What this sensor is and where it fits
The Omron E2EX3D28T2MOMS is a current-production M8 inductive proximity sensor from the E2E NEXT series. It detects ferrous targets at 3 mm range when flush-mounted in metal, and switches a normally-closed (NC) load at up to 350 Hz. The 2 m flying lead comes pre-wired, saving a connector. Rated 10–30 VDC, 100 mA max load current, IP67 — ready for coolant splash exposure on a machine tool. The NC output opens when a target is present. Verify load within 100 mA and supply 10–30 VDC.
How it compares to similar sensors your BOM might call out
The M12 peer E2EX7D2122MOMS is not a cable-swap replacement. It has a 21 mm hex body vs this unit's 15 mm, and a longer 47 mm can, so it won't drop into the same M8 clearance hole or bracket pocket. It also senses 7 mm instead of 3 mm, which changes target standoff. If the panel is already drilled for M8, you'd need a new sensor holder and possibly a different target cam. The output polarity is the same NC, but the mechanical delta rules out a straight substitution.
Lifecycle and sourcing posture
For compliance documentation, the E2E NEXT series typically carries RoHS and REACH declarations from Omron. If your incoming quality team needs the specific declaration of conformity or a CE certificate, request it with your RFQ — the sensor itself is marked with the relevant approvals per Omron's standard label.
What to watch during installation
The M8 threaded barrel is flush-mount rated, so you can thread it into a tapped hole in steel without derating the sensing distance — that 3 mm is real against an iron target, not a derated figure. Torque to about 10 N·m; the brass housing will strip if over-tightened. Keep the 2 m cable clear of high-frequency inverter bundles; the sensor itself switches at 350 Hz, but the cable isn't shielded, so route it separately from VFD output lines. At 15 mm wide, it fits in a standard M8 clamp. If you're populating a row of sensors, center-to-center spacing should be at least 30 mm to avoid mutual interference when flush-mounted. The IP67 seal is good for washdown but the cable entry should be pointed downward to avoid water pooling at the gland.
