440K-C21074 Applications
The 440K Cadet 3 tongue interlock detects the open or closed position of a movable machine guard and signals the safety system to stop hazardous motion when the guard is opened. The semi-flex actuator with GD2 metal alignment guide accommodates moderate door misalignment while guiding reliable engagement. Break-before-make contacts with dual N.C. safety channels integrate into safety relays and controllers. The M16 conduit entry with 1/2-inch adaptor eases wiring in a range of installations. The tongue actuator is inserted into the switch head to hold contacts closed.
