Proximity Sensors

Proximity sensors emit a high-frequency magnetic field and detect an upset in the field when an object enters it. They can be used to detect the presence or absence of an object.


Example of a proximity sensor

  • Sensing of tank or bin level
  • Confirmation of part or object passage
  • Detection presence or absence of object
  • Positioning of work piece


  • Non-contact
  • Work in harsh environments
  • Small sensors are available for installation in tight areas
  • Fast response speed
