In the fields of industrial and mobile automation, position sensors need to meet a large number of demands. Sought-after characteristics are robustness, speed, accuracy and – especially with regard to Industry 4.0 – communication capacity. At the same time, it is also the measuring task at hand that determines the choice of measuring principle and the suitable sensor. As is the case with many technologies, there aren‘t any allencompassing solutions in position sensing technology. This is where some guidance is important, especially in light of the cost factor, which is a considerable issue with many applications.
