In the hermetic and vacuum-sealed industries, terms such as Vacuum Feedthrough, Electric Feedthrough, Glass-to-Metal Feedthrough, and Ceramic-to-Metal Feedthrough are often used interchangeably. Despite their varied names, these components share a critical function: facilitating the transmission of electrical currents while maintaining an airtight seal.
What Are Hermetic Feedthroughs?
Hermetic feedthroughs are essential in applications requiring strict isolation from environmental contaminants such as air, gas, or moisture. The term “hermetic” refers to the ability to create an airtight barrier, ensuring no gas or liquid leakage. In interconnect systems, hermetic seals and feedthroughs are engineered to prevent the passage of gases through pressure barriers. This technology is crucial in environments where maintaining a vacuum or specific atmospheric conditions is critical, such as aerospace, medical, and industrial applications.
Types of Hermetic Feedthroughs
Complete Hermetics specializes in designing and manufacturing a wide range of feedthroughs, including:
- Custom Hermetic Feedthroughs: Tailored solutions designed to meet unique application needs.
- Glass-to-Metal Feedthroughs: Reliable for high-pressure and high-temperature environments.
- Ceramic-to-Metal Feedthroughs: Ideal for medical probes and devices requiring high precision and durability.
- Multi-Pin Hermetic Feedthroughs: Offering multiple electrical connections through a single hermetic seal, improving efficiency in complex systems.
- Electrical Bulkhead Hermetic Feedthroughs: Designed for flange installation, these feedthroughs provide secure electrical connections across bulkhead barriers.
Applications and Durability
Hermetic feedthroughs are built to endure extreme environments. They are extensively used in submersible pumps, downhole drilling instrumentation, cryogenic medical devices, and exploratory implants. Their ability to withstand high pressures ensures consistent performance in critical applications such as surgical instruments and industrial machinery. The laser-welded and soldered designs enhance reliability and functionality across various demanding scenarios.
