The Omron D4GS-N2T-5 is a slim-profile safety door switch with two normally-closed (2NC) slow-action contacts, a 5 m cable, and vertical key insertion. It is designed for interlocking guard doors on industrial machinery where space is tight — the slim body fits where a standard safety switch would not. Rated conventional free-air thermal current (Ith) of 2.5 A per EN 60947-5-1, with a conditional short-circuit current of 100 A. Operating speed range of 0.1 to 0.5 m/s and a maximum operating frequency of 30 operations per minute define the mechanical limits for the door motion it can safely monitor.
The 2NC contact configuration is the safety-relevant pair — two normally-closed channels in series, which is the standard wiring for a dual-channel safety circuit feeding a safety relay or safety PLC. The slow-action contacts (not snap-action) mean the switch state changes at the speed the door moves, which is typical for guard interlocking where the actuator must be positively driven out of the switch body. Vertical key insertion (T suffix) means the actuator enters the switch from above. This determines the mounting orientation of the switch relative to the guard door hinge — critical to get right when replacing an existing switch in a panel or machine frame. The 5 m cable is factory-attached and permanently sealed into the switch body. No field-wiring or connector changes possible — the cable length is fixed, so plan the routing and junction box location accordingly.
