The Omron E2EX12B218M1OMS is an M18 flush-mount inductive proximity sensor from the E2E-X series, delivering a 12 mm sensing distance with a normally closed (NC) output. Rated IP67 and IP69K, it handles washdown environments without sealing concern. The nickel-plated brass housing and M12 connector make it a straightforward swap on existing M18 mounting points.
Flush-mount installation in metal uses a standard M18 hole and 29 mm hex body; the M12 connector mates with standard cordsets. Verify pin assignment for NC output and note the 500 Hz switching frequency for high-speed counting. Operating range is 10–30 VDC, current consumption 20 mA, load current max 50 mA. If driving a PLC input, confirm the sink capacity – the NC output sources current when open, which some sinking cards interpret as 'off'. A quick field wiring check before final tie-wrap avoids the common 'dead sensor on arrival' call.
