The gear-tooth sensors are smart sensors that learn about their targets to optimize the magnetic circuit detection. Each module combines in a compact high-temperature plastic package: a samarium-cobalt magnet, a pole piece, and a differential Hall-effect IC that has learning capability. These sensors can be easily used in conjunction with a wide variety of gear or target shapes and sizes.
