/PRF wire-draw encoders (acombination of wire-draw mechanismand encoder) provide the solution. Theyare available for measurement lengthsvarying from 2–50 m, and are thus alsosuitable for smaller machines.

Drum rotations are the measure of all thingsWith wire-draw encoders, a rust-freesteel cord is moved between the start-ing and finishing points of a measure-ment section and is wound in or out ofa drum in a single layer. The number ofdrum rotations (proportional to thelength) is counted by an encoder and

converted to a measurement signal.Even without a straight linear path thisprovides precise positional and pathdata, and thus information e.g. on theplatform height of an elevating plat-form, the position of a dredging shovel,or that of a crane’s gripper. In order toallow the device to ignore the demand-ing application conditions, these wire-draw encoders have a robust housingwith an enclosure rating of IP 64, a dirtscraper, and a fat chamber for themeasurement cord.

Available with absolute or incremental encoderDepending on the favoured method ofdetermining the number of rotations,and the linear resolution desired, userscan choose between wire-draw sys-tems with absolute or incremental en-coders. With Profibus, CANopen or De-viceNet fieldbus technologies; the SSI

interface; the absolute and HTL or TTLinterfaces of incremental wire-draw en-coders, the appropriate interface fordata transmission is available for anyparticular application.

Wide range of usesThe wide variety of types of BTF/PRFwire-draw encoders available opens upnumerous application opportunities,such as for presses, extrusion ma-chines, high-bay warehouses, theatrestages, medical technology, locks andbarrage systems, and in numerous oth-er applications and branches.

The new wire-draw encoders of the BTF/PRF series from SICK-STEGMANN provide a precise and robust solution in many situa-tions where positions are to be determined or paths measured butthe measurement section goes round a corner.

The con-tour data received are supplied to theon-board computer which comparesthem with the internally stored “map”.The vehicle’s navigation software thusdetermines its drive path. Parallel toposition detection, the S 3000 Profes-sional CMS determines whether per-sons, objects or a second FMTV are onthe drive path. If so, the speed can bereduced to a vehicle stop, if necessary,or the navigation system can find an al-ternative route.

Even the most extensive parame-ter set libraries can be administrated inthe machine control system and indi-vidually loaded onto the ICS units as aformat-based data set – increasing theflexibility of the machine’s inspectioncapacities almost infinitely.

Calibrated volumemeasurement system certified>> The VMS 520 Volume MeasurementSystem has been tested and certifiedin line with recommendation no. 129“for multidimensional measurement in-struments” of the International Organi-sation for Legal Metrology (OILM). Thusmeeting the prerequisites for systemintegrators to obtain approval of com-plete weighing and identification sys-tems from national testing authorities,such as the Physical Institute ofPhysics and Technology (PTB) in Braun-schweig.

In addition to the application soft-ware for object measurement, theVMS 520 has two sensor heads thatare installed above the conveyor sys-tem. The VMS 520 measures the realvolumes of cubic and non-cubic objectswith maximum precision – as demon-strated by the scale values confirmedby the OIML: 5 mm for height, and10 mm for length and width, at a maxi-mum conveyor speed of 2 m/s. A cali-brated complete system can now bedeveloped for courier, express andpackage logistics by combining a cali-brated weighing system with bar-codescanners – and approved by a nationaltesting authority.

A new member of the Vision family

The CVS Colour Vision Sensor is used for de-tecting colours. Unlike a colour sensor, the CVSdoes not operate in a point mode but over a de-fined area within which it counts the pixels ofthe taught-in colour. Furthermore, with three dif-ferent operating distances between 50 mm and270 mm, it offers an opportunity to scan ob-jects over longer distances.

Whether AGD, DCI or CVS – all the new camerasensors are easy to adjust, and employ stableevaluation processes, making them interestingfor both OEMs and end-customers.

lows the rapid download of a parameterset if a device is replaced – a rare oc-currence. Mounting measures have al-so been taken to simplify replacement:the attachment and mechanical instal-lation of the ICS 100 have been opti-mised in such a way that the alignmentremains intact during dismantling and

mounting – a completely new develop-ment in this class of devices.

