Reading minuscule codes

For traceability management of increasingly smaller products like electronic components and batteries, reading microscopic DataMatrix codes directly marked on metal parts is a critical challenge. 2D codes printed with direct part marking (DPM) are often difficult for conventional code readers to read stably due to factors like reflections from metal surfaces, hairline finishes, and low contrast. This can lead to production line stoppages and become a bottleneck in quality control.

The KEYENCE AI-powered code reader, SR-X Series, was developed to solve these issues. With its overwhelmingly powerful reading algorithm and high-resolution sensor, it instantly and stably reads microscopic and challenging codes that were previously difficult to read. In particular, the AI function learns slight changes in printing conditions and continuously adjusts to the optimal settings automatically, ensuring stable operation over the long term. It delivers high performance even under adverse conditions such as on curved metal surfaces or cast surfaces. This technology eliminates minor stoppages caused by reading errors, supporting productivity improvements and the construction of high-precision traceability systems.
