Magnet-Schultz Rotary Solenoids: Unlocking precision and efficiency for applications

By Staff Report August 9, 2024 7:04 pm IST

The DC rotary solenoid GDA converts the linear magnetic force to a rotary movement. They are the solution for a quick rotary movement of max. 110 degrees.

For applications needing a fast rotary motion within a maximum range of 110 degrees, the conventional approach involving an engine, gearbox, and limit switch may need to be more complex for needs. Magnet India offers rotary solenoids that can be an ideal solution for your requirements. These solenoids come in different variants, including ON/OFF functionality, proportional rotary solenoids, and options with or without a return spring. 

These solenoids find applications in various fields, such as optical devices, medical devices, packaging machines, food technology, and apparatus construction.

Overview of the range

Long-life rotary solenoid-type GDA: The GDA DC rotary solenoid transforms linear magnetic force into rotary motion by utilizing an armature bearing to support the axial component of the magnetic force. It is important to note that no linear motion occurs during the rotary movement. When supplied with voltage, ON/OFF rotary solenoids rotate the drive shaft to the end position. Due to the increased torque characteristics, these solenoids do not allow for magnetic force or rotation angle control.

It comes in sizes (Ø): 25 mm, 35 mm, 50 mm, 60 mm, 75 mm with Rotation angles: 95°, 65°, 35° and torque: 0.16 Ncm – 195 Ncm. Its features include clockwise and anti-clockwise versions through shafts protruding on both sides with and without return springs.

· Electrical connection via free, flexible lead ends 

· Fastening via tapped holes at the end faces

· Protection class: IP20 and Voltage type: direct current, DC.

Proportional rotary solenoid-type GDR: In contrast to the ON/OFF rotary solenoids GDA, the GDR proportional rotary solenoid operates based on an electrodynamic principle. It exhibits a proportional relationship between torque and current, maintaining a consistent torque throughout its entire operating range. This characteristic allows for implementing force- and position-controlled actuators by utilizing suitable controls and rotation angle sensors.

It comes in sizes (Ø): 35 mm, 50 mm, and 75 mm with a Rotation angle of 110° and torque: 2.1 Ncm – 85 Ncm. It includes the following features.

· 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 and voltage type: direct current, DC

· Option: versions with programmable hall sensor, flange option of a return spring.
