It operates on a 24 VDC solenoid and provides 5 contacts configured as 3 NC + 1 NC / 1 NO, giving you both redundant safety channels and a status feedback signal in a single housing. The orange LED indicator at 24 VDC gives a clear visual confirmation of solenoid state — lit when locked, dark when released — useful during commissioning and fault-finding without needing a multimeter on the terminals. Connection is via a terminal block, so you terminate field wiring directly inside the switch body — no pre-wired pigtail to manage. The 1/2-14NPT conduit entry includes an M20-to-1/2-14NPT conversion adapter, covering both NPT and metric conduit standards out of the box. For existing installations, the D4SL-N3GFG-D is a critical spare worth keeping one in the cabinet.","metaTitle":"Omron D4SL-N3GFG-D Guard Locking Switch, 1300 N Holding Forc","metaDescription":"Omron D4SL-N3GFG-D guard locking switch with 1300 N holding force, 24 VDC solenoid, 5 contacts (3NC+1NC/1NO).
