440G-MZ Guard Locking Switch

Our 440G-MZ Guard Locking Switches help protect personnel and are suitable for many types of guard doors, including full-sized guard doors. These switches allow full body access to the safeguarded area, where a high holding force and a wide tolerance to guard misalignment, and an escape release option are commonly required. Our 440G-MZ has embedded GuardLink technology that makes it a smart device and enables premier integration.
