The Omron E2B-M12KS04-M1-C1 is a shielded inductive proximity sensor on an M12 threaded cylindrical body, delivering a 4 mm sensing distance via a three-wire NPN-NO output. The connector termination keeps field wiring fast, and the IP67 rating allows washdown exposure — a standard profile for part-present sensing on pick-and-place, conveyor, or packaging machinery.
Panel-fit memo vs. peer E2B-M12LS04-WP-B2 2M
If your BOM was built around the E2B-M12LS04-WP-B2 2M, note that sensor is a PNP-NC variant with a 2-meter cable termination. The output logic and termination both differ, so swapping into an existing cabinet without rewiring or changing the connector interface isn't possible. Keep the NPN-NO order if the PLC input card expects sinking logic.
Mounting and wiring constraints
Threaded M12 body with a 1 kHz response frequency. Shielded construction allows flush mounting in metal — no derating on the 4 mm nominal sensing distance when embedded. Supply voltage 10-30 V, operating temperature -25°C to 70°C. The connector mates with a standard M12 3-pin female cordset (not included). Verify the free-wheeling diode polarity if driving an inductive load downstream.
