Cognex Corporation ( has introduced new lighting and optics features for its DataMan® 300 series of industrial barcode readers. Since its launch, DataMan 300 has quickly become the preferred barcode reader due to its outstanding read rate performance and ease of use. The demand is now set to continue with the introduction of the most flexible optics and lighting features available on any image-based fixed-mount barcode reader.

Easier to use for multiple applications

“Instead of having to order and stock different models, our customers can now easily configure DataMan 300 for multiple applications by simply changing the lighting or optics,” says Carl Gerst, vice president and business unit manager, ID Products. “As an added benefit, having the ability to optimize lights and optics for each application helps achieve the highest read rates possible.”

Greater customization and control

The DataMan 300 features modular lighting that can be configured and replaced in the field. The eight integrated light banks and external lights can be individually controlled.

Lighting options include:

  • IR for challenging metal parts and operator eye comfort
  • Polarized red for reflective parts or parts under plastic
  • Blue for metal parts or barcodes printed in color
  • High-intensity red for general purpose applications
  • Cognex’s custom high-powered illumination accessory (HPIA) for long-range barcode reading applications
  • Several external lights powered directly from the reader, including the ring, backlight, spotlight, low angle ring and DOAL

Reduced need for additional hardware

The DataMan 300 lens mount supports all popular lens styles without any additional hardware.

Lens options include:

  • Variable focus S-Mount liquid lens
  • S-Mount in 10, 16 and 25 mm
  • C-Mount in industry standard sizes

Automatically adjusts to optimal settings

With the press of a button, the DataMan 300 “intelligent tuning” feature runs an automatic calibration routine that determines which combination of lights and focal distance on the liquid lens will provide the best results for each application.

The DataMan 300 series includes three models: DataMan 300, with a standard resolution of 800x600 pixels, the DataMan 302, with a higher resolution of 1280x1024 pixels, and the DataMan 303 with the highest resolution of 1600 x 1200 pixels.
