Its 1NO+1NC contact configuration sets how many circuits the e-stop can interrupt directly versus how many need to run through a safety relay. The 40 mm mushroom profile keeps the button reachable and visible at a distance, and the IP66\/IP67\/IP69\/IP69K sealing means wash-down or outdoor mounting does not compromise the latching mechanism.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eFitted to machine control panels, conveyor lines and operator stations as the primary manual stop function, wherever a 22 mm panel cutout and a 1NO+1NC contact block match the safety circuit design.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54074912997659,"sku":"XB4BS8445","price":20.45,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-xb4bs8445-xb4-emergency-stop.jpg?v=1790852104","url":"https:\/\/stoklink.com\/products\/schneider-electric-xb4bs8445-harmony-xb4-emergency-stop","provider":"Stoklink","version":"1.0","type":"link"}
