Allen-Bradley 871FM-A2N12-A2 Inductive Proximity Switch

Allen-Bradley 871FM-A2N12-A2 Inductive Proximity Switch is a compact, flat-pack sensor in Rockwell Automation’s 871FM line designed for non-contact detection of metallic targets in tight spaces. The miniature device uses a chrome-plated metal housing and measures roughly 40 x 26 x 12 mm, enabling easy mounting in crowded control panels, on conveyors, or near machine beds where space is limited. As part of the 871FM miniature flat-pack family, it delivers robust reliability for industrial applications requiring simple, maintenance-free sensing without physical contact. The A2N12-A2 variant shares the line’s core characteristics: a small rectangular sensor that can be mounted flush or on a surface to monitor metal presence as part of automated sequences, end-of-travel sensing, or position checks in manufacturing and packaging equipment. Designed for use in environments where metal-detection is needed in a compact form factor, this sensor integrates with standard control architectures and is compatible with Allen-Bradley systems commonly used across manufacturing facilities worldwide. Its compact footprint and metal face help resist wear in challenging production lines, while the flat-pack design minimizes intrusion into crowded assemblies and supports versatile installation angles and mounting options in industrial automation setups.
