Note the use of optical encoders！

The optical encoder Caution
1, the mechanical part
     1) measuring the length or angle measurement;
     2) shaft installation form;
     3) use of the environment, dust, moisture, vibration, shock.
2, the electrical part
     1) connected to the output of the receiving section;
     2) signal form;
     3) resolution requirements;
     4) control requirements.
     * Absolute encoder problem
     * Absolute encoder: absolute position of each unique, interference, without power-down memory.
