Applications for Scientific and Custom Rotary Solenoids


Rotary solenoids are devices that are designed to convert axial motion into rotary strokes. They are known to be more resistant to shock and have higher toque as compared to linear solenoid.

These electromechanical devices are commonly used where a longer life is required and space is quite limited. When observed from the armature flange end, their energized rotation could be characterized as clockwise or counterclockwise. Most of these products also have a spring return that allows the armature to get back into its home position when power is removed.


Here at Brandstrom Instruments, we manufacture a wide range of miniature rotary solenoid shutters for thermal imaging and other scientific applications. Our solenoids and shutters deliver

exceptional performance in challenging applications, including soldier systems, aviation/aerospace systems, ground vehicles, and more.

Let’s take a look at some applications for three types of custom rotary solenoids:

1.Bi-Stable Solenoids

These bi-stable solenoids or bi-directional rotary solenoids serve as the switch controls that allow products to pass or get selected. They remove the need to return a spring and provide a faster and more efficient action.

2.Electro Optical Shutter

These electro optical shutter rotary solenoids are typically used in laser applications or for thermal imaging that require fast and reliable shutter action.

3.Latching Solenoids

Latching solenoids require permanent magnets in order to maintain their position and they’re used in low-duty cycle applications (e.g. door locks) where the energized position has to be maintained for an extended amount of time.

Bottom Line

When you’re selecting rotary solenoids for your application, you must consider critical requirements like axial stroke, rotary stoke, and response time. The axial stroke is essential for the axial travel of the device during actuation, the rotary stroke refers to the full rotary travel in angular units, whereas the response time is the time it takes to move full stroke when faced with no-load conditions.
