440G-MT Applications

A robust guard locking interlock that holds an access guard mechanically locked while a machine runs, releasing only when the control system energizes the internal solenoid. Power-to-release operation keeps the guard secured through a stop or power loss until the hazard has come to rest, protecting operators from residual motion on presses, robots, and rotating machinery. The 1500 N holding force and die-cast housing withstand demanding duty, and the design supports high safety performance levels for compliance with modern machine safety standards.
