Omron E2E-X4MC28-M3 Proximity Sensor
Omron E2E-X4MC28-M3 uses an M8 unshielded short-body housing with a 4 mm sensing distance and DC 3-wire NPN normally closed output. Its setting range covers 0 to 3.2 mm, and an M8 4-pin connector supports detachable wiring. The sensor operates from 10 to 30 VDC at a 1,000 Hz response frequency. The E2E-X4MC28-M3 belongs to the E2E NEXT Series, while other compact NPN versions can be explored through the wider M8 proximity sensor range available among products from Omron Sensors.

The Omron E2E-X4MC28-M3 Proximity Sensor uses an M8 unshielded short-body housing with a 4 mm sensing distance and setting range from 0 to 3.2 mm. Its DC 3-wire NPN output operates as normally closed through an M8 4-pin connector. The sensor accepts 10 to 30 VDC and operates at 1,000 Hz. Ferrous metals are specified using an iron 12 × 12 × 1 mm standard object. Rated current reaches 200 mA max. for 1-output models and 50 mA max. for 2-output models. Supply polarity, output polarity, surge, and short-circuit protection are specified.
For an Omron M8 proximity sensor requiring compact mounting, NPN NC switching, and four-pin connection, the corresponding model is the E2E-X4MC28-M3. Operating and storage temperatures cover -40 to 85°C, together with IEC 60529 IP67 and ISO 20653. Stainless SUS303, PBT, nickel-plated brass, zinc-plated iron, and PVC are listed among the construction materials. This model also supports an Omron NPN proximity sensor, Omron 4 mm proximity sensor, and Omron unshielded proximity sensor. For a related M8 unshielded short-body NPN NC model with a 3-pin connector, see E2E-X4MC28-M5.
