Allen-Bradley 871C-DH2M12-A2 Inductive Proximity Sensor

The Allen-Bradley 871C-DH2M12-A2 inductive proximity sensor delivers reliable non-contact metal detection in industrial automation with an IP67, M12-threaded housing. It detects metal targets at approximately 2–5 mm, operates on 10–30 VDC, provides an NPN normally open (NO) output up to 200 mA, with a ~500 Hz response, and uses a 4-pin M12 connector; the housing includes a built-in LED status indicator and supports an operating temperature range of -25 °C to +70 °C. Commonly deployed in conveyors, packaging machinery, robotic cells, assembly lines, material handling, pick-and-place systems, CNC equipment, and safety interlock configurations to support reliable sensing and process control.
