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 sensorSix 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.
Thanks to redundant detection, 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.
Innovative safety technology
The new safePXV manages all that a single positioning system can with just one sensor. The new safety technology combines a 2-D reader with a three-coloured Data Matrix code tape. The special code tape contains two overlapping Data Matrix codes in red and blue.
The 2-D reader is equipped with two different coloured LED rings—also red and blue. These rings are activated separately and then read just one Data Matrix code each. An SIL 3/PL e absolute position is always provided as the result.
Pepperl+Fuchs is one of the world´s leading providers of industrial sensors and explosion protection. Based on an intense dialogue with our customers for more than 70 years we continue to develop new components and solutions, which support their applications the best way possible.
For the landmark topic Industrie 4.0 (Industrial Internet of Things) we develop innovative technologies that pave the way to the digital networked production and to data transfer across all hierarchy levels – even beyond companies´ boundaries.
Industrial sensors: focus on the market
Market-specific solutions dominate an extensive portfolio of industrial sensors that covers all applications the market requires from today´s automation technology. From the inductive and capacitive to the photoelectrical and highly precise ultrasonic sensors, identification systems and many more Pepperl+Fuchs offers all current operating principles in a broad variety.
Sensorik4.0® provides sensor technology for Industrie 4.0. Our technologies enable sensors without difficulty to communicate horizontally within the production process and to exchange data vertically – even into higher-level information systems such as MES or ERP.
Process interfaces: secure applications
Components and technologies for use in hazardous areas are designed to fit the most specific requirements in the industries we serve. They guarantee maximum availability at maximum safety. Isolated barriers, signal isolators, remote I/O or fieldbus systems, HMIs and many other technologies offer solutions for a wide range of applications including certified packaged solutions and all types of explosion protection.
Ex-Protection4.0 brings digital networked Industrie 4.0-production structures to process industries. With concept studies like Ethernet for Process Automation integrated communication throughout all levels of an automation system via Ethernet becomes feasible – for the first time ever even down to the filed level.
