Courtesy: AutomationDirectThe Datalogic S8 series print mark contrast sensors have 6 to 12mm sensing distances and are designed to detect the difference in the wavelength of the reflected light between a target mark and background. The contrast sensors use RGB light emission with automatic selection, and feature teach-in sensitivity adjustment, and selectable light on/dark on outputs. The S8 series compact contrast sensors feature horizontal spot orientation, a 25 kHz switching frequency, NPN or PNP logic output, 12 to 30 Vdc operating voltage, and are available with IP67-rated plastic or IP69K-rated 316L stainless steel housings. The S8-series sensors are fitted with a 4-pin M8 quick-disconnect or have an attached 150mm cable with M12 quick-disconnect. The contrast sensors feature vertical or horizontal spot orientation, 10 to 30 Vdc operating voltages, aluminum housings, and NPN/PNP or PNP logic outputs.
