ABSTRACT:
A sensor including at least one rotary magnetic coder with first and second rotary tracks, at least two detection cells, and logical resources for processing of digital signals delivered by the cells. At least the detection cell located in relation to a magnetic track with a singular pole is a single-element detection cell, and the generator elements of the magnetic tracks and the detection cells are arranged in dependence on the logical processing resources such that the digital output signal has the same constant period, both on its regular coding part and on its irregular coding part, and the regular coding part and the irregular coding part have cyclic ratios that are unbalanced and different from each other.