Intelligent solutions to meetindividual tasksThe family of SICK camera sensors hasbeen expanded with three brand-newdevices. The AGD sensor specialises indetecting reflections. Have metal partsbeen polished or not? Is a layer of gluepresent? Is the recessed grip of a cos-metics bottle-top in the right position?The AGD sensor has the answer tothese questions. The second new cam-era sensor, the DCI, is principally usedfor checking presence. By counting thenumber of pixels in its search field itcan detect whether, for example, letter-ing, a label or a bottle-top is present. Apre-warning is provided if the sum ofpixels detected approaches the de-fined tolerance value, showing whetherthe pixel sum is too low or too high.

Acids, alkalis and detergents, as well as high pressures and tem-perature shocks, place extreme demands on sensors and con-nection technology in high-hygiene areas at food producers andbeverage fillers. The result: limited service lives for many sen-sors. The alternative: the sensor solution package from SICK.

The sensor package in detailIM 12, IM 18 and IM 30 type inductivesensors are used for the detection ofmetallic objects in a variety of applica-tions. These sensors’ special high-lights are the three-fold switching dis-tance and the fully encapsulated stain-less steel housing. With a reductionfactor of up to 0.9, very good detectionof stainless steel and steel objects upto 1.3 can be achieved. The distributorboxes and plugs are designed in V4A(1.4404) and all comply with an enclo-sure rating of IP 69K.

Efficient in the food sectorThe “Food & Beverages” solution ispart of a comprehensive range of sen-sors from SICK for the food and bever-ages industries. These include capaci-tive proximity sensors of the CM seriesand W 4 photoelectric switches withTeflon encapsulation, as well as photo-electric switches of the W 12 series inTeflon housings that are speciallyadapted for glass detection. Whensafety technology is required for wet ar-eas, type C 2000 and C 4000 lightgrids in IP 67 housings, for example,offer continuous protection for ma-chine operators – as shown by theiruse during Camembert production oron meat-shaping presses.

imity switch, the plug and the sensordistributor box are designed to complywith IP 69K. The materials used – V4A1.4404 stainless steel and PVC –meet the requirements for sensorsand connection technology in wet ar-eas. Long SICK sensor service livesand reliable signal transmission arethe result.

>> In wet areas at food producers andbeverage fillers, conditions are harsh-er than elsewhere: pressures of 2 -100 bar, high temperatures, acids, al-kalis and detergents have a major im-pact on some sensors and some sig-nals. On the other hand, the “Food &Beverages” sensor solution from SICKhas no weak points: the inductive prox-

The Basle Paper Mill – time travel anda lively experience in one

>> The museum, founded in 1980,with its main themes of paper, writingand printing, is accommodated in threemill buildings, parts of which date backto the 12th century. But it is not justthe historical setting that is so special,but also the opportunity for the visitorto produce their own paper using theold equipment.

Paper is more than just paperThe museum tour begins with a ragstamping machine and a spherical boil-er – both indispensable during the ear-ly days of industrial paper production.Every Wednesday, specialists producecontinuous rolls of paper in A4 widthwith the laboratory paper machine thatis also set up here. One moves on to areal paper mill from the 18th century,the nucleus of the museum. This iswhere both adults and children canmake their own paper from the fibrepulp in the visitors’ vat. Interestingfilms are shown in the video room – onpaper-making and the history of print-ing. The rest of the tour is dedicated tothe latter subject. The development ofwriting from the first guide marks andnotched tallying-up poles, through thescripts of the Middle Ages, and up tothe handwriting of modern times arevividly displayed. Early printing tech-niques from the time before Gutenbergare on show, as are details on Guten-berg’s invention of book-printing. Thenthe journey from the type foundry andmachine composition to early genera-tion office devices is described. Finally,the typesetting, printing and bookbind-ing sections present paper-related ac-tivities, some of which no longer existor are only mastered by specialists.

Theory and practice at a single site Those who have experienced the com-bination of exhibitions on the history of

technology and the functioning worksat the Basle Paper Mill know that paperis more than just the white or printedsheets that we handle or look at everyday.

