The AS5130 utilizes a spinning magnet above the sensor IC. The sensor measures the angle of the magnetic field and outputs the angle via an incremental encoder interface. It is designed to be robust and reliable even when exposed to stray magnetic fields. The sensor is end of life, and while existing systems continue to use it, it isn't being designed into new ones.
