Abstract

The invention relates to a system having a coder with a magnetic track that exhibits an alternation of North and South magnetic poles separated by i Archimedean spiral transitions. The invention also includes a rotation sensor able to detect the periodic magnetic field emitted by the coder using several sensitive elements, the sensitive elements being distributed angularly along the magnetic track while forming between at least two sensitive elements an angle α which is designed so that the signals delivered by the elements are in quadrature.
