Allen-Bradley 871TM-B15C30-R3 Inductive Proximity Sensor

The Allen-Bradley 871TM-B15C30-R3 is a metal-face inductive proximity sensor designed for non-contact detection of metal targets in industrial automation, delivering a compact 30 mm diameter barrel and a 15 mm sensing distance that fits into tight spaces on conveyors, presses, and assembly lines. The unit features a tubular stainless-steel housing with a metal face, is a 2-wire AC/DC device, and operates as an unshielded sensor, enabling straightforward mounting and wiring in harsh environments. Its normally closed (NC) output switches state when metal enters and leaves the 15 mm sensing field, offering simple wiring schemes for loop-powered or transformer-powered systems, and its 30 mm body diameter supports mounting in compact fixtures. This sensor is part of Allen-Bradley’s 871TM family, a line of metal-face inductive sensors designed for rugged performance in demanding automation tasks.
