Allen-Bradley 871C-D2NP12-D4 Inductive Proximity Switch

Allen-Bradley 871C-D2NP12-D4 Inductive Proximity Switch is a cylindrical, DC-powered sensor from the 871C-D family designed for non-contact metal detection in industrial automation. The 12 mm cylindrical housing provides a compact form factor suitable for tight mounting on machinery, conveyors, and automated cells, while delivering reliable switching for position sensing and part presence checks in manufacturing environments. As a cylindrical inductive proximity switch, it detects nearby metal targets without moving parts, helping to streamline control signals for downstream equipment and contribute to safer, more efficient automation cycles. This variant aligns with Allen-Bradley’s robust 871C-D design language, featuring a durable enclosure and predictable performance characteristic of DC-powered inductive sensors in this family, making it a common choice for sensing metal components on actuators, end-of-arm tooling, and conveyor lines.
