KLM-Z Guard Locking Safety Switch with RFID and OSSD
The KLM-Z 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. Featuring OSSD outputs, the KLM-Z can be connected in series while maintaining a high level of functional safety.
Four integrated LEDs provide clear device diagnostics for solenoid status, guard position, input, and output status. Designed for small to large guard doors, the KLM-Z helps keep guards securely closed until hazardous motion has stopped or the hazard has been removed.
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.
