Omron E3FB-DN12 2M Photoelectric Sensor
Omron E3FB-DN12 2M is an NPN diffuse-reflective photoelectric sensor with a specified 300 mm sensing distance and a pre-wired 2 m cable. A red LED provides the optical source, allowing the sensor to respond to light returned directly from the target without requiring another optical unit. It operates from 10 to 30 VDC with current consumption of 25 mA max. Light-ON or Dark-ON operation can be selected, and response time is specified at 0.5 ms. The cylindrical M18 housing uses nickel-plated brass and has a stated length of 44 mm. Within the E3FB Series, the E3FB-DN12 2M provides the 300 mm NPN cable option. Medium short-range applications can use 300 mm diffuse photoelectric sensors across Omron Automation Sensors.

The Omron E3FB-DN12 2M Photoelectric Sensor uses diffuse-reflective sensing across a specified 300 mm distance with a red LED as the optical source. Light is directed toward the target and evaluated after reflection, allowing object sensing without a separate reflector or receiving unit. The NPN output provides the switching state to compatible PLC inputs and industrial control circuitry. Light-ON or Dark-ON operation can be selected to follow the required machine sequence. The sensor operates from 10 to 30 VDC, consumes 25 mA max., and includes a pre-wired 2 m cable for direct connection. Response time is specified at 0.5 ms. Its M18 cylindrical axial housing uses nickel-plated brass, measures 44 mm in length, and carries IP67 and IP69K enclosure ratings for use under the stated environmental conditions.
For an Omron 300 mm diffuse photoelectric sensor requiring NPN output and fixed cable wiring, the relevant model is the E3FB-DN12. The 300 mm range extends direct target sensing beyond the shorter 100 mm version while retaining the same general M18 cable format. A visible red LED assists with positioning, and selectable Light-ON or Dark-ON operation provides flexibility when integrating the sensor with machine logic. The specification also suits searches for an Omron NPN diffuse sensor and Omron M18 photoelectric sensor. For the corresponding NPN E3FB model with the same 300 mm sensing distance and detachable M12 connector, see E3FB-DN22.
