Contrast print mark sensors determine contrast by sensing reflected light (either white or RGB) to detect the difference in the wavelength of the reflected light between the mark and background. Contrast sensors offer detection ranges up to 40mm, with quick-disconnect termination.
Contrast sensors are photoelectric sensors that determine contrast by sensing reflected colored light (red, green or blue) to detect the difference in the wavelength of the reflected light between mark and background.
Industrial applications include packaging lines, beverage and bottling lines, paper and printing machinery, and ceramics printing. S8 series sensors with stainless steel housing provide IP69K washdown protection for use in the food, beverage and pharmaceutical industries.
The S8 Series of Datalogic print mark contrast sensors discriminates fine contrast differences with RGB emission and offers high speed detection up to 25 kHz. IP69K versions are available.
The Datalogic TL46 Series is available in 3 versions: TL46-W with 2 teach buttons and 2 LED indicators; TL46-WL with 3 pushbuttons and LED bargraph; and the TL46-WJ low jitter unit (7 µs) with 50kHz switching frequency.
