What are the advantages of rotary encoder?

Rotary encoder is widely used by the market, so, in contrast, the rotary encoder what advantage? As we know, is a kind of photoelectric rotary encoder rotation measurement device, it will be converted into digital signals directly measuring of angular displacement. Its advantage is embodied in the following four aspects: (1) according to the quantity of the rotation of the shaft displacement output through joint combined with shaft and can detect rotating displacement directly. (2) without the origin reset when it is started. ( Only absolute type) Under the condition of absolute type, rotation Angle as equal output of absolute value. (3) to test the direction of rotation. Incremental type through the output of the A and B phase in time, the absolute type is allowed to grasp the direction of rotation through the code. (4) please according to the resolution of the rich and the output type, select the most appropriate sensors. According to the required precision and cost, connection circuit, etc. , choose suitable sensors. Through introducing the advantage as rotary encoder, I believe you must know why rotary encoder are so popular among the! ! ! !
