Absolute Rotary Encoder HEIDENHAIN EQN1325

Absolute Rotary Encoder HEIDENHAIN EQN1325


Feature:
A Solid Shaft Absolute Rotary Encoder, also called a absolute 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 shaft making them angle transducers. The output of incremental encoders provides information about the motion of the shaf, which is typically further processed elsewhere into information such as speed, distance and position.
Application:
Absolute encoders are used in many applicaions that reauire precise shat unlimited rotaion-incuding industrial controls. robotics. Specia purpose photographic lenses,computer input devices (such as optomechanical mice and trackballs), controlled stress rheometers, and rotating radar platforms.
