Allen-Bradley 871C-A5C18-R3 Proximity Sensor

Allen-Bradley 871C-A5C18-R3 is a compact inductive proximity sensor in an 18 mm nickel-plated brass tubular housing, designed to detect metal targets with a 5 mm sensing distance in tight industrial spaces. It operates from 20 to 250 V AC and provides a normally closed output via a Micro Quick Disconnect AC connection for straightforward, panel-friendly wiring. This AC full-featured model from the 871C family is built for inline position sensing on conveyors, machine tools, and other automation equipment where a small footprint matters, offering rugged performance in cramped installations. With its tubular form factor and nickel-plated brass body, it accommodates tight mounting tolerances while delivering reliable metal sensing in routine industrial environments.
