Contrast sensors
KT8

Your Benefits

  • Versatile use for various distances from sensor to sensing object
  • Precise detection of the smallest marks and objects, e.g. 1 x 1 mm²
  • Reliable operation even in the event of object jitter
  • Access to the sensor with the controller saves the machine operator time and effort during parameterization
  • Individualized parameterization and setting specifically tailored to the application
  • Automatic drift correction enables maximum production reliability, for example in the event of weakening print marks
  • Reliable operation with high-gloss foils ensures high machine availability

Overview

The KT8 sensor family features two variants. The first variant, the KT8L, enables very reliable detection of the smallest contrast marks and objects thanks to the precise laser. Lasers are used in contrast sensors for long sensing distances (up to 800 mm) or for detecting very small objects. The KT8L gives you both! Thanks to the two light spot sizes, the smallest elements can be detected with < 0.3 mm and larger objects and marks with approx. 3 mm. 3-color LED, gloss adjustment, automatic drift correction and short response times are what make this device the ideal product.
