Operating on a 24 VDC (±20%) power input, it provides PNP outputs with a maximum load current of 50 mA and supports wiring resistance up to 2.5 ohms. Equipped with an M12 quick-disconnect connector, this switch delivers reliable door position monitoring and guard locking for high-safety industrial environments.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eTechnical

Keyence's GS Series of safety interlock switches designed to prevent hazardous machine operation when safety doors or hatches are open. Its power-to-release locking model ensures the guard remains locked during power failure or emergency stop conditions, releasing only when an active control signal is applied. Compatibility extends to standard 24 VDC safety relay modules, safety PLCs, and Keyence GS Series safety controllers. It is commonly implemented in robotic enclosures, automated packing cells, stamping presses, and high-risk machine guarding installations.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003col start=\"3\" data-path-to-node=\"4\"\u003e\u003c\/ol\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"5,0,0\"\u003eSwitch Mechanism: Power-to-release guard locking safety switch\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,1,0\"\u003eOperating Power: 24 VDC (±20%) supply input\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,2,0\"\u003eOutput Configuration: PNP semiconductor safety outputs\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,3,0\"\u003eLoad Current Capacity: 50 mA maximum output load current\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,4,0\"\u003eWiring Load Resistance: Up to 2.5 ohms maximum allowable wiring resistance\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,5,0\"\u003eConnection Type: Integrated M12 quick-disconnect connector\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,6,0\"\u003eDevice Classification: Standard-type safety interlock switch\u003c\/li\u003e\n\u003cli data-path-to-node=\"5,7,0\"\u003eUnit Assembly Weight: Durable 0.45 kg enclosure construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe GS-51PC delivers the reliability and precision required for automated guard locking and machine safety interlock protection.\u003c\/p\u003e\n\u003cp id=\"p-rc_c7b8f4fae39e183e-25\"\u003e\u003c\/p\u003e\n\u003cul\u003e\u003c\/ul\u003e\n\u003cul\u003e\u003c\/ul\u003e","brand":"Keyence","offers":[{"title":"Default Title","offer_id":52927878431018,"sku":"GS-51PC","price":425.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/0392\/4266\/files\/s-l1600_f81527e3-a193-4ccc-af50-7f0374295dae.webp?v=1791899732","url":"https:\/\/iqelectro.com\/products\/keyence-gs-51pc-power-to-release-safety-interlock-switch-m12-pnp","provider":"IQElectro","version":"1.0","type":"link"}
