SiO2 Phase Cable Assemblies

Home > Products > Assemblies > Phase Critical Assemblies > Sio2 Phase Cable Assemblies

 

 

SiO2 Semi-Rigid cable assemblies provide formable phase stable performance using materials developed specifically for use in applications where repeatable phase performance is critical. In short, matched TMS SiO2 cable assemblies exhibit the best phase-tracking performance available.

 

Work with your Times Military/Aerospace Regional Applications Engineer to get the SiO2 Semi-Rigid assembly configurations you need.

 

The SiO2 product line consists of cables sized from 0.090 to 0.270 inches in diameter.
