ifm continues to innovate safety safely
ifm electronic now has a whole family of inductive sensors and switches that are safe to use in a Category 4 (EN954-1) or SIL 3 (EN61508) situation
ifm electronic now has a whole family of inductive sensors that are safe to use in a Category 4 (EN954-1) or SIL 3 (EN61508) situation As many customers have already found, no longer is there any need to rely on mechanical devices alone in a safety application

A pump cavitation sensor at last!
The ifm electronic pump diagnostic pressure sensor detects cavitation, trapped air and blockages, just what you have been waiting for!
The range now covers rectangular (40x40) types both flush and non-flush, M30 and M18 devices.
The M30 is even available in a version for safe use in hazardous areas (safety Cat 3 and ATEX 3D/3G).
The Cat 4 M30 is designed with food washdown environments in mind, being constructed of stainless steel and PEEK, with an IP69K rating.

The stainless steel M18 is also rated to IP69K.
All fail-safe inductive switches from ifm electronic are constructed with full redundant and diverse internal circuits, certified by TUV Rhineland, but otherwise has all the advantages of an inductive sensor: with no moving parts, IP67, standard M12 connector etc.
Now you may think an inductive sensor which needs no special target would be easy to defeat? But that would defeat the object of safety! The target may be nothing special, but its position in the right place at the right time is what counts.
When the target is present, any other piece of metal between the switch and the target will cause the output to switch off.
Setting the unit is not difficult either, because the LED helps in adjustment, while incorporating a delay to befuddle the fiddlers.
To operate, the fail-safe switch from ifm electronic is connected to an external controller with safe outputs, though it could equally be connected to a safety plc running approved software, and ifm electronic also offer a safety slave for AS-interface Safety at Work with the controller built in, capable of monitoring eight fail-safe inductive switches simultaneously.
Functional safety is assured with the ifm electronic fail-safe inductive system; coil damage, component health, cross-monitoring, short-circuit protection: all aspects are continuously checked by a test pulse from the controller or plc.
Any fault, at any time is instantly signaled.
ifm electronic specialises in the application of advanced electronic technology to produce innovative and effective solutions for industrial control applications.
Products include flow sensors; pressure transmitters and switches; temperature switches and transmitters; capacitive, inductive and photoelectric proximity sensors; and a full range of AS-i I/O modules and masters.
ifm is committed to working closely with its customers to develop products which precisely match their needs, and the company provides expert, readily accessible technical support to help users maximise the benefits they gain from ifm products. Request a free brochure from IFM Electronic ...
