Overview
The Allen-Bradley 440G-MT47163 is a Type 2 interlocking guard locking switch from Rockwell Automation’s Guardmaster® safety product line. This positive-mode, tongue-operated guard locking interlock switch locks a machine guard closed until power is isolated, and the guard may only be opened when a signal is applied to the internal solenoid, which releases the lock mechanism. The 440G-MT47163 is engineered for industrial automation systems requiring robust machine safety compliance.
Key Features
- 24V DC solenoid voltage with diagnostic function and metal override key
