摘要
A magnetic detector for detecting a rotational angle of a gear-like rotary member of magnet material generates twice as many pulses as the number of projected or recessed portions of the rotary member of magnetic material. The magnetic detector comprises a magnet for generating a magnetic field, a rotary member of magnetic material disposed with a predetermined gap retaining relative to the magnet, and an magnetic field sensing device for detecting changes in the magnetic field by movement of the moving member of magnetic material. The magnetic field sensing device is disposed relative to the magnet so that a center axis of the magnetic field sensing device is aligned with a center axis of the magnet wherein a magnetic field acting on the magnetic field sensing device changes from positive to negative and from negative to positive with the movement of the moving member of magnetic material.
