Multi turn absolute rotary encoder

Multi turn absolute encoder. The encoder manufacturer uses the principle of clock gear mechanism. When the central code plate rotates, another group of code plates (or multiple sets of gears, multiple groups of code disks) are driven through the gear, and the number of turns is added on the basis of single cycle coding to expand the measurement range of the encoder. Such an absolute encoder is called a multi turn absolute encoder, which is also determined by the mechanical position, Each location code is unique and does not need to be memorized. Another advantage of the multi turn encoder is that due to the large measurement range, the actual use is often more abundant, so it is not necessary to find the zero point during the installation, and a middle position can be used as the starting point, which greatly simplifies the difficulty of installation and debugging. Multi turn absolute encoder has obvious advantages in length positioning, and has been more and more used in industrial control positioning.
