Energetic
The energetic photoelectric proximity sensor with adjustable sensitivity is the simplest photoelectric proximity sensor variant. A light-colored surface reflects more light than a dark one, and can therefore be detected at a greater distance. Detecting a dark object against a light background is a challenge for energetic sensors. The object is obscured by the brighter background due to its higher reflectivity. Light-colored objects against dark backgrounds are easier to detect.
