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. 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. These extremely high speed actuation devices provide very long life operation for the most challenging applications. With operating life up to fifty million cycles, a wide variety of sizes and custom engineering for life, speed, environmental conditions and torque requirements, the Rotary DC solenoid is ideal for a variety of markets and applications including door lock, vending machines, industrial automation and medical diagnostic equipment.
