The Omron E2BM18KN16WPB12MOMI is an M18 inductive proximity sensor from the E2B series, offering a 16 mm sensing distance in a non-flush mount configuration. It switches PNP normally open (NO) at up to 400 Hz, making it a solid choice for detecting ferrous targets through a non-metallic window or at a standoff. The 10-30 VDC supply range and 200 mA load current cover standard 24 VDC control circuits without extra conditioning.
What the ratings mean for fit
The 16 mm sensing distance is the key number: it's the maximum rated detection range for a mild steel target, and it's achieved only with non-flush mounting (the sensor face extends past the surrounding metal). That means you need clearance around the barrel — about 3× the diameter (54 mm) of free space in the mounting surface to avoid derating the range. The brass nickel-plated barrel and IP67 rating let it handle washdown and coolant splash on machine tools or conveyor lines, though the pre-wired cable (2 m, typically) means you're committing to a fixed lead length rather than a quick-disconnect connector.
