Contrast sensors are high-resolution light sensors that differentiate objects according to their gray values. The robust contrast sensors from Balluff detect even small contrast differences, have a high switching frequency of up to 30 kHz and are therefore particularly fast. They enable high positioning accuracy and are therefore suitable for a wide range of applications, for example in the printing and packaging industries.
