Pepperl+Fuchs launches device for precise detection of absolute position of actuators

Pepperl+Fuchs has launched a device for the precise detection of the position of actuators. 

The new PMI F90 inductive positioning system can “precisely detect the absolute position of one actuator as well as the distance between two”, says Pepperl+Fuchs.

The company says the system has “comprehensive communication functionality and is equipped for Industry 4.0 applications”, through IO-Link technology. 

Pepperl+Fuchs says its patented multi-coil technology “guarantees maximum measurement accuracy”.

The new PMI F90 inductive positioning system works with a “unique, patented multi-coil system”.


The company says the absolute position of the actuator is precisely detected from the measuring signals of a single coil. In addition to sending the analog position signal, switch points can also be defined.

The sensor can detect two actuators as well as the distance between them, meaning that dynamic positioning tasks can be completed with the smallest amount of measuring technology.

The device enables continuous data flow thanks to its IO-Link interface, in particular for applications featuring Industry 4.0 architecture.

Event logs, error messages, signal quality data, device status, and operating hours can all be read directly by the IO-Link master.

The PMI F112 and PMI F166 sensors from this product family are available for confined areas and harsh environments.

The compact design allows these sensors to be installed in even the tightest of spaces while the robust metal housing protects them from external influences.

The advantages of the inductive measuring principle apply to all devices: noncontact, low-wear and maintenance-free, dirt-resistant, and resistant to interference.

All steel components or objects can generally be used as actuators since the inductive system is not reliant on a magnetic actuator.

The new system’s features include:

  • Position detection independent of distance
  • Programmable measurement range and switching range
  • Measuring and switching functions in a single device
  • Parameterization via IO-Link
  • Versions for ATEX Zone 2/22

Pepperl+Fuchs claims to be one of the world’s leading providers of industrial sensors and explosion protection, and has been in existence for more than 70 years.
