KLM-RR-SS Guard Locking Safety Switch with Rear Release and SS Head

The KLM-RR is a guard-locking safety interlock designed to keep small to large guard doors securely closed until hazardous machine movement has stopped. Featuring a rugged stainless steel head, robust metal body and a holding force of up to 3000N, it provides reliable protection in demanding industrial environments. A non-latching manual escape release is included, allowing the switch lock to be quickly released from inside the guarded area in the event of an emergency.

Die-cast metal construction
316 stainless steel head
Holding force up to F1Max 3000N (300kg)
Functions as a power-to-unlock device
Rotatable head provides up to 8 entry positions
Ingress protection up to IP67
Connectivity via 3 x M20 or ½” NPT conduit entries

KLM-RR Rear Escape Release
Where the Risk Assessment for the application permits, a non latching manual escape release version (KLM-RR) enables quick release of the switch lock in case of emergency. The switch can be mounted such that access to the release button is available from inside the active guard area. Pressing and holding the release button will release the lock mechanism and open the lock monitoring contacts, whilst the guard can be pushed open. Measures should be taken to reduce the risk of improper activation.
