Cognex DataMan 280 barcode reader with dome lighting

Cognex Corporation has released the DataMan 282 fixed-mount barcode reader, outfitted with the company’s high-powered integrated torch (HPIT) and optional dome lighting attachment. These lighting components enhance the reader’s ability to read direct-part marks (DPMs) by optimising lighting contrast and minimising glare and background interference.

DPMs are notoriously difficult to read as they are often imprinted on curved, shiny metal surfaces, such as electric vehicle (EV) components, consumer electronics and medical devices. These challenging surfaces cause some barcode readers to pick up too much glare, failing to illuminate the component or isolate the code.

The dome diffuser is designed to help deliver high read rates on direct-part marks by illuminating components while minimising background noise, even on reflective surfaces.

In addition, the HPIT enables users to change between red, white, blue and green lighting options with a single click. Multicolour lighting allows users to pair the right lighting colour with their application, helping to increase image contrast and leading to higher read rates and throughput.
