KLM-Z-4ST
Guard Locking RFID Safety Switch with Control Functionality
The KLM-Z-4ST is a Type 4 guard locking safety switch with integrated RFID, OSSD outputs, and additional machine control functionality built directly into the switch lid.
Designed for applications where both guard locking and local machine control are required, the KLM-Z-4ST can incorporate up to four standard 22mm pushbuttons. This helps reduce the number of separate devices required at the gate, simplifies wiring, and provides a more convenient, compact solution for operators.
