1 / 4 page 3-36 Interlock Switches Guard Locking Switches 440G-MT 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. The 440G-MT solenoid switch is designed for machines that do not stop immediately or where premature interruption of the machine could cause damage to tooling and components or cause an additional hazard. Features • Mechanical lock • High locking force—1600N (360lbs.) • Heavy duty die-cast alloy housing ideal for harsh environments Specifications Standards EN954-1, ISO13849-1, IEC/EN60204- 1, 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 1 N.O., 2 N.O.
