Non-Contact Door and Gate Sensing Switches Selection

Non-contact safety switches work in easy-to-deploy pairs where a coded switch mounted on a frame detects the presence or absence of an actuator mounted on a door or other mechanical guard.
 
  • Two piece design where sensor and actuator do not contact
  • Accommodating to misalignment
  • IP69 solutions available
  • Available with the highest level of tamper resistance
  • Available in cable or QD (quick disconnect) models
