Johnson Electric’s linear open frame solenoid technology consists of an open iron frame, an overmolded or taped coil, and a movable plunger in the center of the coil. This platform is available in AC and DC versions and in two frame styles, the C Frame style, in which the coil is enclosed on side, and the Box Frame style in which the coil in enclosed on two sides. The Box Frame style provides slightly higher force output and higher resistance to environmental conditions. Open Frame Solenoid technology offers an economical design for high volume applications, continuous or intermittent duty, and on/off operation common in applications such as vending machines and automated door locks. This technology offers life up to 5 million cycles and a variety of size, force and stroke options. Custom designs can significantly increase life performance.

Johnson Electric’s SoftShift linear solenoids provide slow, smooth position control or high speed snap action operation. SoftShift solenoids have a unique construction which allows easy transition from snap action to variable positioning. Using the same power, starting force is three to five times higher than standard solenoids at the fully de-energized position. This is advantageous for starting inertial loads or detent mechanisms, and for conserving electrical power. This solenoid offers quiet operation, high power density, and a variety of sizes. Custom engineered solutions ensure that exact application requirements are met. With life of 10 million cycles, the SoftShift platform is ideal for applications requiring closed loop velocity and position control.

Johnson Electric’s Ultimag® rotary actuator technology offers a bidirectional, center return function not found in traditional rotary solenoids. The Ultimag platform is substantially faster than other solenoids, and can be operated in an on/off mode or proportionally, in both open and closed loop systems. Ultimag actuators offer a 45° stroke; however, the design is capable of a maximum stroke of 160°. For shorter strokes, electronic or mechanical stops can be used. This technology is ideal for applications requiring high speed and high torque motion control often found in industrial, business technology and medical applications.

Johnson Electric’s BTA actuator platform offers high speed controllability in rotary stroke applications. The BTA has a single phase coil with three stator poles and matching rotor pole. When the coil is energized, the poles align along the flux path. The three pole design allows a stroke of up to 45°. Since BTA technology does not require full stroke actuation, stops can be used to attain maximum life as well as optimum stroke / torque capacity.

Using simple pulse width modulation to control coil current, the BTA allows open or closed loop velocity and maximum position control. The BTA platform offers quiet operation due to the soft, shock-free cycling which eliminates the noise associated with end-of stroke mechanical stops. Very quiet operation, long life in excess of 100 million actuations and high power density make the BTA product family ideal for high speed, high throughput diverting and sorting applications that require low noise and zero downtime.

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.
