Magnetic sensing requires no bearings between sensor head and material measure (here a center magnet). This way they can be positioned separated from each other. This allows for rather high mounting tolerances and increased flexibility in design and mounting. As there is no need for bearings, there is no conventional wear and tear either. This way the encoders are immune to dust, dirt, textile fibers, shaft currents or bearing loads and robust against vibration and shock.
