Balluff Magnetic Sensor BKT000Y


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.
