Omron E2E-X2Y1 is a shielded M12 threaded inductive proximity sensor with a 2 mm sensing distance, designed for ferrous metal detection in environments where cutting oil is present. It operates on 20-264V AC, 2-wire, normally open output, drawing a load current from 5 mA up to 200 mA per the listed ratings. The brass housing with nickel plating carries an IP67 and NEMA 1, 3, 4, 6, 12, 13 ingress rating, and the 2 m bare-wire cable includes a cable protector.
DC sibling delta
The E2E-X2Y1-M4 shares the same 2 mm shielded sensing distance, M12 thread, and mechanical dimensions as this AC part but uses a DC output circuit (24-240V DC) with an M12 connector instead of a 2 m cable. The output type is the critical difference: the -M4 is DC-type, while the -X2Y1 is AC-type. A panel wired for AC 2-wire sensing will not communicate with a DC output without rewiring the sensor supply and loading.
Sourcing
This part is listed as current production, so standard OEM sourcing applies. It can be specified into a BOM line on that basis. The 2-wire AC output and wide voltage range (20-264V AC) make it a direct-fit replacement for original equipment using that same sensor code.
