The unit is specified as part of the Guardmaster\/SensaGuard line and is described as a non-contact interlock switch, suitable for integration with standard safety-relay architectures, with 3 PNP outputs for wiring in safety circuits. Its 10-meter cable length provides flexible mounting options for compact enclosures and longer reach between the door and the control system. As a 440N-Z21SS2BN9 model, it belongs to Allen-Bradley’s Sensaguard RFID non-contact interlocks, commonly used to secure access doors on safety guards and to help ensure the guard remains closed during machine operation. \u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46250766369002,"sku":null,"price":223.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-080.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-440n-z21ss2bn9-non-contact-safety-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
