AS5132 Magnetic Rotary Encoder

ams' encoder enables accurate angular measurement over a full 360° turn

ams AS5132 Magnetic Rotary EncoderThe AS5132 contactless magnetic rotary encoder from ams enables accurate angular measurement over a full 360° turn. It is a system-on-chip, combining integrated Hall elements, an analog front end, and digital signal processing in a single device. To measure the angle, only a simple two-pole magnet, rotating over the center of the Hall element position, is required.

The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 8.5 bit, or 360 positions per revolution. This digital data is available as serial output over the interface and as a pulse width modulated (PWM) signal. An additional U V W output can be used for a block commutation for a brushless DC motor. To improve the torque over speed, a pre-commutation is possible. An incremental signal is available as an option.  AS5132 Datasheet
