Omron E2EF-QX3D1 2M Proximity Sensor
Omron E2EF-QX3D1 2M is an M12 shielded inductive proximity sensor with a 3 mm sensing distance and a 0 to 2.1 mm setting distance. It provides a DC 2-wire NO output through a pre-wired 2 m cable and operates from 10 to 30 VDC. Ferrous metal is the specified detectable object, while control output is rated from 3 to 100 mA. Red and green LEDs provide operation and setting indication, and surge suppression with load short-circuit protection is specified. The stainless-steel construction supports demanding industrial sensing environments. The E2EF-QX3D1 2M is included among all-stainless proximity sensors from Omron industrial sensing products for reliable metal detection.

The Omron E2EF-QX3D1 2M Proximity Sensor uses an M12 shielded inductive sensing body with a 3 mm sensing distance and a 0 to 2.1 mm setting distance. It provides a DC 2-wire output with NO operation through a pre-wired 2 m cable and operates from 10 to 30 VDC. Ferrous metal is the specified detectable object. Control output is rated from 3 to 100 mA. Red and green LEDs provide operation and setting indication, while surge suppression and load short-circuit protection are specified for the electrical circuit. Stainless steel SUS303 is listed for the sensor construction, together with zinc-plated iron and flame-retardant PVC. The all-stainless housing supports industrial sensing applications requiring durable construction.
Operating conditions for the E2EF-QX3D1 extend from -10 to 70°C, while storage covers -25 to 70°C without icing or condensation. IEC 60529 IP67 is the specified enclosure protection level. The shielded M12 format combines a compact 3 mm sensing distance with DC 2-wire NO switching and direct 2 m cable wiring. Separate operation and setting indicators provide visual information during sensor setup and use. The stated 3 to 100 mA control-output range supports the specified two-wire circuit configuration. For another E2EF model with the same M12 size and 3 mm sensing distance in the supplied comparison set, see E2EF-X3D1 2M.
