Omron E2E-X3B28-M3 Proximity Sensor
Omron E2E-X3B28-M3 uses an M8 shielded short-body housing with 3 mm sensing and DC 3-wire PNP normally closed operation. Wiring is provided through an M8 4-pin connector, while its setting range extends from 0 to 2.4 mm. The sensor accepts 10 to 30 VDC and operates at a 1,000 Hz response frequency. The E2E-X3B28-M3 sits within the E2E NEXT Series, with similar compact models available through the complete M8 inductive sensor selection offered among automation sensing products from Omron Sensors.

The Omron E2E-X3B28-M3 Proximity Sensor has an M8 shielded short-body format with a 3 mm sensing distance and 0 to 2.4 mm setting range. DC 3-wire PNP normally closed switching is connected through an M8 4-pin connector. Operating voltage spans 10 to 30 VDC, and response frequency reaches 1,000 Hz. Ferrous metals are specified using an iron 9 × 9 × 1 mm standard object. Rated current is 100 mA max. for the listed 1-output model. Reverse supply polarity, reverse output polarity, surge, and short-circuit protection are specified.
For compact mounting that requires an Omron M8 proximity sensor with four-pin connection and PNP NC logic, the matching model is the E2E-X3B28-M3. Operating and storage temperatures range from -25 to 70°C, together with IP67 under IEC 60529 and ISO 20653. Nickel-plated brass, PBT, zinc-plated iron, and PVC are included in the material specification.
