{"product_id":"allen-bradley-871tm-bh2n12-r3-inductive-proximity-sensor","title":"Allen-Bradley 871TM-BH2N12-R3 Inductive Proximity Sensor","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 871TM-BH2N12-R3 is a 12 mm diameter, shielded inductive proximity sensor with a metal-face, stainless-steel tubular housing designed for non-contact detection of ferrous metal targets. It delivers a 2 mm nominal sensing distance and an normally open (N.O.) output in a 2-wire AC\/DC configuration (PLC Interfacer), with a broad operating supply range of 20 to 250 VAC or DC. The rugged construction and metal face provide durability in demanding industrial environments, while the compact form factor supports mounting in tight spaces on conveyors, machining cells, or automation lines. When a metal target enters the 2 mm sensing zone, the N.O. output switches, supplying a clean digital signal suitable for PLC inputs and automation controllers. As part of the Rockwell Allen-Bradley 871TM family, this model is intended for seamless integration with Allen-Bradley controls and compatible systems that support AC\/DC proximity sensors, with straightforward wiring into standard input modules. Common applications include presence or intrusion detection of metal parts along conveyors, end-stop or home-position sensing in automated fixtures, and other short-range metal-detection tasks within manufacturing, packaging, and material-handling environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51657240379694,"sku":null,"price":196.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_854d0b36-ffa2-46b3-827d-1a398a2478e7.jpg?v=1769467053","url":"https:\/\/plgautomation.com\/products\/allen-bradley-871tm-bh2n12-r3-inductive-proximity-sensor","provider":"PLG Automation ","version":"1.0","type":"link"}
