Product Code : Rotary Solenoid
Brand Name : Rotary Solenoid
Rotary solenoid is an electromechanical device used to rotate a ratcheting mechanism when power is applied. Rotary solenoids produce a rotational movement when either energized, de-energized, or a change in the polarity of an electromagnetic field alters the position of a permanent magnet rotor. Their construction consists of an electrical coil wound around a steel frame with a magnetic disk connected to an output shaft positioned above the coil. When the coil is energized the electromagnetic field generates multiple north and south poles which repel the adjacent permanent magnetic poles of the disk causing it to rotate at an angle determined by the mechanical construction of the rotary solenoid. When power is removed, a spring on the disk rotates it back to its starting position, also pulling the core out of the coil. Commonly available rotary solenoids movements of 25, 35, 45, 60 and 90o.
