The Omron D4GS-N1R-5 is a slim-profile safety door switch designed for interlocking guard doors on machinery. Its 1NC/1NO slow-action contact block provides a positively driven NC channel for the safety circuit and an NO channel for status feedback — the NC opens when the door opens, even if contacts weld, meeting the direct-opening requirement of IEC 60947-5-1. The 60 N min direct opening force ensures the NC contact mechanically breaks under actuator removal, a key criterion for safety-rated guard interlock applications up to PL d / SIL 2. Cable length is 5 m, sufficient to reach a panel entry without a junction box on most machine frames. The R suffix in the order code means horizontal key insertion, so the actuator enters from the side — confirm your door's swing direction matches this orientation before specifying.
For BOM freeze or PPAP submissions, the mature status means the design is stable and no imminent PCN is expected.
Minimum applicable load is a resistive 4 mA at 24 VDC — this is the N-level reference value, meaning the switch reliably wipes oxidation at low currents. If your safety PLC input card sinks less than 4 mA at 24 V, you may need a pull-up resistor to ensure contact wetting. Rated operating frequency is 30 operations/minute max, which governs the mechanical endurance over the switch's life. For high-cycle doors (e.g., pick-and-place cell guards cycling every 2 seconds), this switch would exceed its rated frequency — choose a higher-rated model. The slim body (about 30 mm wide) fits in tight panel cutouts or on aluminum profiles where standard safety switches won't clear adjacent components.
