Canceling magnetic pickup using three-dimensional wiring assembly

A wiring assembly (111) includes a differential input port (60a,60b), a differential output port (62a,62b), and first (54a,54b) and second (55a,55b) pairs of electrical conductors. The differential input port (60a,60b) is configured to receive a differential signal from a sensor at a first end of the wiring assembly (111). The differential output port (62a,62b) is configured to output the differential signal at a second end of the wiring assembly (111). The first and second pairs of electrical conductors are laid out in a three-dimensional (3D) crossover configuration relative to one another and configured to conduct the differential signal from the first end to the second end, and to cancel pickup of a magnetic field by the wiring assembly (111). The electrical conductors of each pair are connected to one another at the first end and at the second end.
