What is a contrast sensor?

Balluff's contrast sensors

Contrast sensors are high-resolution diffuse sensors that distinguish objects based on their gray values. Balluff's rugged contrast sensors recognize even small differences in contrast, have a high switching frequency up to 30 kHz and are therefore particularly fast. They enable high positioning precision and are appropriate for a variety of applications, for example, in the printing and packaging industry.

A variety of models with various light types and functions are available.
