AS5134 Rotary Position Sensor

8.5-bit Rotary Position Sensor With Digital Angle (interface), ABI, UVW and PWM Output

The AS5134 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 +150°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.
