Optical encoder

An optical encoder is a type of motion sensing device that uses light that shines through a disk to detect the motion of an axis. The encoder provides feedback based on the light interruption.

More information about Optical encoder

A light beam emitted from an LED passes through a code disc. The light beam is picked up by a photodetector unit, also called a photodiode set or a photosensor. The photodetector unit responds to the light beam and produces a sinusoidal waveform, which is converted into a square wave or a pulse train. This pulse signal is simple: light = on no light = off The pulse signal is then sent to the control unit via the electronic card. The control unit then sends the signal to produce the correct function.
