Wherever and whenever possible, the world is transitioning from analog to digital, and in machine tools, we are seeing the move toward digital axes in drive technology. The Heidenhain Corporation (www ...

Rotary encoders convert a shaft's angular position into an analog or digital code. They are characterized as either incremental or absolute devices: incremental encoders are capable of tracking motion ...

An interesting trend in industrial motion control has been the replacement of self-contained encoders (rotation sensors with their own housing, bearings and shaft) with modular or “kit” encoders.

An absolute rotary encoder determines the angular position of a shaft on the basis of a static reference point. They are sensors that generate digital signals that correspond to the position in ...
