The Omron E2BM12LS04M1B1OMI is a flush-mount M12 inductive proximity sensor from the E2B series, delivering a 4 mm sensing distance with a PNP normally-open output. It switches at up to 1 kHz, so it handles fast-moving ferrous targets on a conveyor or indexing station without missing counts. The 17 mm body width and M12 quick-disconnect (4-pin) make it a drop-in replacement for standard M12 barrel sensors in tooling or packaging lines.
What the ratings mean for fit
The 4 mm flush-mount sensing range means the sensor face can be level with the mounting surface and still detect steel targets up to that distance — critical when space is tight and you can't have a protruding barrel. The PNP normally-open output (sinking 200 mA max) is the standard signal for PLC digital inputs that expect a positive voltage when the target is present. IP67 sealing means the sensor body and connector withstand washdown and coolant splash, so it's fine on a machining center or a food-grade conveyor that gets hosed down.
