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

Allen-Bradley 871FM-M2NP5-E2 is a miniature rectangular inductive proximity sensor designed for metal detection in tight spaces within control panels and automation assemblies. It uses a 3‑wire DC supply and provides a normally open PNP (sourcing) output, paired with IO-Link 1.0 communication for straightforward integration with modern automation systems. The housing is chrome‑plated brass with a flush‑mount plastic face, in an M5 square footprint, and it supports side sensing with a 1.5 mm sensing distance. It operates on a 10–30 V DC supply and draws up to 200 mA, with a three‑conductor PVC cable for reliable wiring. This shielded sensor sits in the 871FM family, delivering a compact form factor combined with IO-Link compatibility to streamline installation, monitoring, and maintenance in industrial environments.
