1D/2D code readers - System description

  • Reading of Data Matrix codes in accordance with ECC200.
  • Very small housing for flexible use.
  • Simple, menu-guided parameter setting.
  • Integrated lighting.
  • High reading reliability even with soiled / damaged codes.

Data Matrix code readers
Throughout industry one code is becoming more and more popular: the Data Matrix code to ECC200. In this code lots of information can be stored in a very small space and read using a suitable Data Matrix code reader. With a size of only 42 x 42 x 44 mm the extremely compact 2D sensor efector dualis takes us to a new dimension. It is now possible to solve applications where mounting space is at a premium. Furthermore, the industrially compatible mounting and wiring technology enables easy and quick process connection.

The Data Matrix code
The Data Matrix code is two-dimensional containing much more information with the same structure size than comparable codes like bar code or stacked codes. Several thousand characters can be stored in a code. Further advantages are the high reading speed and excellent data protection. The Data Matrix code can be structured differently and is variable in shape and size. The size can cover 1 x 1 mm to 100 x 100 mm, the shape can be square, rectangular or designed as a multi-segment code. Characteristic features are a rectangular "finderbar" for the orientation of the code as well as the "alternating grid" for structuring. The data zone is within these "help elements". Around the code a "quiet zone" is necessary where no interfering structures are allowed and which must at least cover one module width (one square is called a "module").

High reading security
An important feature of the Data Matrix code is the high reading security even if the code is soiled or damaged. The reason for this is multiple presence of one and the same information at different positions in the data zone. If the code is damaged, the intelligent system can completely recompose the information from different segments again. For the efector dualis the Read Solomon principle is applied which can decode the code even if 28% of the information is destroyed.
