ABOUT COLOR SENSORS

The CSM 1, CS 1, CS 3 color sensors are small, compact and powerful for color detection of either opaque or transparenttargets. Consequently, these can be used for the automation of all industrial processes where color is a factor.

These sensors use three colored LEDs simultaneously as their light source and evaluate both the wavelength and amount of reflected light. The measured values are compared with stored reference color values that the operator enters using a simple teach-in process. If the values are within the defined tolerance, the sensor produces an output. Depending on the application, one or three reference colors can be taught and stored by the sensor. Color sensors are also extremely insensitive to ambient light sources.
