Color & contrast sensors
The attachment of color marks that are then evaluated with a color or contrast sensor is a proven method for identifying objects in industrial production. Even objects with differing shapes and surface properties can be very reliably detected in this way.

Color sensors

  • Sorting packaging or checking different labels
  • Detecting colors and color ranges on packaging and film


Contrast sensors

  • Detecting printing marks with the subtlest variations in grey values in the printing and packaging industry
  • Checking labels and stickers in the printing industry


Luminescence sensors

  • Detecting labels on glass bottles
  • Detecting invisible printing marks for object alignment


Reliable detection and differentiation of colors
Differences in color and contrast are important characteristics for the detection and differentiation of objects. Sensors from SensoPart reliably detect colored objects, prints and labels during production processes or quality assurance.  

Our color and contrast sensors are suitable for almost every relevant automation task thanks to precise color evaluation and rapid cycle times. The compact FT 55-CM color sensor is particularly versatile, offering outstanding color detection and sorting even with challenging surfaces. Our portfolio also includes sensors suitable for special tasks, such as the identification of invisible, luminescent color markings. Our vision color sensors from the VISOR® Color series fulfil the highest requirements in terms of color detection. They offer very high color selectivity and can also detect active (self-illuminating) colors.
