Introducing the next generation of HALT vibration systems.

Worlds first 6 MDoF (Multi Degree of Freedom) Spherical random, compact Electro-Dynamic (ED) repetitive shock. This new vibration HALT system give faster results. The Next Great HALT Breakthrough from King Design. This replaces the standard AIR impactor with an Electro Dynamic (ED) impactor with precise time and phase control. Producing low frequency vibration form the 20-2000 Hz.

ED-HALT generates force vector in any direction and magnitude

Since each impactor is electric there is complete control over timing, impact force, and Phase giving complete control over force vector and frequency. This allows for the true spherical ball of imparted force. With true spherical ball you are testing all direction of vibration at same time without having to rotate product

Mult Zone View

Sized to Fit

ED-HALT comes in a variety of table sizes to accommodate your varying testing needs.

  • KD-ED-HALT 12" x 12"
  • KD-ED-HALT 18" x 18"
  • KD-ED-HALT 24" x 24"
  • KD-ED-HALT 30" x 30"
  • KD-ED-HALT 36" x 36"
  • KD-ED-HALT 48" x 48"

The ED-HALT system can be integrated into your existing chamber or as a stand alone vibration system with or without a sound enclosure. This gives your the most flexibility and cost effectiveness to get your product tested.

Spherical Force Cector

Multi Zone Control

Ability to control each zones impactors force, phase, and timing. Giving you control over each zones force vector, amplitude, and rotation. Since each impactor is controlled electrically this gives precise control over the vibration imparted into the table. This enhances ability to find faults in products for shorter development time.

Direction Control

Follow NAVMAT Profile

ED-HALT has precise control over time and phase producing Low Frequency 20—2000 Hz vibration much closer match to NAVMAT profile. This system can help reduce your development time as well as costs.


ED-HALT test procedure: most effective test mode

1.Spherical mode
2. Random mode
3.Co-axial mode (X-Y axis: 50%, Z axis: 100%)

Select the ESS spectrum and property Stress

  1. Operation limit --- use step stress to find the operation limit of product, find problem, improve it, until the X2 of ESS gRMS. (recommend use condition monitoring with high test coverage )
  2. Destructive limit --- increase the step stress to find the destructive limit---or table limit.
  3. ED-ESS on production line. Use the selected ESS spectrum for stress screen. Use test failed data results to fine tune the screen stress. Effective screen stress to screen out weak product and not cause too much damage to product (safety of screen stress). At most 10 or 30 continuous screen cycles. To avoid screen stress too high (Already out of regular failure mode to create unreasonable damage), or too low strength.
