FSI/ Kwangwoo hollowshaft encoders continue to be a popular item in 2012. Encoders convert motion into digital information for display or control based on motion variables such as position, speed, length, RPM, etc. The advantage to using a hollowshaft encoder is that access to the end of a shaft is unnecessary. The encoder simply slides over the shaft and is mounted on it like a doughnut (as pictured). For more information, visit
