Abstract
A sensor assembly includes a substrate including a first portion, a second portion, and a rolled section positioned between the first portion and the second portion. The sensor assembly further includes a first magnetic field sensor coupled to the first portion. The first magnetic field sensor has a primary sensing direction aligned with a longitudinal axis of the sensor assembly. The sensor assembly further includes a second magnetic field sensor coupled to the second portion. The rolled section is shaped such that the second magnetic field sensor is oriented with respect to the first magnetic field sensor so that the second magnetic field sensor has a primary sensing direction aligned with an axis orthogonal to the longitudinal axis.
