The robust RLS radial and axial magnetic rings consist of an elasto-ferrite layer which is bonded to a steel hub. The elasto-ferrite layer is magnetised with nonius magnetisation with different pole lengths and different numbers of magnetic periods.

If you’re looking for superior performance absolute rotary encoder, RLS also offers our own proprietary technology based AksIM encoder. For more information and comparison visit here.
