The Omron E2SW251MOMS is a square-body inductive proximity sensor from the E2S series, rated IP67 and built with a polyarylate resin housing that holds up to washdown environments in packaging and filling lines. It switches make-contact (NO) at up to 1 kHz, delivers 50 mA load current, and draws 13 mA from a 10–30 V supply. The 2.5 mm sensing distance covers close-proximity metal target detection, and the pre-wired termination saves a connector in tight gland plates.

Frequently asked questions
What are the key dimensions of E2SW251MOMS?
Width 8 mm, height 7.4 mm, length 20 mm. The square through-hole body requires a clearance hole and nut for mounting.
Can the E2SW251MOMS replace the E2SW211MOMS in an existing panel?
Not without changes. The E2SW211MOMS uses non-flush bracket mounting, while the E2SW251MOMS requires a through-hole panel cutout. The pre-wired termination also differs from the peer's 1 m cable. Rewiring and mounting hardware adjustments are needed.
