Omron E3FB-DP11 2M Photoelectric Sensor
Omron E3FB-DP11 2M is a PNP diffuse-reflective photoelectric sensor for sensing objects across a specified 100 mm distance referenced to white paper measuring 300 × 300 mm. Its 624 nm red LED provides a visible sensing source, while a one-turn adjuster supports sensitivity setting. The sensor operates from 10 to 30 VDC and includes a pre-wired 2 m cable for direct electrical connection. Light-ON or Dark-ON operation can be selected by wiring, and response time is 0.5 ms. Orange operation and green stability indicators assist during setup and operation. Within the E3FB Series, the E3FB-DP11 2M provides the short-range PNP cable configuration. Compact machine applications can use PNP diffuse photoelectric sensors across Omron Industrial Products.

The Omron E3FB-DP11 2M Photoelectric Sensor uses diffuse-reflective sensing across a specified 100 mm distance referenced to white paper measuring 300 × 300 mm. A 624 nm red LED directs light toward the target and evaluates the returned signal without requiring a reflector. Its PNP output interfaces with compatible PLC inputs and machine-control circuitry, while Light-ON or Dark-ON operation is selectable by wiring. The sensor operates from 10 to 30 VDC and consumes 25 mA max. A pre-wired 2 m cable provides direct electrical connection. Response time is specified at 0.5 ms, and a one-turn adjuster supports sensitivity setting. Orange operation and green stability indicators provide visual status during adjustment. Power-supply reverse polarity, output short-circuit, and output reverse-polarity protection are included in the listed electrical protection functions.
For an Omron PNP diffuse photoelectric sensor requiring 100 mm sensing and fixed cable wiring, the relevant model is the E3FB-DP11. Operating temperature extends from -25 to 55°C, with storage from -40 to 70°C under the stated conditions. IP67 and IP69K enclosure ratings are listed, and nickel-brass, PMMA, and POM are among the specified materials. Its specification also suits searches for an Omron 100 mm PNP sensor, Omron pre-wired photoelectric sensor, and Omron M18 diffuse sensor. For the related PNP E3FB version with the same 100 mm sensing distance and an M12 connector, see E3FB-DP21.
