    Intended Use The Data Matrix Positioning System is the positioning system in the Pepperl+Fuchs incident light process. The heart of the system is the read head, which consists of a camera module with an internal illumination unit. This enables the read head to detect position markers printed onto a self-adhesive code tape in the form of 2-D Data Matrix codes.

  • Page 8: Useful Lifetime

    PXV80AQS-F200-R4-V19 Safety Information Useful Lifetime The useful lifetime is specified in the characteristic safety values. . Although, on the basis of a probabilistic estimate, a constant failure rate is assumed, this only applies under the condition that the useful lifetime of the components is not exceeded. The result of this probabilistic estimate is only applicable until the useful lifetime ends, as the proba- bility of a failure significantly increases thereafter.

  • Page 28: Expansion Joints/Gaps

    PXV80AQS-F200-R4-V19 Planning Expansion Joints/Gaps To compensate for temperature-related changes in length in plant structures, expansion joints are usually required for longer tracks. If a Data Matrix code tape is applied at such locations, we recommend that you interrupt the code tape at the edge of the expansion joint and continue with a fully readable Data Matrix code tape.
  • Page 29 PXV80AQS-F200-R4-V19 Planning Examples of the Gap Width for Consecutive Missing Data Matrix Codes The read head expects Data Matrix codes with an ascending number sequence in a predefined pattern. There is a new code every 20 mm. This pattern should be adhered to as far as possible at the interruptions to avoid position jumps.
  • Page 30 PXV80AQS-F200-R4-V19 Planning Cutting Rule The code tape is laid from right to left in ascending order of position, whereby the distances between the codes are defined by the pattern of the code tape. 000 000.0 m PXV-AA25 www.pepperl-fuchs.com 2 mm 2 mm Figure 5.14...
  • Page 31 PXV80AQS-F200-R4-V19 Planning Case 2 - Continuation Glue the Data Matrix code tape up to the gap and cut out the codes in the area of the gap. Con- tinue the code tape at the next component. Advantage: In the case of extremely wide gaps, the Data Matrix code tape can be optimally mounted along the mechanical gap.
  • Page 32 PXV80AQS-F200-R4-V19 Planning The x value remains constant at its historical value and shows a hysteresis of 21 mm. When the center of the image approaches the next code, there is a jump.
