1. A pick-up for the angular position of a shaft (1) rotating in a stationary body (2) and comprising : a reader (10, 11, 12, 13, 14) equipped with a number of detecting elements, and also comprising a device for adjusting the position of the reader and comprising an adjusting plate (15) on which the reader is secured, and a disc (4) bearing a coded surface (4a) and co-rotatably secured to the rotating shaft, the pick-up being characterised in that it comprises means for radially moving the adjusting plate (15) relative to the stationary body (2) of the pick-up and comprising centring screws (18) acting in opposing manner in a plane substantially perpendicular to the axis (XX) of rotation of the rotating shaft (1) and the disc (4), the pick-up also comprising a washer (16) having the same geometrical shape as the adjusting plate (15), the washer being radially secured with respect to the stationary body (2) and with one of its surfaces in contact with that surface of the adjusting plate (15) to which the reader (10, 11, 12, 13, 14) is not secured, in order to facilitate radial movement of the adjusting plate during adjustment thereof. |
