Omron E3FB-DP23 Photoelectric Sensor
Omron E3FB-DP23 is a PNP diffuse-reflective photoelectric sensor created for direct object sensing up to 1 m using a 624 nm red LED. Its M18 metal body houses the optical system, while an M12 connector provides detachable wiring for machine installation and servicing. The unit operates from 10 to 30 VDC, consumes up to 25 mA, and supports selectable Light-ON or Dark-ON operation by wiring. A one-turn adjuster supports sensitivity setting, and response time is specified at 0.5 ms. Within the E3FB Series, the E3FB-DP23 represents the long-range PNP connector model. Applications requiring removable wiring can explore M12 diffuse photoelectric sensors across Omron Automation Sensors.

The Omron E3FB-DP23 Photoelectric Sensor uses diffuse-reflective sensing with a maximum 1 m range referenced to a white target. Its 624 nm red LED provides visible sensing light, while the PNP output transfers the switching state to compatible machine-control circuitry. Operating voltage is 10 to 30 VDC, and current consumption is specified at 25 mA max. The M12 connector provides detachable wiring, while a one-turn adjuster supports sensitivity setting according to target reflectivity and distance. Light-ON or Dark-ON operation is selectable by wiring. Response time is 0.5 ms, and orange operation plus green stability indicators provide visual status. The metal M18 housing carries IP67 and IP69K environmental ratings.
For an Omron 1 m diffuse photoelectric sensor requiring PNP output, adjustable sensitivity, and M12 connector wiring, the relevant model is the E3FB-DP23. Its configuration also fits searches for an Omron M12 photoelectric sensor, Omron PNP diffuse sensor, and Omron long-range diffuse sensor. For the corresponding PNP E3FB model using the same 1 m diffuse sensing range with a pre-wired 2 m cable, see E3FB-DP13 2M.
