HIGH DEFLECTION MOUNTS: VHC Series

High deflection shock and vibration isolators for medium-weight sensitive equipment.
Barry VHC-Series mounts are special purpose, mid-frequency isolators designed to protect sensitive equipment when high level shock and vibration inputs are expected. Typical applications include electronic equipment installed in mobile equipment subjected to off-road environments.

Natural Frequency	12-20 Hertz
Transmissibility at Resonance	5.0 Max. (Barry LT Compound) 10.0 Max. (Neoprene)
Resilient Element	Barry LT Compound or Neoprene
Standard Materials	Steel (Grounding Strap Beryllium Copper)
Weight	4.0 lbs.

Dimensions and Performance Characteristics
VHC

Applications

Ground vehicle electronics
Shipboard equipment
Shipping containers
Equipment installed in transportable shelters

Features

Buckling design
Steel construction
Compression to shear stiffness ratio 2:1
Designed to carry static loads in the axial direction, but can accommodate dynamic inputs in the radial direction
Attenuates 18" freefall shock input to approximately 12g's

Benefits

Large deflection capacity provides superior shock attenuation
Can be used as stabilizers for tall equipment packages
Maximum loads apply when mount will be subjected to an 18" freefall. Larger loads can be accommodated for less severe shock inputs.

Load Range

4 load ratings to 145 lbs. per mount

Environmental Data

Barry LT (low-temperature) Compound, which is ideal for military applications, operates between -67ºF and +180ºF (-55ºC to +82ºC) and is resistant to fungus and ozone.
Neoprene has an operating temperature range of -20ºF to +180ºF (-30ºC to +180ºC) and resists oil and ozone.
