along an axis generally parallel to the sensing plane 62 as shown in fig4 the angular position sensor 20 is in a quiescent state in this state the magnetic flux density b represented by the arrows identified with the reference numeral 68 is generally parallel to the sensing plane 62 of the magnetic sensing device 43 in this state the magnetic sensing element 43 outputs a quiescent voltage for an allegro model no 3506 hall effect ic the quiescent output voltage is typically about 2 5 volts dc rotating the magnet 42 counterclockwise as shown in fig5 or 6 or clockwise not shown causes an ever increasing amount of magnetic flux density 68 to be applied to the sensing plane 62 of the magnetic sensing element 43 to vary the output voltage of the magnetic sensing element 43 as a function of an angle u03b8 defined between an axis 63 parallel to the sensing plane 62 and an axis 65 for an allegro model no 3506 the output voltage swing is approximately u00b1 2 0 volt dc depending on the direction of the angular rotation in accordance with an important aspect of the invention the relationship between the axes 63 and 65 can be varied in order to adjust the offset voltage of the sensor 20 in particular the assembly 60 is rotated relative to the magnet 42 in a quiescent state to adjust the sensor offset voltage in such an application the sensor would be configured in the quiescent state to have a small angle u03b8 between the axes 63 and 65 as illustrated in fig4 as will be discussed.
