Sensor facts for the BOM line
The Omron E2E2-X5Y1 is a shielded M18 inductive proximity sensor switching 20-264V AC loads up to 300 mA, NO contact, 2-wire AC. Prewired with 2 m cable, bare wire ends. Rated IP67 and NEMA 1, 3, 4, 6, 12, 13 — fits washdown zones and outdoor cabinets. Brass body, nickel-plated, with cable protector and milled wrench flats.
Storeroom stand-in check: E2E2-X5Y1 vs. E2E2-X5Y1-US
The US variant (E2E2-X5Y1-US) shares the same M18 shielded body, 5 mm sensing distance, and 20-264V AC 2-wire output. It ships with mounting hardware, but its temperature range is -13°F to 158°F vs. the -40°F to 185°F on the standard Y1. If your panel sees freezer temps or outdoor cold snaps, keep the standard Y1 on the shelf — the US one won't hold at -40°F. For a NC-output replacement, use E2E2-X5Y2 — same form, same wiring, normally closed contact.
Lifecycle and compliance — active, standard item
Carries CCC and CE markings. For other compliance documentation (RoHS, REACH, UL) beyond the listed standards, request the manufacturer's declaration against your specific order.
Mounting and wiring notes
M18 threaded barrel, shielded face — mounts flush in steel. 2 m prewired cable, bare wire ends, 2-wire AC. No polarity on AC but watch load current stays between 5 mA minimum and 300 mA maximum. Nickel-plated brass body resists corrosion in wet or washdown areas. Use the milled section for a wrench to tighten without damaging the threads.
