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

Guard Locking Safety Switch Power to Lock up to 3000N (KLTM-P2L)

The KLTM-P2L guard locking safety interlock features a low profile body and with industry standard 73mm fixing centre, 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. 24Vdc must be supplied to the solenoid to keep the guard locked.
