Due to their reliability and efficiency, inductive proximity switches are used whenever a metal object has to be detected within just a few millimeters:

  • Presence detection of a machine component
  • Ultra precise referencing of the zero position of a moving machine component (e.g. in robotics)
  • Detection of different positions (e.g. limit switches)
  • Counting metal objects (e.g. in component feed or conveyor technology)
  • Presence detection of objects in process
  • Rotary speed measurement on metal gear wheel


Inductive sensors detect any metal object, whether moving or stationary. Sensor operation is non-interacting. Due to their high reserve capacities they are impervious to material adhesion such as metal chips on the sensing face. The sensors are ideal for industrial use. They operate on non-contact sensing, are free from wear and capable of high switching frequencies at yet high switching accuracy. In addition, they are reliably protected against vibration, dust and moisture.
