Guard Locking RFID Safety Switch with Control Functionality (KLM-Z-4ST)
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.
The slim profile body mounts directly to 50mm frame sections, making it ideal for machine guarding applications where space is limited. The actuator head allows both front and end entry and can be rotated to provide up to eight actuation directions, offering excellent flexibility during installation.
- Type 4, High Coded RFID Sensing
