Abstract: A sensor assembly includes a first magnetic field sensor that is a first type of sensor and has a first magnetic field sensitivity in a first primary sensing direction. The first primary sensing direction is along a longitudinal axis of the sensor assembly. The sensor assembly further includes a second magnetic field sensor that is a second type of sensor different than the first type of sensor and has a second magnetic field sensitivity in a second primary sensing direction that is less than the first magnetic field sensitivity. The second primary sensing direction is along a second axis that is different than the longitudinal axis.

Abstract: A sensor assembly includes a multilayer circuit, a first magnetic field sensor, and a second magnetic field sensor. The multilayer circuit extends between a proximal end and a distal end along a longitudinal axis. The multilayer circuit includes a plurality of electrical pads positioned at the proximal end. The first magnetic field sensor is coupled to the multilayer circuit and has a primary sensing direction aligned with the longitudinal axis. The second magnetic field sensor is coupled to the multilayer circuit and oriented with respect to the first magnetic field sensor such that the second magnetic field sensor has a primary sensing direction aligned with an axis orthogonal to the longitudinal axis.

Abstract: A sensor assembly includes a first magnetic field sensor and a second magnetic field sensor. The first magnetic field sensor includes a first substrate and a first elongated magnetic field sensor component extending a first length. The second magnetic field sensor includes a second substrate and a second elongated magnetic field sensor component extending a second length that is shorter than the first length. The first magnetic field sensor has a greater sensitivity to a sensed magnetic field than the second magnetic field sensor.
