Allen-Bradley 871C-P8B18 Inductive Proximity Switch Sensor

The Allen-Bradley 871C-P8B18 Inductive Proximity Switch Sensor is a cylindrical inductive proximity sensor designed for non-contact metal detection and precision position sensing in harsh industrial environments. It has an 8 mm sensing distance, a 3-wire DC normally open output, and operates on 10–30 V DC with an output current up to 200 mA. The IP67-rated housing uses a cylindrical threaded barrel and a cable connection for robust integration in conveyors, packaging machines, and automated assembly equipment. Designed for replacement or retrofit in automated production lines, this 871C Series sensor from Allen-Bradley (Rockwell Automation) delivers reliable non-contact detection in dusty, oily, and vibration-prone settings.
