The Allen‑Bradley 871D-BW2N260-R3 Cylinder Position Proximity Sensor is a two‑wire AC/DC inductive proximity switch designed to detect hydraulic cylinder piston position in in‑port cylinder configurations. It offers a 2 mm nominal sensing distance and a 26.0 mm probe length, with a blue color code and a normally open (N.O.) output. The device uses a Micro QD (AC) connector and supports standard AC/DC power for straightforward integration into automation circuits. As part of the 871D hydraulic cylinder position family, this model is intended for reliable cylinder‑position sensing in automated machinery and manufacturing lines.
