Proportional Rotary Solenoids Type G DR


Unlike the ON/OFF rotary solenoids G DA and G DC, the proportional rotary solenoid G DR works to an electrodynamic operating principle, featuring proportional relation between torque and current as well as a constant torque over the entire operating range. Therefore, by using an appropriate control and a rotation angle sensor, it is possible to realise force and position controlled actuators. 


Sizes (Ø): 35 mm, 50 mm, 75 mm
Rotation angle: 110°
Torque: 2.1 Ncm – 85 Ncm



  • Reversal of the direction of rotation by reversing the polarity of the supply voltage
  • Electrical connection via free flexible lead ends 
  • Fastening via tapped holes at the end faces 
  • Versions with attached rotation angle sensor to the measuring principle hall sensor 
  • Protection class: IP20
  • Voltage type: direct current, DC
  • Option: versions with programmable hall sensor, flange option of a return spring

Naturally, the rotary solenoid G DR may be also applied as ON/OFF solenoid. If the direction of rotation cannot be reversed by polarity reversal, a return spring can be flangemounted in analogy to type G DA.
