Scanning product serial labels

Reading product serial labels on a production line is an essential process for establishing traceability and a quality control system. Particularly for electronic circuit boards (PCBs) and small components transported at high speed on a conveyor, stable reading accuracy is the key to improving productivity. However, variations in label print quality and light reflection (glare) from outer films were major causes of reading errors with conventional barcode readers.

The KEYENCE SR-L Series code reader for moving objects and labels solves these on-site challenges. Its class-leading compact design makes it easy to retrofit to existing equipment or install in limited spaces. The main unit has powerful built-in lighting and a polarizing filter, which suppresses glare even when reading glossy label surfaces or through protective films, achieving clear imaging. The latest AI-powered reading algorithm instantly decodes challenging codes with faded or dirty print, enabling stable operation.

This innovative technology can dramatically improve the accuracy of individual item and process management in various FA (factory automation) sites, such as for electronic and automotive components.
