Safety applications according to "SIL 3 / PL e" require adherence to the highest safety guidelines in order to optimally protect people and machines at all times. While this level of security was previously associated with high costs and time, users can do so with the "safePXV" and "safePGV" positioning systems from Pepperl + Fuchs. Based on a multi-redundant technology, the manufacturer claims that this enables absolute positioning to SIL 3/PL e with a single sensor for the first time. The safePXV offers the perfect solution for linear absolute positioning; the safePGV also for the reliable navigation of driverless transport systems. The basis of the new security technology is the proven and particularly reliable combination of a 2-D read head and the DataMatrix code. However, a special tape with two overlapping DataMatrix codes in red and blue is used here. The 2-D read head is equipped with two differently colored LED rings - also in red and blue. The two-color codes combined with the two-color illumination create the unique security solution. Each individual code contains position and safety information that is made visible in red or blue by the LED illumination and can thus be read out by the camera. Therefore, the safe X position can be processed there directly, without testing and used for process control.
