SoftShift air damper

The Smooth Actuation of the SoftShift Series

August 27, 2021

Johnson Electric’s SoftShift linear solenoids provide slow, especially smooth position control or high-speed snap-action operation.

SoftShift solenoids have a unique construction that allows easy transition from snap action to variable positioning. Using the same power, the starting force is three to five times higher than standard solenoids at the fully de-energized position, which is advantageous for starting inertial loads or detent mechanisms and conserving electrical power.

This solenoid offers quiet operation, high power density, and also a variety of sizes. Custom engineered solutions additionally ensure that exact application requirements are met. With a life of 10 million cycles, the Soft Shift® platform is especially ideal for applications requiring closed-loop velocity and position control.

The Powerful Ultimag® Series

August 13, 2021

Johnson Electric’s Ultimag® rotary actuator technology offers a bidirectional, center return function not found in traditional rotary solenoids.

Substantially faster than other solenoids, the Ultimag platform can operate in an on/off mode or proportionally, in both open and closed-loop systems.

Ultimag® actuators also offer a 45° stroke; however, the design can have a maximum stroke of 160°. For shorter strokes, you can of course use electronic or mechanical stops.

The Ultimag® Series was developed in response to application needs for higher speed and higher torque motion control components. This technology is also ideal for applications requiring high speed and high torque motion control.

rotary solenoids

Versatility of the Rotary Series

August 6, 2021

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.

Features and benefits

  • High Durability up to 50 million actuations
  • Large variety of sizes
  • Custom engineering for environmental and torque requirements
  • High-Shock Resistance
  • High-Temperature Resistance

Common Applications

  • Door Locking
  • Machine Vending
  • Industrial Automation
  • Medical Diagnostic Equipment

BTA - Brushless Torque Actuator

Extreme Speeds with the BTA Series

July 23, 2021

Johnson Electric’s BTA or Brushless Torque Actuator platform offers high-speed controllability in rotary stroke applications needed in material handling, valve control, high-speed shutter control, among others.

With a single-phase coil, stator bases, and a matching rotor pole, the design allows for a stroke of up to 45 degrees.

Since BTA technology does not require full stroke actuation, this product provides a much quieter operation due to the soft, shock-free cycling, eliminating the noise associated with end-of-stroke mechanical stops. With proper controls and application damping, it is possible to achieve exceptionally low dB levels.

The BTA product family is ideal for high-speed, high throughput diverting and sorting applications that require low noise and zero downtime for maintenance.

With the BTA series running at extremely high speeds, it works best in applications that require millisecond actuation speeds.
