The Omron E2EX2Y12MOMS is a flush-mount M12 inductive proximity sensor that makes contact when it sees ferrous metal within 2 mm. Rated across 20–264 VAC/DC, it handles a 200 mA load and switches at 25 Hz—fast enough for pitch-position feedback or blade-pitch limit stops up-tower. Operating temperature range -40 to 85°C. Repeat accuracy 10% holds across the full range.
How it compares to the NC counterpart (E2EX2Y22MOMS)
Same housing: 21 mm square, 43 mm deep, M12 brass barrel, same flush mount, same 2 m cable, same 2 mm sensing distance. The critical difference is output logic: this one goes to NO (make on target), the E2EX2Y22MOMS is NC (break on target). If your panel was wired for an NC prox (e.g., safety-circuit series chain), dropping in this NO sensor means rewiring the load or inverting the PLC input logic. Also note the temperature range: this one handles -40 to 85°C while the NC peer only covers -25 to 70°C—a real difference if you're mounting on a nacelle roof exposed to low extremes.
