The introduce of the CORE-BLOCK of the encoder！

• Encoder axis
  

Shaft equipment circular motion will direct the (hollow shaft encoder) or through by the coupling (solid shaft encoder) transmit to the internal of encoder to realize detection. Axis requires good corrosion resistance and low TIR, the TIR usually is 0.001 "or lower.

• Encoder shaft seals 
  

Without shaft seal, encoder bearing and optical channel are polluted by dust, pollutants and moisture at surrounding. Good lubrication of the rotary lip shape shaft seal in encoder provides the best environment protection in the process of the whole life.

• Encoder optics and electronic components
  

Optical integration components combine with the electronic circuits generated by the rotation of the rotary encoder produce a change amplified signal, then converted into digital stream of pulses, provide for the use of the counter or controller. Electronic as the center of the Compact disc accuracy is higher than±1/40th during one cycle.

• Encoder shell and coupling
  

Encoder housing provide mechanical protection for the internal components to avoid the dust and humidity. Coupler will connect the encoder outside signal so as to keep the encoder environment protection. All entrance encoder, including screws should use O-rings seal, in order to achieve the best environmental protection ability.

• Encoder bearing
  

Bearing and shaft (or hollow shaft encoder tube) provided a rotational support platform for encoder and bearing the encoder disc. The most accurate encoder using double pre-installed bearing components.

• Encoder working condition
  

Encoder works environment technical standard indicates that encoder manufacturers can normal operation under the regular working environment condition. Carefully check the bearing and temperature range, generally no specific parameters to define these, if the value is very important for your application, then you need to make sure that these parameters can meet your application.
