WebJun 21, 2024 · Photoelectric Sensors are used in the automotive, food, transportation, and material handling industries to name a few. They c an be used to detect most materials … WebThis background suppression is particularly effective when the target and background have similar reflectivity (for example, light returned to the sensor from the target is roughly equal to the light reflecting from the background) or when dark targets are to be sensed against a lighter, more reflective background.
