8.5-bit rotary position sensor with digital angle (interface), ABI, UVW and PWM output The AS5134D is a contactless magnetic rotary position sensor for accurate angular measurement over a full turn of 360 degrees and over an extended ambient temperature of -40°C to +140°C. The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit = 360 positions per revolution via a serial output over the interface and as a pulse width modulated (PWM) signal.
