Abstract
Position sensors, including linear position sensors, that utilize magnetic field(s) are disclosed. Disclosed sensors include flux emitters and sensor assemblies. The sensor assemblies include flux collectors that interact with magnetic fields from flux emitters and with a magnetism sensing device. Flux emitters have arrangements of magnets that when combined with the sensor assembly can provide a constantly increasing or a constantly decreasing signal across a range of relative movement.
