M-232 Linear Actuator  

 

MP105E

 

Version: 1.2

5.1  General Notes on Installation 

  

 

NOTICE 

 

Cable break! 

A cable break leads to a failure of the linear actuator. 

  Install the linear actuator so that the cable is not bent or squeezed too severely 

during operation. 

  
  

NOTICE 

 

Increased friction! 

Lateral forces that affect the pusher of the linear actuator increase the friction on the 
internal drive components. Increased friction impairs the motion of the pusher and 
increases wear on the drive components. 

  Avoid lateral forces on the pusher of the M-232. 

  

 

NOTICE 

 

Heating up of the M-232 during operation! 

The heat produced during operation of the M-232 can affect your application. 

  Install the M-232 so that your application is not affected by the dissipating heat. 

  

 

INFORMATION 

 

Linear actuators with DC gear motors are equipped with integrated signal drivers for 

cable lengths of 

≤

10 m between linear actuator and motor controller.
