The Retro-Reflex Sensor with Light Band scans a significantly larger range than a retro-reflex sensor with a dot-shaped light spot. This makes it ideally suitable for reliably detecting the front edges of objects with irregular shapes or variable sizes. The sensor´s collimated laser light is absolutely homogeneous and can thus be precisely aligned to the conveyorbelt´s level. The sensor detects objects from as little as just 4 millimeters over its entire range and light band height. The compact format can be integrated into the smallest of spaces, for example in the side panels of conveyor systems.
