Contrast Sensors+Color Sensors
Contrast sensors
Contrast sensors detect registration marks in printing, converting, packaging, food and beverage, and pharmaceutical applications for sorting, positioning, and quality control applications.
Outstanding features of our contrast sensors include their ability to distinguish high-resolution contrasts, fast response times, insensitivity to height and angle deviations to the sensed material, and interchangeable optics. The selection of the optimal color transmitter and the adjustment of the trigger level take place automatically with the simple push of a button.
For special applications in harsh environments, the DKE versions with stainless steel housings and the RL5-LL version with fiber optic cables are recommended.
Color sensors
As color is an obvious product characteristic, the recognition and reliable detection of colors play an increasingly important role in industrial automation. Equipped with outstanding features, the color sensors of Pepperl+Fuchs cover most applications, whether sensing color marks at a fixed distance or detecting colored objects at variable distances, and whether detecting an individual color or sensing ten colors. Fiber optic cables also allow color sensors to be used in harsh environments. Operation of the sensors is very easy: “Teach-in” of the color occurs with the push of a button.
Color tolerances can be taught by “re-teaching”. Programmed colors’ values are stored in the sensor’s memory, even after power-off. The short response time of our color sensors permits reliable color recognition in fast processes.
