Incremental encoders are position feedback devices that provide incremental counts. Thus, an incremental encoder provides relative position, where the feedback signal is always referenced to a start or home position. For incremental encoders, each mechanical position is uniquely defined. The current position sensed is only incremental when compared to the last position sensed.
Avago incremental encoders are also called optical encoders, optical incremental encoders, or magnetic incremental encoders because they utilize optical technology or magnetic Hall effect sensing technology. Avago supplies both optical transmissive incremental encoders and optical reflective incremental encoders.
Avago incremental encoders are available as encoder modules for integration by the user or as complete housed or kit incremental encoders.
