Allen-Bradley 871C-M2NP5-E2 Inductive Proximity Sensor

Allen-Bradley 871C-M2NP5-E2 is a compact, stainless-steel tubular inductive proximity sensor with a threaded barrel designed for tight spaces. The 3-wire DC device operates on 10–30 V DC and typically draws about 200 mA, making it compatible with standard PLC inputs and control circuits, and it features a 1.5 mm sensing distance. It provides a normally open (N.O.) output configured as a PNP (source) switch, sourcing current to the load when metal is detected, and it ships with a PVC insulated 3-conductor cable. IO‑Link enabled, the sensor can be configured and diagnosed via IO-Link masters in addition to traditional wiring, supporting richer diagnostics and integration into smart factory networks. The M5-threaded barrel and miniature form factor suit applications such as fixture sensing, end-of-arm tooling, and other compact automation tasks where metal targets must be detected without contact. This variant is part of the 871C family of miniature inductive sensors and is supported by Rockwell Automation, ensuring compatibility with Rockwell software and typical DC control architectures. With its corrosion-resistant housing and precise 1.5 mm sensing range, the 871C-M2NP5-E2 offers reliable metal detection in demanding manufacturing environments while maintaining a small footprint for tight installation spaces.
