The E2E-C03N02-WC-B1 2M: This 3 mm cylindrical unshielded inductive proximity switch from the E2E Small Diameter series is sized for detecting tiny metal targets in cramped machinery—think cam lobes, miniature actuator positions, or edge detection on small assemblies. The PNP normally-open output with a 2 m PVC cable covers standard PLC sourcing inputs; the 2 mm sensing distance is measured to a standard iron target, so derate for other metals. Unshielded means you cannot flush-mount it in metal; the surrounding material must be non-ferrous or recessed.
Check the mounting: smooth bore, no threads
The cylindrical/smooth case (no thread) requires a clamp or split-ring bracket sized for 3 mm. The 2 m PVC cable is pre-wired and fixed—no connector option, so plan a service loop inside the enclosure. The first thing to verify when the box arrives: the sensor head must not be within one diameter (3 mm) of any metal other than the target if you want full 2 mm range.
