Allen-Bradley 871C-P8B18 Inductive Proximity Switch

Allen-Bradley 871C-P8B18 is a cylindrical inductive proximity switch in Rockwell Automation's 871C family, designed for non-contact detection of metal targets in industrial automation and control systems. As part of the 871C Series, these miniature tubular sensors provide switching without moving parts in challenging environments, enabling reliable metal-detection for applications such as position feedback and end-of-travel sensing. The 871C family is documented as miniature tubular inductive proximity sensors, with DC-powered variants; consult Rockwell's official product literature for the exact electrical characteristics, sensing distance, output configuration, and compatibility for this specific P8B18 model.
