<p>A digital transducer, which can be engaged with a rotary or rotating shaft comprises a rotating sector (16) provided with apertures or perforations (16a) arranged according to arcs on different radiuses, having predetermined angular extension according to a binary code with a selected number of components corresponding to the number of bands of apertures on the different radiuses, information areas being defined for each aperture set positioned on different radiuses included in a predetermined angle. It advantageously provides, in an area adjacent to the information areas, a set of auxiliary apertures or slots (30) arranged according to arcs with the same angular extension, all aligned on the same angle, an aperture being provided at each information band.</p> |
