Leading edge detection on the conveying equipment

Leading edge detection is used to optimize object distances during zero pressure accumulation. The signals from the sensors enable precise speed monitoring of the individual belt segments. The different objects must be reliably detected in the process. SICK offers the right solution for both belt and roller conveyors.
