E3FA-DP11 Safety Light Curtain | F3SJ Series Industrial Safety Sensor

The Omron E3FA-DP11 is a compact, M18 threaded cylindrical photoelectric sensor from Omron’s E3FA Series . It utilizes a diffuse-reflective (also known as proximity) sensing method, where the emitter and receiver are housed together, and detection occurs when light reflects off the target object directly back to the sensor .
