What is a rotary encoder and what are its advantages

Rotary encoders are divided into two types: incremental encoders, absolute encoders, the models are EC08, EC11, EC12, EC16; incremental encoders are more common; absolute encoders are more expensive, and absolute encoders have Range range, so it is generally used on machine tools with special needs.

Rotary encoders have the following advantages. Economical. Regarding multiple control stations, only the cost of one encoder is needed, and the more important equipment, protection, and loss cost are reduced, and the service life is increased, and its economicalization is gradually highlighted. Informationization, in addition to positioning, the control room can also know its specific location; multi-function, in addition to positioning, it can also remotely transmit the current position and convert the movement speed. It is particularly important for the use of inverters, stepping motors, etc.

Flexible, positioning can be adjusted flexibly in the control room. Convenience, safety and longevity of on-site installation: A rotary encoder with the size of a fist can measure intervals from a few μ to several hundreds of meters, n stations, and only need to process one rotary encoder (Changchun encoder) The safety device question can prevent many close switches and photoelectric switches from troublesome mechanical installations on the spot, and they are simply damaged by high temperature and water vapor. Because of the photoelectric code wheel, there is no mechanical loss, only the device position is accurate, and its service life is often very long
