Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

The safety encoder precisely records the movement of components such as axles, crane arms, and tipping skips. From this data, ...

Because they have higher resolution and accuracy, these encoders are often used in applications that need high precision, ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...

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 ...

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 ...

Because encoders limit the number of controls required to increase functionality, they reduce the real estate needed in a given piece of equipment and, in turn, can reduce the point of focus or ...

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 ...

Every encoder-based motion-control axis, such as a servo motor or step motor, must know where it is to be accurate. If it doesn’t, it will never reach its target position. But the encoder must first ...

The most obvious engineering goal of an encoder is to get the best picture and audio quality per bit used. The other significant objective is to keep down the total cost of ownership. Factors that can ...
