Its 2NC/1NO slow-action contact block gives you two normally-closed safety channels for the monitoring circuit and one normally-open signal contact for the PLC or indicator — a common configuration for Category 3 or PL d safety circuits per EN 60947-5-1. The 3 m cable is factory-moulded, so no field wiring on the switch body; you land the other end in the control cabinet or junction box. Horizontal key insertion (R) means the actuator enters from the side, which suits sliding or hinged guards where vertical access is awkward. The conventional free-air thermal current (Ith) is 2.5 A per EN 60947-5-1 — that's the continuous current the contacts can carry in open air without exceeding temperature rise limits. For a safety switch feeding a 24 VDC safety relay or PLC input, 2.5 A is generous; the real limiter is the conditional short-circuit current of 100 A, meaning the switch is protected by a 100 A fuse or breaker upstream (typically a 6 A gG or 10 A gG in practice). Operating speed is 0.1 to 0.5 m/s — slow enough that the slow-action contacts don't bounce, fast enough that the guard doesn't linger in the half-open zone. At 30 operations per minute max, it's not meant for high-cycle counting; it's a guard interlock, not a limit switch for a fast indexer.","metaTitle":"Omron D4GS-N3R-3 Slim Safety Door Switch, 2NC/1NO, 3m Cable","metaDescription":"Omron D4GS-N3R-3 slim safety door switch with 2NC/1NO slow-action contacts, 3m cable, rated Ith 2.5 A.
