The Omron E2BM18KS05M1B1OMI is an M18 threaded-barrel inductive proximity sensor from the E2B series, delivering a 5 mm flush-mount sensing range with a PNP normally-open output. At 600 Hz switching frequency, it keeps up with fast-moving ferrous targets on a conveyor or pick-and-place station — no missed parts at cycle rates under 600 operations per second. The 10 % repeat accuracy means the switch point stays within 0.5 mm of the set position over temperature and time, deterministic enough for presence detection on a takt-timed line.
The 5 mm sensing distance is the maximum rated range when flush-mounted in steel. In a real panel or machine frame, derate for non-ferrous targets (stainless steel, aluminum) by roughly 40–60 % — a 5 mm sensor catches a steel bracket at 5 mm, but an aluminum bracket may need to pass within 2–3 mm. The 24 mm cube body (width, height) is the standard M18 barrel envelope; the 59 mm length includes the threaded barrel and the M12 connector tail. IP67 means the brass housing and connector seal against washdown spray and coolant mist — fine for machining centers or packaging lines, but not for full-pressure washdown zones (that calls for IP69K).
