SIMPSpad position sensing
SIMPSpad is a position sensor technology that is characterized above all by its ability to measure non-ferrous metals. Based on an inductive principle, it can detect simple metallic or resonant targets. To enable this technology to measure non-ferrous metals as well, a layer of highly permeable soft magnetic material is added and operated with a magnetic target.
