SICK offers its line of CVS Color Vision Sensors that include the industry's first true optical character recognition sensor (OCR.)
CVS family includes four color vision sensor solutions: the CVS1 Easy, CVS2, CVS3, and the CVS4. The CVS1 Easy allows the user to detect and distinguish between up to eight customer-selected colors. The teaching procedure is simple, making it very user friendly. The CVS2 extends the capability of the CVS1 Easy. It allows the user to detect and sort between 15 customer-defined colors. Sensor also has two switching output connections, allowing for up to three colors to be detected using only digital I/O. The CVS3 searches the field of view for the shape or contour that the user teaches. It can store up to 15 different setups. It is an affordable solution for shape checking applications. The CVS4 is the first true OCR sensor to enter the market. It provides detection and verification of date codes and lot codes (serial codes) using a sensor. It can read up to 60 characters on six lines, making it very flexible.
