The KT10 from SICK Optic-Electronic (Bloomington, MN) is a 10-color contrast sensor that is said to read any contrast in color 25ꯠ times/sec. The operator pushes a button to "teach" the sensor, which then "looks" at the contrast it is required to sense and selects the proper light source for best results.
