Allen-Bradley 871TM-B10N30-A2 Proximity Sensor

Allen-Bradley 871TM-B10N30-A2 is a metal-face, shielded inductive proximity sensor with a 30 mm diameter stainless-steel tubular housing. It operates as a 2-wire AC/DC device and provides a normally open (NO) output, with a nominal sensing distance of 10 mm. Supplied with a 2 m PVC cable, this compact sensor is designed for non-contact detection of metal targets in tight spaces, making it suitable for presence or position sensing on conveyors, end-of-travel applications, and equipment guards. The B10N30-A2 suffix identifies the 10 mm sensing range on a 30 mm body and NO output configuration within the 871TM family from Rockwell Automation. With a stainless-steel body and metal face, the sensor is built for industrial environments where metal-contact sensing is required in constrained installations, while the shielded construction helps minimize electrical interference in noisy factories. For designers and technicians, this 2-wire configuration simplifies wiring in compact control loops, reducing component count in retrofits and new builds alike.
