Colour Sensors

Wenglor Color Sensors differentiate amongst the finest of color nuances faster and more accurately than the human eye. They reliably select colored objects in automated high-speed processes based on previously defined reference colors. The sensors' pulsed white light is insensitive against extraneous light and makes reliable color recognition possible even with a fluctuating scanning distance. Their diverse range of possible applications, for example in the automotive, packaging, textil and printing industries, make them a valuable tool for inline quality assurance.

The spectral composition of the colors of objects can be measured and metamerism effects can be compensated for with the P1XF001 6-channel multispectral sensor. Innovative color chip technology divides the selected color spectrum into six spectral ranges (ROYGBV color space: Red, Orange, Yellow, Green, Blue, Violet) with separately adjustable tolerance ranges. In combination with fiber-optic cables, the sensor adapts itself to the specific requirements of any given application and can be operated in the scanning as well as the through-beam mode. The P1XF001 is equipped with twelve switching outputs and integrated LED technology, which automatically ensures ideal adjustment of light intensity. Sensor settings can be selected directly at the graphical display (OLED), via the RS-232 port or via the IO-Link interface.

The OFP401P0189 True Color Sensor detects the finest of color nuances despite distance changes of up to 10 mm. Three colors can be taught in simultaneously and read out as RGB or HSL color values via the RS-232 port. With its single-lens optics, the sensor accurately detects objects over large working ranges. Settings can be configured conveniently via the teach-in function or with Teach2 software.

Application examples:

  • Detection of color markings on print marks, labels and packages
  • Sorting of objects according to color
  • LED function control
  • Checking of Color values for painting operations
  • Monitoring of degrees of ripeness for fruit
  • Spectral measurement of colors in printing processes
