The Omron E2E-X2Y1-M4 is an E2E-series inductive proximity sensor in an M12 threaded brass body with nickel plating. It's a shielded, 2-wire DC normally-open sensor with a 2 mm sensing range for ferrous metals. Supply voltage spans 24-240V DC—one part covers the full range from 24V to 240V systems—and the M12 connector saves wiring time. Rated IP67 and NEMA 4X, it resists cutting oil, so it's at home on machine tools, conveyors, or any wet line. An integral indicator light confirms target detection.
How it sits beside the larger M12-connector peer
If you're cross-shopping the E2E-X10Y1-M4 (30 mm body, 10 mm range), the difference is physical. The E2E-X2Y1-M4 fits a 12 mm hole, not a 30 mm one. It detects at 2 mm instead of 10 mm, so it's for close-proximity ferrous targets. Both use the same M12 connector and share the 24-240V DC supply, but the 30 mm version handles 300 mA load vs 200 mA here. The 12 mm version carries NEMA 4X; the 30 mm one carries NEMA 4. For a line specified around the larger sensor, the panel cutout and sensing distance must change—this isn't a drop-in swap.
Threaded barrel mounts into a 12 mm hole; shielded face allows flush mounting. Two-wire DC circuit with load current up to 200 mA and switching current 100 mA max (5 mA min), operating -40 to 185°F, with cable protector.
