Contrast sensors determine contrast by sensing reflected white light to detect the difference in the wavelength of the reflected light between the mark and background. With detection ranges up to 40mm, these Wenglor sensors have IP67 rated plastic housings and quick-disconnect termination, offer teach-in sensitivity adjustment, and a choice of PNP or NPN output.
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.
