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 Features
- 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.

Horizon to horizon 180 deg lighting eliminates
shadows and unwanted reflections
