Direct detection of metalsolves new applications.

Suitable for operator and machine safety.

Reliable function without specificcoded target.

Connection of the sensors to safety PLCs,bus systems and relays possible.

Meets the requirements ofIEC 61508 SIL3 and ISO 13849-1 PL e.

Certified to IEC 62061, SILcl3.

Application: Manway monitoring

Self-monitoring design without coded magnet orcoded target.2 x PNP switching outputs (normally closed function)Because of the window technology used, i.e. an enablezone monitored for target position and dwell time, acounterpart, e.g. a magnet or a special mechanical tar-get is not required.If the target is removed from the enable zone, the out-put circuits open. The fail-safe sensor can be connectedto approved two-channel evaluation units without cross-monitoring that are suitable for positive-switching non-contact guards. In case of a fault, e.g. cross fault of thewires, the sensor passes into the defined safe state.

Category is history – now there is SIL and PL.In the past you were familiar with categorisation to EN954-1, this has been replaced by SIL and IEC 62061 andPL to ISO 13849-1.The qualitative approach is no longer sufficient so thequantitative approach has been added. The standardsIEC 62061 and ISO 13849-1 now consider also the aver-age probability of failure of components (called prob-abilistic approach).The new approaches have been developed also becausethe EN 954-1 did not take into account the time behav-iour (e.g. test interval, life time).These characteristics of the sensors or the individualcomponents are described in the Safety Integrity Level(SIL 1-3) and the Performance Level (PL a-e).ifm offers you “safe” assistance, today as well as in thefuture. www.ifm-electronic.com/safeYou can find more information on the standards at:www.zvei.org or www.vdma.org
