IDEM non-contact RFID coded safety switches are designed to provide interlock protection on hinged, sliding or removable guard doors and are particularly advantageous when poor guard alignment exists, when high-level anti-tamper is required or where high-hygiene washdown requirements exist. New IDEM KLP-Z/KLM-Z/KL3-Z tongue interlock safety switches, with guard locking and RFID coding, fit into the leading edge of machine guard doors to provide robust guard locking while also providing a double tamper-resistant interlock mechanism. Providing position detection for moving guards, these switches remain locked until the solenoid voltage is applied to the switch. The switches can also be used with delay timers to provide the energize signal after a set time has passed. IDEM cULus and CE approved guard locking RFID coded safety switches start at $291.00, with a 1-year warranty.
