What the ratings mean for fit
The Omron E2BM12LS04M1C1OMI is an M12 flush-mount inductive proximity sensor from the E2B series. Its 4 mm sensing distance means it detects ferrous targets at that range reliably — standard for a shielded M12 sensor. The NPN normally-open output pulls the load to ground when a target is present; make sure your PLC input card or relay coil is referenced to the same supply common. Switching at 1 kHz handles fast-moving parts on a conveyor or spindle — no missed counts at typical line speeds. Rated IP67 with a brass housing means this sensor handles washdown and coolant splash on a machine tool or packaging line. The M12 connector simplifies swap-out — unplug the cordset, replace the sensor, no rewiring inside the panel.
