Definition
Glass-to-Metal Connectors (GTMCs) are specialized electronic components designed to create a hermetic seal between a metal shell and a glass insulator. These connectors provide a highly reliable, impermeable barrier that maintains functionality under extreme environmental conditions, such as high pressure, wide temperature variations, and corrosive atmospheres.
GTMCs are engineered for high performance and durability, making them essential in applications that demand precision, longevity, and stable electrical performance. They are commonly used in sectors including aerospace, defense, medical, industrial, and automotive electronics. Key product types include:
- Power Feedthroughs: Designed for high-voltage and high-current applications, ensuring minimal electrical loss and reliable operation under extreme stress.
- Instrumentation Feedthroughs: Used for precise measurement instruments, providing reliable signal transmission and resistance to environmental factors.
- RF Feedthroughs: Specialized for high-frequency signal applications, maintaining signal integrity in complex electronic systems.
GTMCs utilize advanced sealing technologies that match the thermal expansion of metal and glass, such as Kovar-to-glass, stainless steel-to-glass, and titanium-to-glass seals, ensuring long-term hermeticity.
