Rotary Optical Encoder is a sensor that converts machinery positional information into corresponding pulse numbers or digital data by photoelectric signals. Therefore, it can detect the speed, position, angular velocity, distance and counts information relating to mechanical machine or motor.

Delta ROE series provides precise positioning and speed sensor function, it can also be built inside of many kinds of servo motors, brushless DC motor (BLDC) or induction servo motors, converting rotary motion or position to electronic pulse numbers for phase change, speed and position detection
