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
