Claim 18:
19. A magnetic sensing system comprising:
a magnetic sensing circuit responsive to a magnetic field generated by a magnetic element, the magnetic element comprising alternating positive and negative sections configured to generate the magnetic field in a first direction, and the magnetic sensing circuit responsive to the magnetic field in a second direction that is angularly offset from the first direction;
at least one magnetic flux pipe structure configured to conduct the magnetic field generated by the magnetic element and redirect the magnetic field generated by the magnetic element towards the magnetic sensing circuit in the second direction, wherein the at least one magnetic flux pipe structure comprises a mounting portion, a magnetic element coupling portion, and a sensor coupling portion, and wherein the magnetic element coupling portion and the sensor coupling portion are located at opposite ends of the at least one magnetic flux pipe structure, and wherein the mounting portion is attached to a printed circuit board of a control device, and wherein the magnetic element coupling portion is positioned adjacent to the magnetic element and located in a notch in the printed circuit board.
