Contrast Print Mark Sensors

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 18mm, with quick-disconnect termination.

Contrast Sensors

Contrast sensors are photoelectric sensors that determine contrast by sensing reflected white or RGB light (red, green, 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.
