Rotary encoder - Wikipedia

A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the An incremental encoder works differently by providing an A and a B pulse output that provide no usable count information in These encoders use the principle of energy harvesting to generate energy from the moving shaft.
