8-bit rotary position sensor with digital interface and PWM output The AS5130 is a contactless magnetic rotary position sensor (previously known as encoder) for accurate angular measurement over a full turn of 360°and over an extended ambient temperature of -40°C to +125°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8 bit = 256 positions per revolution via a serial bit stream and as a PWM signal.
