Omron E2E-X18ME1-M1 Inductive Proximity, 18mm, NPN-NO

The Omron E2E-X18ME1-M1 is an unshielded inductive proximity sensor that switches at 18 mm – that's the actual detection distance, not the mounting range. Because it's unshielded, you can't bury it in a metal bracket; you need that full 18 mm of clearance to the target and any surrounding steel. The output is NPN normally open, 3-wire DC, terminated in an M12 connector. That M12 makes this a quick field swap: unplug the old sensor, plug this in, no re-termination needed. It'll mate with most standard M12 pigtails already on the machine.
