A multi-turn non-contacting rotary shaft position sensor that determines a positional parameter of a rotating shaft. The sensor converts the rotational movement of an input shaft to a linear translational movement of a magnetic element. A magnetically sensitive sensor is provided in a fixed location in close proximity to the magnetic element within the flux field of that magnetic element. As the input shaft rotates, the magnetic element moves along that linear path toward or away from the magnetically sensitive sensor so that the sensor detects the change in the magnetic flux imposed by the magnetic element. That change in magnetic flux is used to determining a positional parameter of the input shaft.

1. A rotary shaft position sensor comprising:a housing; a magnetic element producing a magnetic field and located within said housing, said magnetic element adapted to be translatable along a linear path within said housing but constrained from rotational movement; said magnetic element having a threaded shaft extending therefrom; a rotatable input shaft threadedly affixed to said threaded shaft, said rotatable input shaft adapted to be rotated to translate said magnetic element along said linear path within said housing, and a sensor positioned in proximity to said magnetic element and within said magnetic field, wherein said linear movement of said magnetic element causes a change in the magnetic influence of said magnetic field on said sensor.
