The 2-D read heads lie at the heart of the Data Matrix positioning systems. They consist of a camera module with an internal illumination unit. This enables them to detect the position information from the Data Matrix codes printed on the self-adhesive code tape.
With a large reading window, the read heads are capable of reading up to five Data Matrix codes at once in a single reading process. This means they provide reliable position detection even when codes are dirty or damaged. The PXV’s large reading window offers an even higher mounting tolerance for route guidance.
Due to their quick and comprehensive parameterization and adjustable inputs and outputs, the 2-D read heads can be adjusted to the specific application. Pepperl+Fuchs offers the read heads in different versions to meet a range of requirements. Whether PCV, PXV, or the safePXV, you can choose from different interfaces and sizes of reading window.
Safety Guaranteed
For safety applications up to SIL 3/PL e, users can choose either the safePXV safe stand-alone variant or the safePXV/PUS read head in combination with a safe evaluation unit (PUS). With a multicolor concept, the standalone variant already has multiple redundancy in itself. The multicolor Data Matrix codes on the robust code tape are made visible and read by the two-color illumination of the safePXV read head. The safePXV's algorithm already checks the plausibility of the data in the sensor. In combination with the safe evaluation unit, the evaluated data—in addition to the PROFIsafe safety protocol—is now also transmitted to the safe controller via EtherCAT®/Fail Safe over EtherCAT® (FSoE).
Several hundred products with a SIL/PL assessment, free tools, and brochures in one place: the "Functional Safety Hub" is your starting point when you have to implement safety functions.
For the first time, the new absolute positioning systems safePXV and safePGV realize safety level SIL 3/PL e with a single sensor …
