Omron's E2E-X5MY2 2M is an industrial inductive proximity switch in the E2E standard series. It provides a normally closed output over an AC 2-wire circuit, sensing ferrous metals at 5 mm through an unshielded face. The attached 2-metre PVC cable simplifies installation in control panels and conveyor lines where a compact, fixed-cable sensor is preferred.
AC 2-wire vs DC 3-wire peer
The closest peer by sensing distance and unshielded construction is the E2E-X5MF1-M1, but that sensor uses a DC 3-wire PNP output with an M12 connector. Dropping this AC 2-wire NC unit into a panel wired for a DC 3-wire NO sensor means rewiring the supply and confirming the load switching logic. The cable exit and mounting dimensions are shared, so the physical fit is the same; the electrical footprint is not.
