Leading Manufacturer of Safety Interlock Switches and Machine Guard Safety Switch Devices for Automation and Process Safety

Guard Locking RFID Safety Switch with OSSD, Rear Release and Trapped Key (KLM-Z-SKR-RR)

The KLM-Z-SKR-RR guard locking RFID safety interlock with OSSD outputs, features a slimline metal body profile for 50mm frames to enable easy retrofitting to new or existing guards. The robust design allows for a holding force of up to 3000N to keep medium to large guard doors closed until the hazard/s have been removed. The coded release key (Personnel Key) can be taken inside the hazardous area to allow the user to operate safely and without fear of an inadvertent start-up occurring.
