　　Rotary encoder application is very extensive that many machines will have a rotary encoder shadow. Because the main role of the rotary encoder is provided when the device is running the underlying code to support the machine is running, make sure that between the member and the member the interface between the more remarkable. So choosing the right type rotary encoder is very important!

　　Then, the rotary encoder selection should pay attention to what it?

　　1. Select a suitable rotary encoder must consider the cost of the product allows the homing of whether the power is turned on, control speed, immunity to interference and so on.
  2. The rotary encoder selection, to consider when choosing accuracy resolution. Taking into account the assembly of machinery and precision requirements based on the cost of the machine to select the most appropriate models use 1/2 a 1/4-accuracy resolution integrated mechanical precision.
　　3. The rotary encoder selection, to consider the size of the space, to consider the status of the installation space by the selected axis (hollow shaft lever shaft type)
  4. The rotary encoder selection, allow the load to be considered axis. Taking into account the different installation methods different axial load state, and mechanical lifetime.
  5. The rotary encoder selection, consider the maximum allowable speed, selected according to the maximum speed when using mechanical selection.
  6. The rotary encoder selection, to consider the highest frequency response, according to the maximum speed of decision assembling mechanical devices in use. Maximum response frequency = (speed / 6O) X Resolution
  7. The rotary encoder selection, to consider the protective structure. Selected protective structure according to dust, water, oil, on the extent of use of the environment may be.
  • Dust: IP50
  • water, oil: IP52 (f), lP64 (f) (anti-drip, anti-oil)
  8. The rotary encoder selection, start to consider rotating shaft torque. To understand clearly the driving source torque how much?
  9. The rotary encoder selection, consider the output circuit mode. To consider the posterior segment of the machine is connected, the signal frequency, transmission distance and noise environment. When long-distance transmission, to select line driver.
