It uses two normally closed contacts (DPST‑NC) and provides a 3 m potted lead cable, making integration straightforward into guard circuits. The device is rated for up to 100 V (AC\/DC) and 250 mA, and it offers an IP67 enclosure rating for robust operation in dirty or damp environments. With a sensing range of approximately 5–15 mm, it coordinates with standard door actuators and guard interfaces to enforce safety conditions before machine restart. The 2187 variant indicates contacts are individually lead-out, and the 3M suffix confirms the 3-meter cable length included with the part. Typical applications include safety interlock duties on movable guards for presses, CNC machines, and robot-integrated work cells, where guarding a hazardous access point is essential. This Schmersal part is commonly paired with compatible safety controllers to monitor lock status and ensure proper lock release sequencing in automated production lines.\u003c\/p\u003e\u003c\/div\u003e","brand":"Schmersal","offers":[{"title":"New","offer_id":46283999740138,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-021.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schmersal-bns33-02z-2187-3m-door-interlock-safety-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
