The colorSENSOR CFO100 is a new sensor for precise color recognition for industrial measurement tasks. The controller is distinguished by high color accuracy, state-of-the-art interfaces and intuitive operation. Fiber optics which can be adapted for various measuring tasks, are connect- ted to the controller. Using a modulated high-power white light LED, a white light spot is pro- ejected via the fiber optics onto the surface to be detected. Part of the light that is back scattered from the target is directed onto a perceptive True Color detector via the same fiber optics, separated into long-, medium- and short-wave light components (X=long, Y=medium, Z=short) and transformed into L*a*b* color values. Intuitive key operation enables the user to easily teach-in up to 256 colors in 6 color groups. One function alone adapts the illumination, averaging and signal amplification to the current measurement situation. Furthermore, tolerance models and tolerance values can be adjusted individually. If the sensor recognizes one of the taught colors, the switching state changes via three digital outputs. Binary output switching provides cable breakage protection and enables output of up to 6 color groups. Equipped with optical fibers, the sensor can also be used in restricted areas as the sensor head requires a minimum of space.
