AutomationDirect C18P-AN-1E is an 18 mm tubular photoelectric sensor designed for polarized retroreflective sensing, delivering a 2 m sensing range with a dark-on output and visible red light emission. It operates on 10–30 VDC and provides an NPN, 3-wire output through a 4-pin M12 connector. As a polarized retroreflective type, it requires a reflector (sold separately) to establish the sensing target. Its compact tubular form is well suited for installation on conveyors, packaging lines, and automated machinery where reliable switching of small loads is needed, with a standard M12 connection for straightforward wiring.
