In this article posted on Motion Control Tips, a Design World resource, Jeff Smoot, CUI’s VP of Application Engineering and Motion Control, takes a look at the three most common encoder technologies and explains how capacitive technology blends the necessary accuracy and ruggedness needed to perform under severe industrial conditions.
The article begins, “Encoder applications are all around us, from BattleBots to the Mars Rover, large construction vehicles to semiconductor manufacturing equipment, and in numerous medical and military applications. In short, wherever there is motion, an encoder is sure to be found. They might not have the same glamor as some of the products into which they go, but they’re critical in today’s complex and sophisticated motion control systems.”
Jeff Smoot goes on to discuss the three types of encoder technologies, outlining where they do and do not excel. He then notes how the digital nature of capacitive technology is taking encoder design into the 21st century in the age of IoT connectivity.
