Features
Impressive Imaging Capabilities with an Integrated Design
With a conventional camera lens, the corners of the captured image are distorted and essentially unusable for reading. KEYENCE's newly developed imaging lens effectively utilizes the entire area captured by the CMOS image sensor, ensuring readability even in the corners of the image.

Ultra-compact imaging lens
New HDR wide-angle CMOS
Built-in 3-way illumination (direct, polarized, diffuse)

Integrated lens, illumination, and high-resolution CMOS
The integrated design allows for automatic configuration of the best settings without the need to select equipment or adjust settings. It automatically selects the optimal lighting conditions for the target.

Reliable Code Identification
SR-X Drive: KEYENCE's new decoding algorithm
AI filter for difficult code reading. Optimized specifically for code reading, the built-in AI inference chip is built by learning from a database of over 100,000 images. This results in dramatically improved code reading performance.

Link devices to improve reading and analysis
Stable reading is possible regardless of changes in code quality, and visualization of changes between runs is now possible. The SR-X Series allows for linking code readers within the same network, enabling time-series analysis of code condition changes for each installation environment. Linking information read from a code reader in a previous run with a code reader in a subsequent run enables reading even for codes with glare, smudges, scratches, or other damage.
