Abstract: Different approaches for providing increased redundancy in determining a position of a rotating member, for example, a motor shaft, with galvanically isolated sensors. In one aspect, two separate on-axis sensing chips are positioned in line with one another on a PCB but each on opposite sides or surfaces of the PCB. Respective sensing surfaces are essentially parallel to one another. Advantageously, greater electrical isolation is provided by placing the two sensors on opposite sides of the PCB.
