Omron E3FB-DN11 2M Photoelectric Sensor
Omron E3FB-DN11 2M is an NPN diffuse-reflective photoelectric sensor for short-range object sensing up to 100 mm. Its red LED illuminates the target and evaluates the returned light directly, removing the need for a separate reflector or receiving unit. The sensor operates from 10 to 30 VDC and includes a pre-wired 2 m cable for direct connection to control wiring. Light-ON or Dark-ON operation can be selected according to the machine sequence, while a 0.5 ms response supports fast switching. The M18 cylindrical body is made from nickel-plated brass and measures 44 mm in length. Within the E3FB Series, the E3FB-DN11 2M provides the short-range cable configuration. Compact sensing points can use 100 mm diffuse photoelectric sensors from Omron Industrial Sensors.

The Omron E3FB-DN11 2M Photoelectric Sensor uses diffuse-reflective sensing for object sensing across a specified 100 mm distance. Its red LED directs light toward the target, and the sensor evaluates the returned light directly without requiring a separate reflector or receiving unit. The NPN output communicates the switching state to compatible PLC inputs and machine-control circuitry. Light-ON or Dark-ON operation can be selected according to the required sequence. Operating voltage is 10 to 30 VDC, current consumption is 25 mA max., and a pre-wired 2 m cable provides the electrical connection. Response time is specified at 0.5 ms. The M18 threaded cylindrical housing is made from nickel-plated brass and measures 44 mm in length. IP67 and IP69K enclosure ratings are listed for the sensing body.
For an Omron diffuse-reflective photoelectric sensor requiring NPN output, 100 mm sensing, and fixed cable wiring, the corresponding model is the E3FB-DN11. Direct reflection from the target allows installation without an additional optical unit, while selectable operating mode helps match the switching state to the control requirement. Its characteristics also suit searches for an Omron NPN photoelectric sensor, Omron 100 mm diffuse sensor, and Omron pre-wired photoelectric sensor. For the related NPN model offering the same 100 mm sensing distance with an M12 connector instead of a fixed cable, see E3FB-DN21.
