7mm

SV Microwave offers 7mm connectors and components. 7mm connectors are highly durable and therefore appropriate for repeatable mating and de-mating, making test and instrumentation their primary application. The 7mm connector is also the preferred connector for other demanding applications, such as metrology and calibration.

7mm coaxial connectors are air dielectric, have a low VSWR and feature a sexless coupling mechanism that permits any two 7mm connectors to mate.

Features & Benefits
  • Interface dimensions minimize distortion and deterioration of the mating surfaces  
  • Fixed bead-contact assembly prevents transmission of mating torques to circuit elements  
  • Mating sequence touches outer contacts before center contacts, eliminating female center contact damage during mating  
  • Plug coupling nut extends beyond the male center contact, protecting the contact while not mated

 

Applications
  • Instrumentation
  • Military
  • Satcom
  • Cable Assemblies
  • Test and measurement
