Readable, compliant, traceable

Omron's new VHV5 Inline Verifier high-speed barcode verification technology enables manufacturers to verify 1D, 2D, and Direct Part Mark (DPM) codes directly on the production line. The VHV5 performs real-time verification of Code 128, Data Matrix, QR codes, and DPM markings at speeds of up to 1,000 codes per minute. This allows companies to ensure that every code applied during marking or printing is readable, compliant, and traceable.

In manufacturing and packaging environments, barcode quality directly impacts aspects such as traceability, compliance, and reliable scanning during internal handling, final assembly, distribution, and at the point of use. Inline verification allows manufacturers to assess code quality immediately after creation, enabling them to identify and resolve printing or marking issues instantly.

The VHV5 complies with ISO/IEC 15416 for the print quality of 1D barcodes, ISO/IEC 15415 for the evaluation of 2D symbols, and ISO/IEC TR 29158 (AIM DPM) for codes applied directly to parts using laser, dot peen, or inkjet processes. By adhering to these standards, the system delivers consistent and repeatable evaluation results for labels, packaging, and permanently marked components used in the automotive, medical, electrical, pharmaceutical, and general manufacturing industries.

This device utilizes tilted coaxial lighting, which ensures improved verification accuracy on reflective, curved, and low-contrast surfaces. This is achieved through minimized glare and optimized edge sharpness. This optical approach is particularly effective for DPM codes on metal parts, glossy labels, and curved plastic packaging, commonly found in high-speed production lines.

To ensure accurate evaluation in installations with limited space and challenging viewing angles, the VHV5 utilizes unwarp transformation technology. This corrects image distortion caused by curved or angled surfaces, enabling precise axial non-uniformity classification of 2D codes. Flat-field correction also ensures uniform illumination and pixel response across the entire field of view, preventing lighting artifacts from affecting evaluation results regardless of code position.

The system also features integrated GS1 syntax checking for validating the coded data structure and ISO evaluation. This allows manufacturers to identify formatting errors before products leave the factory. Setup and operation are simplified by a guided calibration wizard and a browser-based WebLink interface, enabling configuration, monitoring, and diagnostics without additional software.

The VHV5 builds upon Omron's decades-long leadership in barcode verification. The company is known for technologies that enjoy widespread trust worldwide, particularly in regulated industries.
