Hermetic Glass to Metal Seal Connectors RF Feedthroughs Extend Insulation

  • Hermetic glass to metal seal ensures leak-proof and reliable connections in extreme environments
  • Extended insulation provides enhanced protection against signal interference and contamination
  • Optimized for RF feedthrough applications, ensuring minimal signal loss and high-frequency stability
  • Ideal for aerospace, defense, telecommunications, and high-reliability industrial applications
  • Designed for high-performance, long-term durability in high-frequency, high-temperature conditions

Glass-To-Metal-Seal-Connectors

Glass to Metal Hermetic RF/DC Feedthroughs/Seals /Multi-pin Headers /Connector is also called Glass insulator. They are mainly used to transmit microwave signals, power signals and control signals between modules and modules, modules and components with gas sealing requirements. They are one of the most critical components in sealing components. The glass with low dielectric constant and low dielectric loss is used as insulating and supporting material. The housing and conductor is made of Kovar alloy that sintered under high temperature, and the surface is gold plated. The centerconductor has a variety of termination styles such as gold wire bonding, soldering and mating etc. Glass insulators are small, lightweight, hermetic, high reliable and have been widespread in electronics manufacturing industries in recent years.

Structure

Glass insulator is composed of three parts: outer conductor/shell, glass medium and center conductor/pin.Its basic structure is shown in the figure.
