Allen-Bradley 871P-DD29NB140-A2 is a DC inductive proximity sensor in a rectangular can housing, part of the 871P Proximity Can Motion Sensor family. It provides a nominal sensing range of 29 mm for metal targets and a normally open output that can be wired as sinking (NPN) or sourcing (PNP). The unit is furnished with a PVC jacketed cable about 2 meters long for field wiring, making it suitable for compact, on-machine mounting in harsh industrial environments. Typical applications include position or motion sensing on automation lines, conveyors, and tooling where reliable metal-detection-based switching is required.
