An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

From pan-tilt-zoom cameras to the most highly sophisticated mini robots on the market, a wide array of today’s technologies incorporate some form of motion control system. At the heart of these ...

Today's consumer devices are defined by portability. However, where these designs incorporate movement, how do product engineers integrate feedback? In portable medical applications, reflective ...

Encoders are integral parts of motor-control systems that sense mechanical motion, then generate digital signals in response to that motion. The trend today is to create smaller mechanical and ...

The DWS60 Draw Wire encoder system provides linear motion feedback over long distances for a range of industrial applications. Key features include an extended measurement range capable of measuring ...

It’s easy to take feedback devices for granted. However, the impact this seemingly minor component can have on a system’s ...

Last year, Automation World examined the differences between accuracy, resolution, and precision in the encoder world. And while understanding the differences among these terms is important to ...
