ISE Controls in Indianapolis, Indiana has a number of products that can solve color sensing applications. Are you sorting parts by color, or looking for a registration mark on a package. We have sensors for those applications.
Color sensing is broken into color detection and Contrast detection. In color detection we are attempting to sense if a part is blue, green, yellow, or red for example. In a contrast application we are attempting to tell the difference between just 2 colors or 2 shades of the same color. Rest assured that ISE Controls will have the best product from both a performance and cost standpoint for your requirements.
