RS91 series are three channel/two channel optical incremental encoder modules. Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package.  Due to a high collimated light source and a precision photodetector array, with a matched codewheel, the module provides the information of rotary motor . 

RS91series have lots of CPR options based on optical radius(ROP)=11mm, standard CPRs：100，200，256，300，360，400，500，512，600，1000，1024,2000，2048,2500.
