High response sensitivity and contamination compensation

A classic example of the use of high-performance photoelectric sensors are car wash lines or so-called gantry car washes. In particular, the main cleaning brushes and dryer fans of such systems, which travel over the car body during cleaning and drying, require a sensitive light barrier that is also capable of detecting vehicle glass (e.g. front and rear windows) in order to control the corresponding pressure of the brushes or the distance of the dryer fan according to the vehicle contours. In addition, the brushes for the wheel rims can also be controlled via a light barrier.
