The Omron E2EX8B3D18M1OMS is an M18 inductive proximity sensor in the E2E-Next series, flush-mounted in a brass nickel-plated housing, terminated with an M12 4-pin connector and rated to 8 mm sensing distance — that headline number governs where the target has to land in front of the face. Output is PNP with a programmable NO/NC function, so the same order code covers either switching logic depending on how the IO-Link parameter (or wiring) is set on the E2E-Next platform. It runs from a 10–30 V supply, draws 20 mA, switches up to 100 mA of load, and cycles at 500 Hz. Sealing to IP67 and IP69K on an operating range of −40 °C to 85 °C means it survives washdown, food-and-bay CIP, and unheated outdoor cabinets without derating — the sensor, not the connector, is what sets the environmental ceiling.
Where it drops in
Mechanical fit is a 53 mm M18 barrel with flush mounting, so it goes into the same through-hole and nut as any other M18 flush inductive sensor — no bracket rework, no spacer plate, just confirm the 8 mm rated sensing distance against the actual target travel in the application. The M12 4-pin connector means the field side uses a standard M12 patch cord; cable selection is the integrators call, not the sensors — pick a 4-pin, shielded run if the run sits next to a VFD output cable.
Cross-shopping the cable-out sibling
The closest functional second-source candidate inside the same E2E-Next family is the E2EX8B3D185MOMS, which carries identical 8 mm sensing distance, identical 10–30 V / 100 mA / 20 mA / 500 Hz envelope, identical PNP NO/NC output and identical IP67/IP69K sealing.
