What are incremental rotary encoders?
A rotary encoder is an electro-mechanical component that shifts angular position code of a shaft to analog or digital code. Also called the incremental rotary encoder, this component is available in two types namely the absolute and incremental encoders.
Absolute encoders are angle transducers as they indicate the current position of the shaft. Incremental rotary encoders on the other hand provide information about the motion of the shaft itself in terms of sped, distance and position. Rotary encoders are versatile in their use throughout many different applications including industrial controls, robotics, special purpose photographic lenses, computer input devices, controlled stress rheometers and rotating radar platforms.

How does an incremental rotary encoder work?
Incremental rotary encoders are designed to keep its position information, which is immediately available upon the application of power, even if the power is taken away from the system. Therefore the system does not need to be re-set to a calibration point upon the return of electricity.
This is possible through code wheels and gears that measure the fractional rotation and the geared code wheels recording the amount of revolutions of the shaft. Containing many code rings, it is able to provide data of the encoder position after even one revolution.
