rotary solenoids

Versatility of the Rotary Series

Johnson Electric is the world leader in Rotary Solenoid technology. Rotary solenoids are electromechanical devices that convert linear motion to rotary motion by virtue of three ball bearings that travel down inclined raceways.

How Rotary Solenoids Work:

When the coil is energized, the armature assembly is pulled towards the stator and rotated through an arc determined by the coining of the raceways.

Our 3 Ball Race rotaries are capable of withstanding a high G load shock without worrying about accidental actuation thanks to the uniquely designed helical raceways and tri-ball bearing setup.

Our standard design is capable of -55°C to +80°C ambient temperatures and the high-temperature design is capable of up to 200°C.

These extremely high-speed actuation devices provide very long-life operations for the most challenging applications.
