ABSTRACT:
A rotational angle sensor detects a rotational angle of a rotary member based on a magnet field produced across the rotary member by a pair of magnets. At least one magnetic detection device is disposed within a holder and serves to detect the magnetic field and to output a signal representing the rotational angle of the rotary member. For example, the holder may be mounted to a fixed place. A printed circuit board is coupled to the holder and is electrically connected to the at least one magnetic detection device. A positioning device serves to position the at least one magnetic detection device in a predetermine position relative to the holder.
