The Magic of Hermetic Feedthroughs

Have you ever wondered how electronic components or medical equipment can be created with an airtight seal?  Perhaps you have looked at computer parts and wondered how they could stay free from moisture and corrosion. It is all due to hermetic feedthroughs and seals


Hermetic is defined as complete. That means a hermetic seal is waterproof, airtight, and completely self-contained. Depending on the materials used, the seals and feedthroughs can sometimes let air or oxygen pass through the closure. However, for the most part, the supplies are considered airtight. The most popular materials include rubber, glass, and plastics.


An example of feedthrough technology can be found in the way wiring is now sealed. Not only can the plastic coating cover the wires, but it can also protect each unit from variations in temperature, humidity, and pressure. Other types of feedthroughs can be found in vacuum chambers, signal wires, and sealed bulkheads. This special design can also allow for flexibility and prevents many common electrical problems. 


Mechanical stresses and high-endurance sealing issues can also be addressed by using hermetic feedthroughs and seals. In fact, hermetic seals are frequently used in medical equipment because of the high reliability of the high-voltage switches, vacuum applications, and imaging connecters. Creating an airtight component that fits into a modern computer or phone may seem like magic, but instead, it is something a hermetic company created.
