KLM-RR-SS QC-M23 Guard Locking Safety Switch with Rear Release, M23 Quick Connect and SS Head

The KLM-RR QC-M23 safety interlock switch, fitted with a stainless-steel head, features a slimline metal body and provides a holding force of up to 3000 N to help keep small to large guard doors securely closed until hazardous motion has stopped. A non-latching manual escape release allows the switch lock to be released quickly in an emergency. The integrated M23 connector reduces installation time, helps prevent wiring errors, and makes maintenance or replacement faster, simpler, and more reliable.

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.
