Headline behaviour
The Omron E2EX16MB2L182MOMS is an E2E-Next M18 non-flush inductive proximity sensor with a PNP normally-closed output and a 2 m integral cable. Rated 16 mm nominal sensing distance with a 400 Hz switching frequency, the head can sustain high indexing rates on conveyor, indexing-drum and rotary-cam applications where inductive targets pass quickly. Loop runs on 10 to 30 V with 16 mA current draw; the PNP output sinks up to 200 mA into the load, which is enough headroom to drive a PLC sourcing input directly or a small relay coil without an interposing stage. Operating envelope covers -40 to 85 °C with IP67, IP67G and IP69K sealing, so the sensor is built for washdown cells, outdoor skids and oily-mist environments that would shorten the life of a standard IP67-only barrel.
Comparing the cable and M12 connector variants
The closest same-function sibling in the E2E-Next line is the E2EX16MB2L18M1OMS, which is identical electrically (PNP NC, 16 mm, 200 mA, IP67/IP69K, 10-30 V, -40 to 85 °C) but ships with an M12 4-pin connector and a 75 mm body length. That is the part to use when a panel was wired to an M12 drop; substituting the cable version into an M12-connector receptacle forces a re-termination, and substituting the connector version where the harness expects a flying lead forces a re-pin.
Sourcing posture
For a tender package, quote against the order code as written and request the official datasheet and declaration of conformity as supporting evidence; that paperwork is what answers compliance review without further clarification.
Buyer decision
For a sourcing buyer matching this MPN on a washdown line or outdoor skid, the IP69K rating and the -40 to 85 °C window are the fit-defining values; the PNP NC logic and the 200 mA output rating then drive the panel-side wiring decisions. Submit the order code against an RFQ and the line will be quoted to specification; the alternate M12 connector variant carries a different order code and should be substituted only when the wiring harness is being changed to match.
