Omron E3FB-LP11 2M Photoelectric Sensor
Omron E3FB-LP11 2M is a PNP background suppression photoelectric sensor with a 100 mm sensing distance and a pre-wired 2 m cable. Its BGS optical principle focuses on objects inside the intended sensing zone while helping reduce influence from surfaces positioned farther behind the target. A red LED provides the light source, and the sensor operates from 10 to 30 VDC. The M18 cylindrical axial body supports threaded mounting, while selectable Light-ON and Dark-ON operation allows the output response to suit the machine sequence. Response time is specified at 0.5 ms. Within the E3FB Series, the E3FB-LP11 2M provides the pre-wired PNP format. Short-range BGS applications can explore 100 mm background suppression sensors offered through Omron Industrial Sensor Products.

The Omron E3FB-LP11 2M Photoelectric Sensor uses background suppression sensing with a 100 mm range, helping the sensor respond to the intended target while reducing influence from surfaces behind the selected sensing area. A red LED supplies the optical source, and the PNP output provides the switching signal to compatible PLC inputs. The sensor operates from 10 to 30 VDC and includes a pre-wired 2 m cable for fixed electrical connection. Current consumption is specified at 25 mA max. Selectable Light-ON or Dark-ON operation allows the output state to match the control sequence, while the 0.5 ms response time supports moving parts. The M18 cylindrical axial housing uses nickel-plated brass and carries IP67 and IP69K ratings.
For an Omron PNP background suppression sensor requiring 100 mm sensing, fixed cable wiring, and threaded M18 mounting, the relevant model is the E3FB-LP11. Its configuration also matches searches for an Omron 100 mm BGS sensor, Omron pre-wired photoelectric sensor, and Omron PNP background suppression sensor. For the corresponding PNP E3FB model using the same 100 mm background suppression range with an M12 connector, see E3FB-LP21.