The Basle Paper Mill – the Swiss Museum for Paper, Writing andPrinting at St. Alban-Tal in Basle – offers a lot worth knowing,about all aspects of paper, in an historical setting.

Safety inspections for machines and plan ts


Safety equipment inspection services42 SICK Tour

>

>> German safety at work legislation(Arbeitssicherheitsgesetz) and industri-al safety regulations (Betriebssicher-heitsverordnung) demand that an em-ployer determines, or has someone de-termine, whether equipment used is inproper order regarding safety. This notonly applies to the actual protectivesystems, but also to their installationand integration in higher-ranking con-trol levels. And it is here that one regu-larly comes across incorrectly integrat-ed safety systems. The five most com-mon reasons for this are:

p incorrect integration of safety sensors into the machine controlsystem,

p the protective equipment does notaddress all hazardous movements,

p the safety clearance to thehazardous point-of-operation is tooshort,

p despite safeguarding, thehazardous point-of-operation can beaccessed by reaching around, below or over,

p the control switch for the protectivesensors can be operated from with-in the hazardous area.

These faults are not always detectable atfirst glance. This is because of the in-creasing complexity of machines andplants and, in turn, the hazardous points-of-operation. Moreover, safety systemsare continuously undergoing further de-velopment as a result of changes in tech-nology and standards – necessitatingregular “knowledge updates”.

Assistance and quality throughSICK’s safety expertiseOur up-to-date specialist knowledge isyour advantage: it lightens the burdenof your safety responsibility while pro-ductively supplementing your qualityand safety management. The centralfactor in this is the ongoing furtherqualification of our staff in the areas ofproduct know-how, application know-ledge, the development of regulations,and safety expertise.

>> Cheese-lovers and cheese-makersamongst the (hopefully) interestedreaders can count themselves lucky.This little book is all about cheese.Cheese – a metaphor for everythingthat one desires, the be all and end allin life. Something to fight for, or withwhich one can relax.

Spencer Johnson’s “Who MovedMy Cheese?”, a very simple fable, de-scribes the different reactions to life’ssituations. The main characters aremice and little people.

But let’s begin at the beginning: thestory opens with a reunion of formerclassmates who realise during the con-versation that they are all afraid ofchange. Only one could overcome thisfear – by means of the story of themouse strategy. He tells the story tohis old comrades.

Sniff and Scurry, two mice with in-stinct, live in a maze with two intelli-gent little people, Hem and Haw. Theysearch for their favourite cheese, whichthey soon find in cheese store. Certainthat the stock will never run out, theymake themselves comfortable, be-come lazy and arrogant – at least thetwo oh-so-clever little people do. After awhile, the mice notice that the stock is

The “Mouse Strategy” for managersSuccessfully adapting to change

indeed coming to an end and depart tosearch for some new cheese. The littlepeople, however, are completely sur-prised by this new situation and proveincapable of reacting. They look forscapegoats – they believe that theyhave a right to the cheese. Meanwhile,the mice have found a new stock ofcheese. The two little people strugglewith the decision for a long time, andbecome thin and weak. Finally, Hemdecides to take action. He enters themaze without Haw, for whom this allseems much too dangerous, and aftera while actually manages to find anenormous cheese store. This time,however, he takes care, inspects thestock every day, and hopes that Hawwill also be able to find his way there.

The story ends here – and it suc-ceeds in making the school-friends seetheir life in a new light, and learn toadapt for the future.

The “Mouse Strategy” really doesstimulate one to reconsider the“cheese” in one’s life. What do I de-pend on; in what matters should I haveacted long ago but failed to do so forfear of the consequences; where do Imerely react rather than act?

In one’s professional life, in partic-ular, one must nowadays keep one’seyes and ears open with regard tochange, must take new paths, let go ofwhat is past.

Thus the book has fulfilled its purpose.Though I feel that it is a bit expensivefor the 100 or so pages in large reader-friendly print, with many extra pagesdisplaying individual banner-sized sen-tences in bold print, such as “Old cer-tainties won’t lead you to new cheese”.

Still, it is a lot cheaper, and consid-erably less dangerous, than walking onhot coals. :-))
