Glass-to-Metal Seals and Feedthroughs

When To Choose Glass-to-Metal Feedthroughs

Feedthroughs are an indispensable part of most commercial electrical applications and their accuracy is critical to its success. When working in aerospace, defense and other arenas where extreme conditions are the norm and high reliability is vital, feedthrough performance is even more vital. These are cases where glass to metal hermetic feedthroughs make the most sense. Here are a few other applications where glass-to-metal sealed feedthroughs are the ideal choice.

Medical Applications

Perhaps no environment could be tougher than the human body. When a device must be implanted, a glass-to-metal hermetic feedthrough is the best choice. This type of airtight feedthrough prevents diffusion of gasses and keeps electrical components from corroding when doing so could spell life or death.

Automotive Applications

If a sensor has ever triggered your vehicle’s check engine light, you know how important it is that they work properly. Glass-to-metal feedthroughs are ideal to ensure sensors measuring everything from flow to pressure can function properly.

Industrial Applications

Glass-to-metal seal feedthroughs are commonly used in critical industrial applications, blocking the effects of high temperature and damaging chemicals. In this case, hermetic feedthroughs can also prevent electronic failure caused by humidity or pressure.

Hermetic feedthroughs have countless applications in defense, medical, aerospace, and other fields. Glass-to-metal manufacturing creates the most reliable performance.

Getting the Right High Vacuum Feedthrough

A hermetic feedthrough must be secure enough to prevent leakage, even the smallest amount. It has to maintain a vacuum under certain conditions, which are different for every application. Fortunately, there are three main types of feedthroughs which operate in hermetic vacuums:

  • Low voltage
  • Water-cooled and RF
  • High-voltage

We have the experience to design and develop a high vacuum feedthrough to achieve the proper hermetic seal for your application. Let us work within your specifications to create what you need to move forward with your system.

Attaining a hermetic seal with a high vacuum feedthrough can be done using a glass-to-metal or ceramic-to-metal design. The properties of your project and its use will determine the best materials for its design. We have multiple options to meet the standards of excellence in your industry. Our engineers specialize in developing the right hermetic system to fit your needs.

Because we have worked with many different industries, we know how to create the product that fits medical equipment or satellite systems. Our engineers have worked with the military, aerospace development, and pharmaceutical companies. Every hermetic system with a high vacuum feedthrough is tested before use to ensure quality control. Whether you’re looking for a prototype or manufacturing of multiple hermetic seals, our team can make it happen.
