Determining distances is one of the most common metrologi-
cal applications in automation technology. The market sup-
plies many solutions, yet not every technology is ideal for
each application. Pepperl+Fuchs’ new distance measurement
sensor, VDM28, is setting standards in this dynamic field.
With a measuring range up to 8 m, the sensor reliably de-
tects distances in diffuse mode. The groundbreaking Pulse
Ranging Technology (PRT) measuring principle is applied.
For the first time, a red laser is used as sender. It emits
short light pulses to determine distance by measuring the
time of flight of the reflected pulses. The high visibility also

Pepperl+Fuchs focuses on innovation.
Whether inductive proximity switches or
optical distance-measuring devices – we
provide just about all operating principles in
non-contact sensors for factory automation.
We are constantly expanding this product
range to meet your automation needs even
better.
We are pleased to introduce a new member
of our family of optical distance-measuring
devices. As the technological leader in Pulse
Ranging Technology (PRT), Pepperl+Fuchs
strongly backs this procedure. We have de-
veloped our technology so that it fits into a
light barrier housing and is easy to use.
The advanced Pulse Ranging Technology al-
lows better parameters at lower cost.
It compares especially well to previous time-
of-flight solutions that are based on the prin-
ciple of phase correlation. Our measuring
method is based on the time evaluation of
extremely short but high-intensity light puls-
es. This technology is applied by sensors
that are highly insensitive to extraneous light
and remain stable at high temperatures and
in the long-term without measuring drift.
You can learn more about the new compact
VDM28 distance-measuring device in the ac-
companying article.
Here’s wishing you a pleasant and informa-
tive read of what’s new in this issue of Sens-
ing Your Needs.

VDM28 – Pinpoint measuring Pulse-laser distance measuring for universal applications
enables optimal alignment. This is an innovative combina-
tion for PRT sensors and ensures perfect performance and
convenience through the unique advantages of this technol-
ogy. In contrast to other procedures, measuring accuracy is
independent of the object surface. The measuring principle
eliminates issues such as detection of “phantom objects” or
measuring fluctuations due to ambient conditions.
The device can be operated as a standard diffuse sensor or
as a distance measurement sensor. The switching threshold
settings are entered using simple pushbutton programming
via Teach-In. Since the devices include an IO-link interface,
the digitized analog value is also displayed and the device
can be easily programmed. The graphic operator interface
VDM28 – Pinpoinng
offers more options than are available by adjusting the
switching points with Teach-In. The distance measurement
sensor can be optimally adapted to each task. This results
in a wide variety of applications throughout all branches of
automation technology.
The largest selection of sensors on the market is available
for the proven housing design of the VDM28. In addition to
the distance-measuring device, thru-beam sensors and ret-
ro-reflective sensors are also available. This housing design
thus incorporates more optical technologies than any other.

PMI360D
Angle-measuring PMI360D with signaling zones (S0-S2) and/or analog angle signal
Valves are among the
most important com-
ponents in process
technology and are
available in a huge
variety of technical
versions and sizes.
Monitoring the cor-
rect valve setting
saves resources.
Rotary drives that ap-
propriately adjust the angle of the valve flap to
the desired flow amounts are used to control the
flow of fluids and gases. The current position of
the valve flap is monitored by positional feedback
sensors. Simple, binary feedback sensors can dis-
play two positions (OPEN and CLOSE).
An angle-measuring analog system such as the
PMI360D is capable of precisely measuring the
position of the valve flap and thus allows for a
much more exact dosage of the medium.
Positional feedback sensor on rotary drives
The geometric dimensions of the PMI360D are opti-
mized for standard application in rotary drives.
The PMI family provides two different types of applica-
tion with regard to functions:
• A switching sensor provides the option of 3 taught-in
signaling zones (S0-S2). Therefore another preferred
position (e.g. valve half-open = 45°) can be retrieved
in addition to the positions OPEN and CLOSE.
• The combined switching/measuring PMI provides
the option of an exact, angle-proportionate measure-
ment of the current valve position for the higher ap-
plication type. Moreover, the OPEN and CLOSE limit
positions can be fed back to the higher-level pro-
cess-control system through two separate switching
outputs.

By connecting UHF read/write heads to the IDENT Con-trol family, logistics applications with a large sensing range are also now possible. The compact UHF handheld readers are very fast, enable a sensing range of several meters and can be connected via an M12 plug, while the passive transponders are extremely cost-effective. They are therefore ideal for intralogistics.
All common frequencies can be connected to the IDENT-
Control system in mixed mode. Standardized operating,
the universal command structure for the PLC program,
and the sturdy, EMC-proof design with metal housing
make commissioning simple and safe. The range of read/
write heads has been extended with the addition of the
UHF family of antennas. The compact UHF antenna is easy
to connect via one M12 plug and has been well-received
in the field of intralogistics. Containers and pallets can
be identified as easily as car bodies in the automotive in-
dustry. Because passive data carriers in various industry
construction types as well as in the form of labels are inex-
pensively available and because we can achieve sensing

Ideal for intralogistics
ranges up to 6 meters, this system is a real alternative to
the commonly used barcode. It features significant advan-
tages: It writes data; no direct visual contact is needed;
it is not sensitive to dirt; etc.
The clever technology of the read/write head transmits
on one frequency and the transponders respond on a free
channel in order to prevent distortion and interference.

