Autotech offers one of the broadest lines of encoders in the industry, from a tiny size 15 (housing diameter to be 1.5”), industry standard size 25 (2.5” dia), to explosion proof encoders and everything in between including built-in gear trains, along with wide variety of position sensing technologies, electrical characteristics and communication options. This section is written to provide a reference guide to selecting the right encoder for your application.
Many industrial control systems need position and speed feedback. In the initial stages, the encoders consisted of potentiometers, brush encoders, magnetic encoders and rarely optical encoders and resolvers. Each device had certain limitations. The potentiometers and magnetic encoders had limited resolution. 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.
The recent technological developments have brought significant improvements in the initial models. Today optical encoders and resolvers are more commonly used in industry. And with the introduction of cost effective Smart-Encoders by Autotech, there will be a paradigm shift in the selection and use of encoders.
