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 ...

Renishaw recommends its Fortis enclosed linear absolute encoder series for use in harsh environments, such as around machine tools. The Fortis design uses Renishaw’s Resolute encoder technology. It ...

Linear encoders are the sensors that detect linear movements as absolute position values without establishing a physical contact with the object. Linear encoders play a crucial role in determining the ...

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, ...
