Absolute rotary encoders  identify every point in a  movement through a  unique digital signal. Due  to their ability to assign an  exact, unique position  value to every linear and  angular position, absolute  rotary encoders have  become one of the most  important links between  the mechanical system and  the control system.

  As specialists in optical  rotary encoders, we have  also acquired a reputation  for field bus systems in  addition to the traditional  technologies of parallel  and serial data transfer.

  Through the continous  further development of  electronic interfaces and  through the extended  functionality, which now  goes far beyond the  delivery of a position  signal, our intelligent  sensors take over part of  the control system's job,  thus supporting the  general trend towards  decentralized automation.  Programmable  supplementary functions  and comprehensive  diagnostic functions also  help to reduce the need for  other components and  enhance the machine's  availability.
