Allen-Bradley 871TM-B4N12-B4 is a metal-face inductive proximity sensor with a 12 mm tubular housing and a 4 mm nominal sensing distance, designed for reliable non-contact detection of metal targets in industrial equipment. It operates as a 2-wire AC/DC device with an unshielded configuration and a normally open output, featuring a stainless-steel body and a durable metal face for harsh environments. Typical applications include end-of-travel sensing and position monitoring on conveyors, presses, and automation lines where robust metal-target detection is required without physical contact.
