Foreground suppression

Photoelectric proximity sensors with foreground suppression are able to detect objects at a defined sensing range.

All objects between the sensing range (set to the background) and the sensor are detected.

To ensure that these sensors function reliably, the background (for example, a conveyor belt) needs to be relatively light and should not vary in height. Photoelectric proximity sensors with foreground suppression are particularly well-suited for detecting dark and very shiny objects.
