KLM-RR Guard Locking Safety Switch with Rear Release

The KLM-RR (SAMLOCK) guard locking safety interlock features a slimline metal body and a holding force of up to 3000N to keep small to large guard doors closed until hazards have been removed. A non-latching manual escape release is provided to enable quick release of the switch lock in case of emergency.

Manufactured from die-cast metal
Holding Force up to F1Max 3000N (300Kg)
Functions as a power-to-unlock device
Rotating head for up to 8 entry positions
Ingress Protection up to IP67
Connectivity via 3 x M20 or ½” NPT

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.
