Scan Engine - 2D AI3255UL

AI3255UL Long-Range Compact 2D Barcode Scan Engine

The AI3255UL is a compact 2D barcode scan engine optimized for mid-to-long range scanning performance, making it ideal for both fixed and mobile OEM integrations. With an ultra-slim form factor of 11.1 × 21.7 × 7 mm, it is well suited for space-constrained designs while delivering extended reading distance and stable decoding.

Built around a 1280 × 800 CMOS image sensor and a cross-type laser aiming system, the AI3255UL provides fast and accurate barcode capture from printed labels and on-screen barcodes. It reliably reads barcodes displayed on paper, labels, smartphones, and LCD screens, supporting modern automation and mobile workflows that combine physical and digital identification.

With high-resolution decoding capability down to 4 mil for 1D (Code 39) and 5 mil for 2D (PDF417), the AI3255UL ensures consistent readability of dense barcodes. Its extended depth of field—up to 680 mm on 13 mil EAN-13— makes it particularly suitable for fixed-mount automation systems and production lines, where stable long-range scanning is required.

When integrated into fixed scanners, the AI3255UL is well suited for industrial automation, manufacturing lines, and automated inspection equipment. When embedded into handheld, pocket-sized, or ring-type devices, it supports warehouse operations, logistics workflows, and retail applications that demand fast scanning, flexibility, and user mobility.

Manufactured in Taiwan, the AI3255UL reflects our commitment as a trusted scan engine supplier to deliver stable, customization-ready solutions for OEM customers. Its long-range performance, compact design, and versatile application fit make it a strong choice for industrial and commercial identification systems.
