Shaft Encoder

The rotary Encoder is a type of optical sensor that encodes the rotational motion or rotational position of a shaft or shaft as digital output. Precision and automation engineers use this equipment, which is actually an angle transducer, in many applications that require accurate shaft rotation measurements, such as robotics, CNC machines, motor speed
control feedback, etc. In general, two-encoders Types or categories are divided into:
absolute,
incremental, or incremental
The discussion of the mechanism for measuring the shafts of absolute and incremental encoders goes on. Getting the number of revolutions per unit time, for example in engines, if we want to use an increment, we must use it.
