Encoder Incremental Optical Sensor
Encoder can be divided into absolute encoder and incremental encoder. Incremental encoder is relatively easier in realizing its function than absolute encoder. Its cost is lower than absolute encoder. The measuring range of incremental optical encoder is one turn(360 degree). After 360 degree, it will start from 0 again. Optical sensor has higher accuracy than magnetic encoder. The optical glass can provide the accurate position feedback.
