Allen-Bradley 871C-K5A18 is an inductive proximity sensor (proximity switch) from Rockwell Automation’s Allen‑Bradley line, designed for non‑contact metal target sensing in automation environments. It operates on a DC supply of 10–30 V and draws up to 0.2 A, making it compatible with common industrial controllers and standard wiring practices. As a member of the 871C family, this variant is intended for compact mounting in machinery and conveyors where reliable metallic sensing is required without physical contact.
