The Omron E2E-X8MD1 5M is an inductive proximity switch from the E2E series, unshielded, with an 8 mm sensing range, DC 2-wire normally open output, and a 5-meter PVC cable.
Detect metal targets without contact. Unshielded design with 8 mm range, DC 2-wire output.
How it compares to a common peer
You'll sometimes see the E2KQ-X10ME1 in the same category, but that's a capacitive sensor—it picks up non-metals too. It runs NPN-NO 3-wire and needs a 10–30 VDC supply, while this E2E-X8MD1 5M is purely inductive, 2-wire. Different output type means you can't just swap the part without rewiring the input card. Stick with this if you only want metal detection and want to keep the wiring simple.
