The color sensors of SI-COLO Series operate according to the 3-color-range principle, with a white-light LED as a light source.
Except of the sensors of SI-COLO1 series, the color sensors can be parameterized under Windows? through the serial RS232 interface.
With the SPECTRO-3 series there now is a family of color sensors that has been specifically designed for "true-color" detection ("human color reception") and high switching frequency.
The sensors can be operated both in AC and in DC mode, with integrated or external light source. With the included SPECTRO3-Scope software illumination can also be turned off with a simple mouse-click, which then also allows the color and brightness inspection of self-luminous objects such as LEDs, automobile tail lights, halogen lamps, or fluorescent lamps.
