The sensor assembly consists of an over-molded package that holds together a samarium cobalt magnet, a pole piece concentrator, and a true zero-speed Hall IC that has been optimized to the magnetic circuit. This small package can be easily assembled and used in conjunction with gears of various shapes and sizes. The sensor incorporates a dual-element Hall IC that switches in response to differential magnetic signals created by a ferrous target. Digital processing of the analog signal provides zerospeed performance independent of air gap as well as dynamic adaptation of device performance to the typical operating conditions found in automotive applications (reduced vibration sensitivity). High-resolution peak detecting DACs are used to set the adaptive switching thresholds of the de...
