A rotary transmitter for registration of the steering angle of a motor vehicle, with a transmitter component (49) on which is provided a coding (51) of a predetermined number n of locally sequentially digital words (W.sub.i) with a width of m bits (b.sub.1, b.sub.2, . . , B.sub.m) in m adjacent to each other tracks, at least one detector (55) for essentially simultaneous registration of the individual bits (b.sub.1, b.sub.2, . . . , B.sub.m) of a digital word (W.sub.i), whereby the transmitter component (49) and at least the one detector (55) are movable relative to each other, and with an evaluation unit (11) to which is conducted the signal of at least the one detector (55). The evaluation unit (11) ascertains the absolute position of the transmitter component (49) relative to at least the one detector (55), at least one time, by evaluation of a predetermined number (p) of sequentially detected digital words (W.sub.i), whereby the evaluation unit (11) assigns to a detected p-measure (W.sub.i, W.sub.i+1, . . . , W.sub.i+p-1), consisting of the predetermined number (p) of sequentially detected digital words (W.sub.i), a defined position value of the transmitter component (49) relative to at least the one detector (55). The coding is hereby designed in such manner that all sequences (W.sub.i, W.sub.1+1, . . . , W.sub.i+p-1) from among the sequential words (W.sub.i) consisting of the predetermined number (p) are uniquely defined at least within a predetermined uniquely defined area (I. II) of coding (51) and that within each uniquely defined area (I, II) the digital words (W.sub.i) are not uniquely defined.
