Selecting the right encoder for any application

Selecting the right encoder
Initially, the encoders consisted of potentiometers, brush encoders and
magnetic encoders with optical encoders and resolvers being rare. Each device
had certain limitations. For instance, the potentiometers and magnetic encoders
had limited resolution while the brush encoders required frequent maintenance.
The optical encoders used incandescent lamps, which were large in size and had
limited life expectancy. The resolvers could offer better resolution and
accuracy, but were very expensive due to the decoding electronics required.
However, recent technological developments have brought significant
improvements to these encoders with optical encoders and resolvers more
commonly used in industry today. With the introduction of the cost effective
Smart-Encoders by Autotech, there will be a paradigm shift in the selection and
use of encoders for specific applications.
