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, ...

Optical or magnetic linear encoders are traditionally used to provide position feedback in applications with frequent product changes or and sophisticated machining. Linear encoders improve the ...

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 ...

HEIDENHAIN’s new LIP 6000 miniature linear encoder system, consisting of a scanning unit and glass scale, has the unusual capability to measure to 2 nm resolution with high speed of 4m/sec at long ...

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 ...

SICK has released safety-certified versions of its TTK70 and TTK50 magnetic absolute linear encoders with Hiperface° interface, widening the opportunities for accurate, absolute motor feedback systems ...

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