Data Matrix Readers & Verifiers

Witness™ Reader PDF Print E-mail

Witness™ has the unique advantage of a 5 Mega Pixel imager which enables even the tiniest marks to be reliably read without the need to change optics or field of view.


Key Featureswitness

  • Witness™ reads direct and printed codes to international standards: 
  • ISO 16022 Data Matrix
  • GS1
  • HIBCC and EHIBCC
  • JES 131
  • MIL 130 UID
  • Powerful algorithms cope with low contrast, damaged and distorted marks with ease.
  • The Witness™ has a uniquely robust housing of machined stainless steel, sealed to IP67 standard, for ease of wash down disinfection or coolant proof operations
  • Real Time video display of the mark plus ‘hands free’ and ‘button free’ operation helps the Operator greatly increase throughput.
  • USB 2.0 PC interface without the need for a separate power supply for an uncluttered work space and true portability when used with laptops.
  • Software controlled lighting provides virtually 180 deg continuous illumination for shadow and reflection free reading from highly reflective surfaces.

These unique Witness™ advantages have led to applications as diverse as controlling the assembly of Automotive turbo charger components and identifying minute electronic components for Hearing Implants.
