Contrast Sensor

  • For mark detection in printing
  • High switching frequency, 10KHZ
  • 2 Push-pull complementary output
  • Rotatable Metal connector M12

When a contrast sensor passes the taught-in point between the background and print mark, it quickly recognizes it and indicates the exact position of the mark. These sensors are used for precise object positioning in printing machines, packaging plants, and labeling machines in the food, beverage, and pharmaceutical industries. They are characterized by a low contrast resolution, a high degree of switching reliability when differences in contrast are minimal, short response times, and insensitivity to fluctuations in height and angle on the material web.
