Actuators NEx, NEx-K, NEx-KA, NEx-V 

 

Direction of rotation 

−

  Viewing direction through the actuator towards the output shaft (threaded 

spindle) 

−

 

Clockwise rotation:

 

The output shaft (threaded spindle) rotates 

clockwise

 (CW). 

−

 

Counterclockwise rotation:

 

The output shaft (threaded spindle) rotates 

counterclockwise

 (CCW). 

−

 

Direction of rotation

 always refers to the 

output shaft

! 

 

 

Important information! 

The rotational direction of series NEx-K, NEx-KA and NEx-V is determined 
analogous to series NEx1 to NEx4 (see Fig. 5.12).
