Our Background Suppression Photoelectric Sensors are suitable for applications that require the sensor to detect objects in close proximity to backgrounds with reflective properties. This is useful when the target and background have similar reflectivities (e.g., the reflectivity of light returning to the sensor from the target is approximately equal to the reflectivity of light reflecting off the background), or when a darker target is to be detected against a brighter, more reflective background. This background suppression is particularly effective.
