Color & Contrast Sensor
Using color marks that are then analyzed with a color or contrast sensor is a reliable technique for identifying objects in industrial settings. This method can accurately detect objects of various shapes and surface properties with ease.
Sort packaging, check labels, detect color, and color ranges with Color Sensors. Detect and check printing marks for the subtlest variation with contrast sensors. Employ luminescence sensors to easily detect labels on difficult surfaces such as glass bottles.
How does Color Sensors work?
Color sensors work by analyzing the red, green, and blue spectra separately to determine the color of an object. They can emit light in these colors one by one and measure the reflection (FT 25-C), or use white light split into RGB in the receiver (FT 50 C). The sensor then compares the color values with known references and triggers an output if they fall within the set range.
Classic Color Detection Applications
SensoPart introduces the FT 25/50 C color sensors, perfect for accurately detecting colors of objects and printed marks. The FT 25-RGB is great for quickly identifying a single color, while the FT 50 C can distinguish between various colors and custom color ranges. With its exceptional color selectivity, this sensor is ideal for a wide range of industrial color detection tasks.

Detection with Contrast Sensors
The F 25 series features advanced contrast sensors that can easily detect even the subtlest differences in contrast on objects or printed marks, all while operating at high speeds. The FT 25-RGB model, equipped with multi-color RGB evaluation, can intelligently choose the best transmission color (red, green, or blue) based on the detected contrast.
Best uses of Luminescence Sensors
The detection process works by using special materials called luminophores. These materials light up when exposed to UV light at a wavelength of 375 nm, which is invisible to the naked eye. The sensor then analyzes the unique light frequencies emitted by the luminophores and compares them to a reference value.
There are so many great uses for luminescent materials, like spotting labels on glass bottles, aligning objects with invisible marks, and finding oils with added fluorescent elements. You can also find luminescent materials in things like fluorescent chalks, paints, dyes, text markers, glues, sealants, lubricants, and optical brighteners used in paper, textiles, and plastics!
