The E2B-M30KN20-WP-C1 2M: The brass housing with metric thread (short body) mounts into standard M30 knockouts. Unshielded construction means the sensor needs a free zone around the face — plan for twice the rated sensing distance to the side for reliable detection. NPN output is intended for sinking inputs; verify the PLC or controller input type before wiring. Pre-wired PVC cable is robust for dry indoor environments but should be protected from coolant or oil splash.

Frequently asked questions
Can I use the E2B-M30KN20-WP-B1 2M (PNP) as a substitute?
Mechanically identical — same 30mm brass body, 2m cable, 20mm sensing distance — but the output switches from NPN (sinking) to PNP (sourcing). If your control input is designed for a sinking signal, the PNP version will not drive it without reconfiguration or a level converter. A deviation from the AML would be required.
What is the mounting pitch and clearance requirement?
The sensor body is 30mm diameter with metric thread, short barrel. As an unshielded type, it requires a free zone around the sensing face of at least 40mm (twice the rated sensing distance) to avoid false triggers from proximity to metal.
