ROE-E Series is an angle-measuring sensor device which is used to detect angular velocity. It can convert the angular velocity that is input into the shaft to the corresponding pulse numbers following optical communication principle. Small size, high precision and reliable performance are its features. ROE-E Series is usually used for detecting speed, rotation direction and angular displacement.
