A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, ...

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 ...

Renishaw (www.renishaw.com) has developed new linear encoders that feature a special stainless steel scale, ultralow ±30 nm cyclic error, patented filtering optics and ±4μm accuracy to deliver the ...

Offering high reliability and safety, the LIC 4000 series linear position encoders integrate a multi-substrate scale tape with absolute encoder technology, which provides position immediately at ...

Featuring a postage-stamp-sized scanning unit along with high accuracy, Heidenhan’s incremental exposed linear encoders will likely fit the needs of stage manufacturers or anyone using linear motors ...

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 ...
