KLM-Z-SKR-RR QC-M12 Guard Locking Safety Switch with RFID, OSSD, Personnel Key, Rear Release and M12 Quick Connect
The KLM-Z-SKR-RR QC-M12 guard locking RFID safety interlock with OSSD outputs features a slimline metal body profile, designed for 50 mm frames to enable easy retrofitting to new or existing guards. Its robust construction provides a holding force of up to 3000 N, helping to keep medium to large guard doors securely closed until hazardous motion has stopped or the hazard has been removed.
The coded release key, also known as the Personnel Key, can be taken inside the hazardous area, allowing the user to operate safely and without fear of inadvertent start-up. The KLM-Z-SKR-RR also includes a non-latching rear release mechanism, enabling the guard lock to be released quickly from inside the guarded area in an emergency.
