Omron E2E-X3C18-M3 Proximity Sensor
Omron E2E-X3C18-M3 provides 3 mm sensing in an M8 shielded short-body design with DC 3-wire NPN normally open output. An M8 4-pin connector supports removable wiring, and the specified setting range extends from 0 to 2.4 mm. Supply voltage is 10 to 30 VDC with a 1,000 Hz response frequency. The E2E-X3C18-M3 belongs to the E2E NEXT Series, while similar connector models can be explored through the wider 3 mm proximity sensor range available among sensing products from Omron Sensors.

The Omron E2E-X3C18-M3 Proximity Sensor provides 3 mm sensing from an M8 shielded short-body construction with a 0 to 2.4 mm setting range. Its DC 3-wire NPN output operates as normally open through an M8 4-pin connector. The unit runs from 10 to 30 VDC at a 1,000 Hz response frequency. Ferrous metals are specified using an iron 9 × 9 × 1 mm standard object. Output current is rated at 100 mA max. for the listed configuration. Reverse polarity, surge, and output short-circuit protection are specified.
When an Omron M8 proximity sensor needs NPN NO operation with compact four-pin wiring, the applicable model is the E2E-X3C18-M3. Temperature limits for operation and storage are -25 to 70°C, together with IP67 according to IEC 60529 and ISO 20653. Nickel-plated brass, PBT, zinc-plated iron, and PVC are included among the construction materials. This version supports searches for an Omron NPN proximity sensor, Omron shielded proximity sensor, and Omron 3 mm proximity sensor. For an M12 PNP model with 8 mm sensing, see E2E-X8MB1D12-M1.
