Maximum Reliability Large Reading Window and Codes Enhance Performance of 2- D System

96

The PXV 2-D absolute positioning system from Pepperl+Fuchs sets new performance benchmarks when it comes to reliability and handling. With its large reading window, the system keeps a sufficient number of codes in view, even in relation to track switches and changes to the code tape. Precise positioning is guaranteed at all times.

The safePXV and safePGV sensor

Six years of experience with the PCV system have helped to shape the development of the PXV. The reading window of the PXV has been enlarged to approx. 120 x 80 mm, meaning that the Data Matrix code tape is always located within the sending range. Mounting and commissioning are easier, and plant availability is further improved. The reading window has an increased depth of focus range, allowing it to capture even more codes simultaneously and also guarantee position detection through multiple redundancy.

Unlike other systems available on the market, the PXV requires only a 2-D camera, ensuring that irritation relating to track switches is excluded. To prevent this, the cameras in the two-camera systems can receive the relevant differing position signals in these areas.

A certain degree of contamination on the code tape is often unavoidable during everyday operation. For this reason, the codes for the PXV have been expanded to 15 x 15 mm without compromising the resolution, and the coarse-grained design ensures that they are unaffected by contamination. The system also cannot be disrupted by the destruction of individual codes. The code tape can be interrupted by a stretch of up to 80 mm without affecting position detection.
