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 ...

This is the first of a two-part series. Part 2 can be found here. Encoders play an integral role in almost every mechanical system that involves motion monitoring or control. There are a variety of ...

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 ...

Optical or magnetic linear encoders handle high-res needs in dirty jobs. Linear encoders help minimize errors in motion transmission such as backlash, hysteresis, abbe errors, ball-screw thermal ...

Linear motion positioning stages are found in many applications from material handling and assembly to inspection and testing and employ many different technologies. Just looking at the different ...
