Color Sensor PR0047

The color sensor PR0047 is a system for the passive detection of color in the visible spectrum of light. Here the product to be detected is illuminated and the reflected light is evaluated.

The module can be used as a mere analog sensor but can also be used a Good/Bad detector via the digital interface.

Both interfaces can be used in parallel. In an application as Good/Bad detector the module uses product specific parameters configured by the user via the software tool contained in the scope of delivery. These parameters are permanently stored on the module. 16 different products can be parameterized and selectively tested.

The sensor captures all 3 color channels in parallel. The parallel capturing of all color channels as well as the specific measurement procedure lead to a high suppression of environmental effects.

The coupling of light is carried out via light guides. Here not only point-shaped areas but also larger areas can be controlled for matching of color. The module evaluates the area as sum signal.
