Omron E3FB-DP12 2M Photoelectric Sensor
Omron E3FB-DP12 2M is a PNP diffuse-reflective photoelectric sensor with a specified sensing distance of 300 mm and a pre-wired 2 m cable. Its red LED sends light toward the target and evaluates the returned signal directly, so no separate reflector is required. The sensor operates from 10 to 30 VDC and consumes 25 mA max. Light-ON or Dark-ON operation can be selected to suit different machine sequences, while response time is specified at 0.5 ms. The M18 cylindrical housing uses nickel-plated brass and measures 44 mm in length. Within the E3FB Series, the E3FB-DP12 2M provides the 300 mm PNP cable option. Medium short-range applications can explore 300 mm PNP photoelectric sensors available through the Omron Sensing Range.

The Omron E3FB-DP12 2M Photoelectric Sensor uses diffuse-reflective sensing for object sensing across a specified 300 mm distance. Its red LED sends light toward the target, and the returned optical signal is evaluated directly without requiring a separate reflector or receiving unit. The PNP output transfers the switching state to compatible PLC inputs and industrial control circuitry. Light-ON or Dark-ON operation can be selected according to the required machine logic. Operating voltage is 10 to 30 VDC, current consumption is 25 mA max., and a pre-wired 2 m cable provides direct electrical connection. Response time is specified at 0.5 ms. The cylindrical axial body uses an M18 threaded arrangement, is made from nickel-plated brass, and measures 44 mm in length. IP67 and IP69K enclosure ratings are listed for the sensor.
For an Omron 300 mm PNP photoelectric sensor requiring diffuse sensing and fixed cable wiring, the corresponding model is the E3FB-DP12. The 300 mm sensing distance extends beyond the shorter DP11 version while retaining the same PNP pre-wired arrangement. A visible red LED assists during sensor positioning, and selectable Light-ON or Dark-ON operation lets the switching state follow different control requirements. The model also matches searches for an Omron PNP diffuse sensor and Omron M18 photoelectric sensor. For the corresponding PNP E3FB model using the same 300 mm sensing distance with detachable M12 connector wiring, see E3FB-DP22.
