It detects the presence of metal targets without contact, outputting a PNP normally-open signal. This sensor is used in automation lines to confirm position, detect end-of-stroke, or count parts on a conveyor.
The M12 barrel mounts through a 12 mm hole in a bracket or machine frame, with a lock nut to secure it. The PNP output connects directly to a PLC digital input or safety relay. The sensor body is rated for industrial environments; no IP rating is listed in the spec, so verify sealing against washdown or coolant exposure before specifying in wet areas.
