AS5161 ROTARY POSITION SENSOR

12-Bit Rotary Position Sensor With PWM Output and Overvoltage Protection

The AS5161 is a contactless Hall-based magnetic position sensor for very accurate angular measurement over a full turn of 360°. It is a compact integrated solution which provides the absolute angle measurement with a resolution of 0.09° over a full revolution as PWM output signal. The internal 14-bit core of the AS5161 enables a fine programming of the start and stop positions with a resolution of 0.02° to allow the finest system mechanical adjustments.
