Omron E3FB-LP22 Photoelectric Sensor
Omron E3FB-LP22 is a PNP background suppression photoelectric sensor intended for object sensing up to 200 mm. Its 624 nm red LED provides a visible optical source, while the BGS principle helps limit response from background surfaces outside the intended sensing zone. The sensor operates from 10 to 30 VDC and draws up to 25 mA. An M12 connector provides detachable wiring, and Light-ON or Dark-ON switching can be selected by wiring to suit the required control sequence. Response time is specified at 0.5 ms. Within the E3FB Series, the E3FB-LP22 provides the 200 mm PNP connector configuration. Applications involving background separation can explore 200 mm background suppression sensors available across Omron Sensor Range.

The Omron E3FB-LP22 Photoelectric Sensor provides background suppression sensing over a 200 mm distance referenced to white paper. A 624 nm red LED supplies the optical source, while the BGS method helps reduce response from surfaces beyond the intended target area. Its PNP output communicates the switching state to compatible industrial control circuitry. The sensor operates from 10 to 30 VDC, consumes up to 25 mA, and uses an M12 connector for detachable machine wiring. Light-ON or Dark-ON operation is selectable by wiring, and the output supports load current up to 100 mA. Response time is 0.5 ms. Orange operation and green stability indicators provide visual status, while the metal M18 body carries IP67 and IP69K environmental ratings.
For an Omron background suppression sensor requiring PNP output, 200 mm sensing, fixed sensitivity, and M12 wiring, the corresponding model is the E3FB-LP22. Its characteristics also support searches for an Omron 200 mm BGS sensor, Omron PNP photoelectric sensor, and Omron M12 background suppression sensor. For the corresponding E3FB model using the same 200 mm background suppression range and M12 connector with NPN output, see E3FB-LN22.
