Allen-Bradley 871C-P5S18 Inductive Proximity Sensor

Allen-Bradley 871C-P5S18 Inductive Proximity Sensor is a compact M18 (18 mm diameter) cylindrical sensor designed for non-contact metal detection in industrial automation. It offers a nominal sensing distance of 5 mm and operates on a 10-30 VDC supply, making it compatible with standard DC control circuits. Termination is via a 2 m, 2-conductor cable, simplifying installation in control panels; the 18 mm variant of the 871C family typically features a plastic face and threaded barrel. This sensor is rated IP67, providing protection against dust and water exposure in harsh manufacturing environments, and it supports a wide operating temperature range of -25 to +55 °C. The 871C family is used for metal-detection tasks and general automated sensing where a robust, compact, and easy-to-wire inductive sensor is required.
