Where Does a Rotary Encoder Applied！

Encoders are an ideal solution where there is a requirement for computer control and automated production. It is used extensively in robotics, machine tool, batching systems, and in fact any application where precise angular monitoring is required. They are also used for speed sensing, and control of rotating machinery. There are basically two types used in industry to-day:
(a) Incremental
(b) Absolute
With incremental encoders, when the electric power is removed, the encoders positional data is lost; whereas with absolute encoders the data is retained, this is very useful in indexing applications such as machine tool operation.
