The Omron E2BM12LS02WPB12MOMI is a M12 inductive proximity sensor from the E2B series, with a 2 mm flush-mount sensing distance and a PNP normally-open output. That 2 mm range means it detects ferrous metal targets at a consistent standoff — useful for cam detection or end-of-stroke sensing on a pneumatic cylinder where the target passes close. The PNP NO output sinks 200 mA, so it drives a PLC input or a small relay directly without an interposing module. The 1.5 kHz switching frequency handles fast-moving parts on a pick-and-place or a conveyor index. The brass housing with an IP67 rating means this sensor stands up to coolant splash and washdown on a machining center or a packaging line. I've buried plenty of those in the grease and grime of a real rotating-equipment route, and the brass body takes the abuse better than plastic. The 2 m cable exits the back, so you run it straight into a junction box or a quick-disconnect fitting without extra pigtails.
The part carries a 10 mA current consumption from the 10–30 VDC supply, so it's light on the power budget in a multi-sensor panel. The repeat accuracy of 10 % means the sensing point shifts up to 0.2 mm over temperature and time — fine for presence detection, not for precision gaging.
