At their most basic level, encoders transform mechanical rotary motion into a sequence of electrical pulses that are monitored for display or control functions using a counter, display, PC, PLC, ...

Rotary and linear optical encoders are common in position and motion sensing. ... For each encoder position, there is a different binary output -- shaft position is absolutely determined.

If you have a brushless motor, you have some magnets, a bunch of coils arranged in a circle, and theoretically, all the parts you need to build a rotary encoder. A lot of people have used brushless… ...

In devices which use rotary knobs, the AS5601 and its paired magnet may replace a rotary encoder without any change to the host microcontroller or its application software.