AS-i chip are ideal for cost-
effective monitoring of small
doors and flaps. In addition
to bounce issues with large,
heavy doors, the tamper-
proof transponder systems
also facilitate multiple-door
monitoring by connecting up
to 4 reading heads to the AS-i
with one control and connec-
tion unit. Operating modes,
such as set-up and mainte-
nance, can be controlled safely using AS-i enabling switch-
es. Even the indicator lamps that signal normal mode, a
maintenance prompt, or an interruption can be directly
connected to the AS-i. For safety on all fronts.

Renewable energies are already making a considerable contribution to power production and active climate protection. Wind-power and solar plants can operate efficiently only when the internal control is optimally aligned.
Pepperl+Fuchs provides a wide range of products for monitoring the most varied processes at wind- and solar-power plants. The following list gives a few examples:
Using renewable energy
• The inductive angle-measurement system PMI360 monitors the rotating assembly at solar plants.
• Rotary encoders measure the rotational speed of the rotors/generators, the rotor blade position and azi-muth direction angle at wind-power plants.
• F99 inclination sensors monitor the inclination angles of solar panels.
• The WIS system transfers non-contact energy and data on a rotor.
Reliability in harsh ambient con-ditions is particularly important in these areas of application. Pepperl+Fuchs can draw on many years of experience in this area. The sensors have proven them-selves millions of times over.

Plant manufacturers, system integrators and component
manufacturers are faced with ever-higher standards of
functional safety due to an increase in the level of auto-
mation in machine and plant engineering. Improvements
to the functionality of conventional control systems are
required, especially the capacity to meet safety function
needs, such as in modern drive controllers. Secure rotary
encoders with functional safety have thus gained in impor-
tance. Pepperl+Fuchs GmbH responds to these needs with

The new Machine Directive 2006/42/EG
a view takes the complexity of
modern programmable electron-
ics into account. In order to ease
machine manufacturers into a
smooth transition toward the
safety requirements of the new
standards, a simple integration
of components is needed, even
in existing developments.
Pepperl+Fuchs GmbH responds to these needs with products that are
new concepts, are easily implemented, and cost-effectively integrated,
including products for high safety categories (SIL3, PLe).

The requirement for member states of the European Community to
implement the single European market directives has turned the new
Machine Directive 2006/42/EG into law. This Directive will become
binding no later than December 29, 2009. It will replace Machine Di-
rective 98/37/EG.
Article 5 (par. 1) of the Directive takes in all requirements made for the
commissioning of machines.
According to Article 5 of the new machine directive, machine manufac-
turers must meet, among other things, all safety and health-protection
requirements (Appendix I).
Within this context, listed standards such as EN ISO 13849-1 and
EN IEC 62061 (from the IEC 61508-derived sector standards for ma-
chine manufacturing) take effect. The deterministic approach of the
currently valid EN 954-1, which contrasts a corresponding system
behavior to the determined risk categories, is now complemented by
a probabilistic view of the safety functions. Moreover, the new stan-
dards EN ISO 13849-1 and EN IEC 62061 also include, among others,
the failure probabilities of the implemented components, since such

Continuity in a new type of company
Market proximity and flexibility are the most
important demands made on a forward-
looking distribution company that is part of a
globally-active organization.
In order to appropriately represent this mar-
ket proximity and flexibility within the legal
and organizational structure of a German
distributor, Pepperl+Fuchs has decided to
outsource German distribution for second
quarter of 2009 to one of its own companies –
Pepperl+Fuchs Vertrieb Deutschland GmbH.
The same German distributor will operate in
two areas of business – factory automation
and process automation. Long-standing sales
managers Rainer Niess and Jörg Schneider
will be the executive directors of the new dis-
tribution company. All contact persons will
remain as previously.
Within the newly-founded distribution com-
pany, the regional sales offices set up in 2008
in Mannheim, Friedberg, Wernau, Dortmund,
Hanover and Berlin will remain unchanged as
parts of the factory automation area. At a lo-
cal level, they will facilitate efficient commer-
cial and technical support, short trips and a
flat hierarchy.
By taking this step, Pepperl+Fuchs has cre-
ated another prerequisite for furthering its
success through innovation and proximity to
its customers.
Pepperl+Fuchs sets up a German distribution company and moves closer to its customers Hannover Messe Industrie
