What the part is and where it lands
The Omron E2EX8B1T182MOMS is an M18 flush-mount inductive proximity sensor from the E2E-Next series, switching a PNP normally-open output on detection of a ferrous target up to 8 mm away. It runs on a 10–30 V DC supply, draws 16 mA and sources up to 200 mA to the load, which is what the input card or counter module on the receiving end has to budget for. This class of sensor is used for non-contact position detection on conveyors, indexing tables, valve actuators and bottle/can lines where a discrete PNP input feeds a PLC or counter.
Ratings that actually drive the fit
The 8 mm nominal sensing distance on a flush M18 body is the headline number for panel layout — set the target approach inside that range and account for the standard derating on non-ferrous metals. 500 Hz switching frequency is the ceiling for high-speed indexing or small-part counting; above that pulse rate the output will start to miss and the PLC will see a stretched or dropped pulse train. IP67, IP67G and IP69K together cover the full washdown spectrum from temporary immersion to high-pressure hot caustic and steam — the IP69K rating is what allows daily hot washdown on a food or beverage line without sealing the threads. -40 to 85 °C operating envelope means the sensor rides along in unheated cabinets, engine rooms or near ovens without a separate cold-weather spec on the BOM. The nickel-plated brass housing is a smooth, drainable shell — no exposed fasteners in the sensing face, so there is nothing for product residue or cleaning chemistry to hang on to between CIP cycles.
Mounting and wiring in the panel
The 55.3 mm body with a 2 m cable drops into a standard M18 mounting hole and the pigtail reaches a remote junction box or a cordset entry on the gland plate, with the three-wire PNP NO output terminated to the PLC's sourcing input module. Flush-mount geometry means two sensors can be installed side-by-side in a flat plate without the usual spacing penalty that non-flush (shielded) M18 bodies require — useful on tight indexing or star-wheel fixture plates.
