Interlock Switches Guard Locking Switches 440G-MT Specifications Standards EN954-1, ISO13849-1, IEC/EN602041, NFPA79, EN1088, ISO14119, IEC/ EN60947-5-1, ANSI B11.19, AS4024.1 Category Cat. 1 Device per EN954-1 Dual channel interlocks suitable for Cat. 3 or 4 systems Approvals cULus, TUV Safety Contacts 4 N.C., 3 N.C., 2 N.C. direct opening action Auxiliary Contacts Utilisation Category Description The 440G-MT solenoid switch is a positive mode, tongue operated guard locking interlock switch that locks a machine guard closed until power is isolated and ensures that it remains isolated while the guard is open. The guard may only be opened when a signal is applied to the internal solenoid which releases the lock mechanism. The 440G-MT locking mechanism withstands forces up to 1600N (360lbs) and the die-cast alloy housing is ideal for use in harsh environments. 1 N.O., 2 N.O.
