0: worm gear reducer;

1: Planetary reducer.

Code points 5, 10, 11, 13, 14, 15, 16 and additional special code selection refer to corresponding code points of 2SQ3.

1.3. Structural features

2SQ3 series partial rotation electric actuator is composed of 2SA3 series multi rotation electric actuator and secondary reducer. The multi rotation movement output by 2SA3 series multi rotation electric actuator is reduced by secondary reducer, and then the rotation movement of a certain angle is output.
