The Omron E2E-X5Y1-US 2M is a shielded proximity switch with a 5 mm sensing distance, normally open output, and AC 2-wire operation. It comes with a 2-meter PVC cable and carries UL certification.
This AC 2-wire variant sits apart from DC 3-wire siblings like the E2E-X1R5E1-M1 (1.5 mm, NPN, M12 connector) and E2E-X5MF1-M1 (5 mm, PNP, unshielded). The sensing distance matches the E2E-X5MF1-M1, but the AC output and shielded construction mean a direct swap requires rewiring and power supply changes.
