Japan




The Omron STI D4SL-N4VFG-N is a heavy-duty (1300N holding force) safety door lock switch designed for industrial 
applications. It uses a standard metal key to lock the guard door, and features separate Normally Closed (NC) 
contacts for monitoring both the door position and the lock status. This allows safety control systems to detect 
unauthorized access or lock malfunctions. Made from a robust plastic housing with a resin head, the switch boasts an 
IP67/UL Type 4X rating for dustproof, waterproof operation even outdoors, and operates within a temperature range of 

-10°C to +55°C.
