Hermetic coaxial connector

Our hermetic coaxial connectors are engineered to provide airtight, moisture-resistant, and high-reliability connections for RF, microwave, and high-speed digital systems. Designed with glass-to-metal seal (GTMS) or ceramic-to-metal seal technology, each hermetic RF connector maintains stable performance even in extreme temperature, vacuum, and high-pressure environments.

These hermetically sealed coaxial connectors are available in various interface types, including hermetic SMA connectors, hermetic BNC connectors, hermetic N-Type connectors, and custom designs. They offer excellent VSWR, minimal insertion loss, and consistent 50Ω or 75Ω impedance.

Applications

  • Aerospace & Defense: Radar, avionics, satellites

  • Telecommunication: Outdoor base stations, microwave links

  • Test & Measurement: Hermetically sealed RF feedthroughs for vacuum chambers

  • Industrial & Medical: High-reliability RF systems in harsh environments

  • Vacuum Systems: Particle accelerators, scientific research equipment
