Patent ID: 7268538

Claim:
A magnetic rotational position sensor, comprising: first and second magnets spaced apart to define an air gap and cooperating with one another to generate a magnetic field extending across said air gap and positioned along an axis of rotation; a first magnetic flux sensor defining a first sensing plane extending along a first sensor axis, said first sensor axis arranged substantially parallel with and offset from said axis of rotation, said first magnetic flux sensor positioned within said magnetic field and operable to sense varying magnitudes of magnetic flux in response to relative rotational movement between said magnetic field and said first magnetic flux sensor about said axis of rotation and to generate a first output signal representative of a rotational position of said first magnetic flux sensor relative to said magnetic field; and a second magnetic flux sensor defining a second sensing plane extending along a second sensor axis, said second sensor axis arranged substantially parallel with and offset from said axis of rotation, said second magnetic flux sensor positioned within said magnetic field and operable to sense varying magnitudes of magnetic flux in response to relative rotational movement between said magnetic field and said second magnetic flux sensor about said axis of rotation and to generate a second output signal representative of a rotational position of said second magnetic flux sensor relative to said magnetic field.
