New vapor barrier RF coaxial assemblies by HUBER+SUHNER take flight

The future of military aviation is complex and ever evolving.


Emerging markets such as space, supersonics, hypersonics, and Advanced Air Mobility (AAM) have grown more than ever before. These markets are poised to change the aerial landscape for aerospace and defense in the coming years. The one thing that these markets are all going to need is exceptional signal integrity and performance, under the most strenuous atmospheric changes.


Military aircraft go through rapid acceleration, temperature, pressure and altitude changes. When they perform under these most challenging conditions, there is a risk of ingress of water vapor, fuels, oils, chemicals and other hazardous contaminants. Any of these alone or in combination, could lead to performance decay downtime and cable degradation over time. This in turn means increased maintenance, repair, overhaul and overall costs to operate.


A vapor barrier that’s built within coaxial assemblies on board the aircraft, can provide protection and prevent moisture ingress. 

Introducing the HUBER+SUHNER SUCOFLIGHT™ 100 series

The SUCOFLIGHT™ 100 series from HUBER+SUHNER is an all-new portfolio of hermetically sealed and MIL-qualified vapor-barrier radio frequency (RF) coaxial assemblies. They’ve been specifically designed and engineered for military, airborne, and other demanding applications. Vapor barriers can restrict access to all manner of contaminants in-flight, from water vapor in all forms, to jet fuel and propellants, chemical bodies, etc. The SUCOFLIGHT™ 100 series of cable assemblies from HUBER+SUHNER is therefore a vital cable solution for critical airborne applications and can be invaluable in airframe, Active Electronically Scanned Array Radar, electronic warfare pods, avionic upgrades, as well as Maintenance, Repair and Overhaul (MRO).


Available as two variant coaxial assemblies SUCOFLIGHT™ 123 and SUCOFLIGHT™ 134, these new solutions are MIL-qualified (MIL-T-81490) and are available with standardized connector entries with field-replaceable connector interface heads, offering interchangeability between different cables.


Features

  • Operational longevity in severe environmental conditions 
  • A VLN interface that provides a hermetic transition from cable to field replaceable connector heads
  • Low insertion loss and outstanding shielding effectiveness
  • All connectors designed with safety wire holes 


Benefits

  • MIL-T-81490 qualified for the rigors of harsh military air applications
  • High voltage rating for high peak power applications (through a specialized wedge feature design on VLN interface)
  • End-to-end expertise at HUBER+SUHNER offering a one-stop shop solution
