What is an rotary encoder?！

A rotary encoder, also referred to as a shaft encoder, is a sensor that generates an electrical signal in response to a rotational movement. This signal is used to determine or control the speed or position of a mechanical device. A rotary encoder is mounted on a cylindrical shaft and is often used in combination with mechanical conversion devices, such as linear slides and rack and pinions, to measure linear movement. Rotary encoders are used on a wide variety of precision equipment that requires close control of position or speed, including medical devices, robotics, assembly machines, and testing equipment, among others.

There are two main types of rotary encoder. An incremental encoder generates a series of pulses, or counts, as it rotates. Its output is measured in pulses per revolution, and these pulses are used to measure speed or keep track of position. An absolute encoder generates an output signal that is in digital bits, with each bit corresponding to a known position. As a result, an absolute encoder can be used directly to indicate actual position.
