  • 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
