Hermetically Sealed Connectors: Advanced Solutions for Extreme Environments

Hermetically sealed connectors are essential components in applications where machinery and equipment are exposed to extreme conditions. From aerospace to medical industries, these specialized connectors ensure airtight protection, making them indispensable for sensitive electronic systems. Their robust design prevents the ingress of gases, moisture, and contaminants, safeguarding equipment functionality in harsh environments.

What Are Hermetically Sealed Connectors?

Hermetically sealed connectors are engineered to provide a secure, vacuum-tight seal between systems. They are commonly used in environments that experience extreme weather, fluctuating atmospheric pressure, and high altitudes. For instance, photographic and surveillance equipment on unmanned vehicles rely on hermetic seal products to maintain airtight integrity. These connectors are also critical in submarines and satellites, where they resist significant pressure differences while ensuring no moisture or gases compromise system performance.

Reliable Moisture and Gas Protection

One of the primary advantages of hermetic connectors is their ability to act as a robust barrier against moisture and gas penetration. When high-pressure differential barriers are necessary for electrical systems, poorly constructed seals can lead to malfunctions. Hermetically sealed connectors effectively mitigate these risks, providing long-term resistance to corrosion and ensuring system reliability. This is why industries like automotive, offshore drilling, and defense frequently use custom hermetic connectors tailored for their unique requirements.

Circular and Rectangular Connectors for Versatile Applications

Hermetically sealed connectors come in various configurations, including circular and rectangular designs, to accommodate different systems. Circular connectors are often preferred for their compact and durable build, making them ideal for aerospace and military applications. On the other hand, rectangular connectors offer versatility for larger-scale systems in manufacturing plants and laboratory equipment.

Applications of Hermetic Connectors

Hermetic connectors are used in a variety of applications where a high level of protection against environmental factors is required. Here are some common uses of hermetic connectors.

Vacuum and pressure systems

Hermetic connectors are used in vacuum and pressure systems, such as in the semiconductor industry, to create a seal that prevents air and other contaminants from entering the system.

Aerospace and defense

Hermetic connectors are used in aerospace and defense applications to protect electronics and other sensitive components from harsh environmental factors, such as high altitude, extreme temperatures, and electromagnetic interference.

Medical devices

Hermetic connectors are used in medical devices, such as pacemakers and hearing aids, to prevent bodily fluids and other contaminants from entering the device.

Oil and gas exploration

Hermetic connectors are used in the oil and gas industry to create a seal that prevents the ingress of harsh chemicals and other environmental factors.

Automotive applications

Hermetic connectors are used in automotive applications, such as airbag deployment systems, to protect electronics from heat, vibration, and other environmental factors.

Underwater applications

Hermetic connectors are used in underwater applications, such as submersibles and offshore oil rigs, to protect electronics from water and other corrosive substances.

Hermetic connectors are used in any application where protection against environmental factors is critical to the reliable operation of the system.

Selling Points for Lithium Battery Seals

Lithium battery seals employ the incredibly dynamic hermetic seal technology, which effectively makes the objects that are protected by them airtight. These seals can be applied to a large number of materials and are employed in a vast range of industries.

How Are Lithium Battery Seals Designed?

In the lithium battery design, the cells are all individually sealed and cannot leak. This benefits users because there is no restriction orientation of a lithium battery, which means that the battery can be installed upside down or on its side.

Hermetic connectors are a special class of sealed connectors that incorporate glass-to-metal or other highly-engineered sealing technology. Hermetic seal connectors are versatile and dynamic and are employed in a number of diverse applications, including submarines and satellites.

Whether you’re talking about hermetic seals and feedthroughs, battery seals, connectors or any other type of hermetic technology, this type of sealing is designed to ensure an absolute line of demarcation between the object and any other elements.

How Important Are Lithium Battery Seals?

Lithium battery seals prolong the life of your battery. Battery end seals also help to ensure that the battery doesn’t get too hot. The seals also prevent the emission of harmful gas and liquids.

What Hermetic Connectors Can Do?

Hermetic connectors provide airtight seals so that no air can enter or leave a container or space. In fact, the word “hermetic” is defined as airtight. When containers are pressurized or vacuum-sealed, they keep bacteria, moisture, and oxygen away and ensure that the interior of the space or container remains sterile.

Industries That Use Airtight Seals

There are many industries that require a high level of pressurized sealing, such as the offshore drilling, automotive, aerospace, and medical industries. Because every application is unique, there are customized options available in hermetic seals. For example, in a submarine or offshore oilrig, the hermetic connector would be suited for marine environments. A manufacturing plant would need a variety of types of seals, and these could be ordered to fit the proper specifications.

Types of Connectors

Hermetic seal connectors come in a variety of shapes and sizes, and they are made from different materials, such as titanium, stainless steel, aluminum, and bronze. They can be rectangular, circular, or a customized shape. Some are ceramic-to-metal, while others are glass-to-metal. Some of the finishing options are gold-plated, silver-plated, copper-plated, and bright tin-plated.

Whatever specifications are needed by an industry, hermetic connectors can be designed to fit the application. The proper design and material will result in the ability to withstand extreme temperatures and high pressure.

Making the Right Connections with Hermetic Connectors

Hermetic connectors are a fact of doing business in many industries. This ubiquity sometimes overshadows the engineering wonders that are made possible by these pieces of technology. They make many of the technological that we take for granted today possible. Here are a few of the more prominent examples from some leading industries.

Medical 

Medical science has come a long way in recent history. From heart transplants to MRI machines, things that past physicians only dreamed of are now commonplace. This is due in part to hermetic sealing technology designed for the medical industry. These connectors provide a pressure-resistant seal for various applications doctors and hospitals depend on. The unique glass, ceramic and metal construction provides the absolute best in failure resistance and durability. That’s important when lives are on the line.

Defense

This technology got its start in the military. With that in mind, it’s no surprise that most contemporary hermetic seal and connector manufacturers are well versed in Mil-Spec connections.
