Product Overview


Hermetic Glass to Metal 4-pin Feedthroughs Connectors

Product Description

Glass to Metal Hermetic Feedthroughs/Seals /Headers/Connector is also called Glass insulator.They are one of the most critical components for seal assemblies. Dielectrics and supporting materials are made of glass with low dielectric constant and low dielectric loss. Both inner conductor and outer conductor are made of Kovar alloy and sintered at high temperature. The surface is plated with gold. Inner conductor has a variety of termination styles such as gold wire bonding, soldering and mating etc. Glass insulators are small, lightweight, hermetic, reliable and have been widespread in electronics manufacturing industries recent years.hermetic seals.jpg



-Small size



-High reliable

-Inner conductor: Gold wire bonding, soldering and mating method for choice

Glass insulator was mainly used for the transmission of microwave signals, power signals and control signals between modules and modules, modules and components that request hermetic sealing, can be used with SMA, millimeter wave products; They are one of the most critical components for seal assemblies. Glass to Metal Connector

We have over 1,000 types of glass beads/glass insulators/ feedthroughs from 1-pin to 9 pin with 1-3 rows for choice, if the product you are using is not found, please contact us for catologs. Custom dimensions is accepted.
