Encoders turn mechanical motion into an electrical signal that is used by the control system to monitor specific parameters of the application and make adjustments if necessary to maintain the machine operating as desired.
A rotary encoder using optical sensing technology relies on the rotation of an internal code disc that has opaque lines and patterns on it. The disc is rotated (hence the name rotary encoder) in a beam of light such as an LED and the markings on the disc act as shutters blocking and unblocking the light.ncremental optical encoders are the simplest and most commonly used. The encoder provides information about the instantaneous position of a rotating shaft by producing one square wave cycle per increment of shaft movement.
