Allen-Bradley 871-C-D1NN5-P3-A Proximity Switch

Allen-Bradley 871C-D1NN5-P3 is a compact inductive proximity sensor in a small-barrel, stainless-steel tubular housing with threaded mounting for robust installation in tight spaces. This 3‑wire DC device provides a normally open (NO) output with a sinking (NPN) configuration, making it compatible with common PLC inputs andLogic. The 871C family is designed for metal detection at close range, and the 0.8 mm nominal sensing distance suits small metal targets on assemblies, guides, or end-of-line fittings where space is at a premium. The P3 variant includes a Pico QD quick-disconnect interface for rapid wiring and convenient field replacement, reducing downtime on automated equipment. Durable construction and precise sensing behavior align this sensor with industrial tasks such as position sensing, part presence verification, and end-stop detection in automation lines, where a compact, corrosion‑resistant sensor is required.
