Incremental Rotating Magnetic Encoder and Photoelectric Encoder！

1, Advantages: small size, precision, resolution itself can be very high, no contact without wear; the same species can detect angular displacement, but also in the mechanical conversion device to help detect linear displacement; multi-cycle photoelectric absolute encoder can detect considerable Long-range linear displacement (such as 25-bit multi-turn). Installation at random, the interface forms rich, the price is reasonable. Mature technology, many years ago has been widely used at home and abroad.
2, Disadvantages: precision but the use of outdoor and harsh environments put forward higher protection requirements; measuring linear displacement to be dependent on mechanical device conversion, the need to eliminate the error caused by the mechanical gap; detection track object is difficult to overcome slip.

Incremental rotary magnetic encoder:
Is developed in recent years, a new type of speed, position detection digital sensor. Magnetic encoder on the surface of ferromagnetic materials recorded at regular intervals of magnetization scale, ruler next to the relative placement of magnetoresistance effect element or Hall element, can detect changes in flux, and then processed by the signal conversion card into a standard electrical signal Output.
Advantages
※ high speed, fast response
※ dust, oil
※ anti-vibration level is high
※ easy debugging, easy to install
※ line-driven output type, anti-interference ability
