KLTM-RFID QC-M23 Guard Locking Safety Switch with RFID and M23 Quick Connect

The KLTM-RFID QC-M23 guard locking safety interlock with integrated RFID is housed in a heavy-duty die-cast enclosure and provides a holding force of up to 3000 N across two actuator entry points. Designed for medium to large guard doors, it helps keep guards securely closed until hazardous motion has stopped or the hazard has been removed. The integrated M23 connector reduces installation time, minimizes wiring errors, and makes maintenance or replacement faster and more reliable.

The uniquely coded RFID actuator provides high-level coding in accordance with ISO 14119, delivering a high level of anti-tamper protection and helping to prevent unauthorised operation.
