By effectively sensing and digitizing linear position change, linear encoder provide proper measurement and feedback to control systems. Linear encoder is also used to measure counts per distance, lines per distance and linear measurement range. Encoders are of two types absolute encoders and incremental encoder, depending on their position signals. Unlike the incremental encoders the absolute encoders has the ability to create a unique position signal that is available anywhere along travelling.
manufacturers of linear encoder today are constantly upgrading the production of these linear encoders so that they perform effectively with a high resolution and provide faster and accurate results.
