Scanning product type codes on outer boxes

In manufacturing lines for products such as pharmaceuticals, cosmetics, and food, accurately reading the product type codes on outer boxes to prevent incorrect loading and shipping due to product mix-ups is a critical process that forms the foundation of quality control and ensuring traceability. In particular, for workpieces on high-speed conveyors or when there is variation in print quality, stable reading has often been difficult with conventional code readers.

This image shows an application example of a fixed-mount code reader instantly reading a DataMatrix (2D code) printed on an outer box before assembly. KEYENCE's SR-L Series Code Reader for Moving Objects and Labels achieves both an ultra-wide field of view and long-distance reading performance through its proprietary optical technology. This allows it to instantly capture codes and maintain an extremely high reading rate, even when the position or height of the workpiece varies on the conveyor. It can easily track fast-moving objects, enabling reliable product type identification without slowing down the production line's takt time.

This automation solution significantly contributes to reducing human error, strengthening traceability systems, and improving productivity.
