IHC3808 Series Hollow-Shaft Incremental Rotary Encoder

Feature
A hollow encoder, also called a  hollow shaft encoder, is an electro-mechanical device that converis the angular position or motion of a shaf or axleto an analog or digital code.
There are two main types: absolute and incremental (relative). The output of absolute encoders indicates the curent position of the shaftmaking them angle transducers. The output of incremental encoders provides information about the motion of the shaf, which is typicallyfurther processed elsewhere into information such as speed, distance and position.

Application

Automatic control,measurements,robotic X-Y labor and printing machines.

High reliability,long life,strong anti-interference ability and wide range  oftemperature adaption.

Rotary encoders are used in many applicaions that reauire precise shat unlimited rotaion-incuding industrial controls. robotics. speciapurpose photographic lenses,computer input devices (such as optomechanical mice and trackballs), controlled stress rheometers, and
rotating radar platforms.
