Guard Locking RFID Safety Switch with Control Functionality, Trapped Key (KLM-Z-SKR-5ST)
The KLM-Z-SKR-5ST is a Type 4 guard locking RFID safety switch with OSSD outputs, integrated machine control functionality and a coded personnel key.
Designed for applications where guard locking, local machine control, and controlled access are required in one compact device, the KLM-Z-SKR-5ST can incorporate up to five 22mm control elements. This helps reduce the number of separate devices required at the gate, simplifies wiring, and provides operators with convenient control directly at the access point.
The coded personnel key is designed to be removed and taken into the guarded area by the operator or maintenance personnel. While the key is removed, the safety circuit cannot be reset, helping to prevent inadvertent machine start-up while work is being carried out inside the safeguarded area.
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.
