MIL-SPEC Hermetic Connectors

Applications of Hermetic Connectors

Posted by admin on

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.

Protecting Contents From Infiltration

Hermetic connectors like those we make are used in settings where contents must be completely sealed off from invasion. Protect objects and container contents from contaminants such as:

  • Bacteria
  • Moisture
  • Oxygen

Airtight seals, containers, and feedthroughs are essential to many different concerns, including off-shore drilling, aerospace engineering, submarine design and construction, military aircraft development, manufacturing plant operation, and much more. We are pleased to provide solutions that conform with the highest industry standards; you can feel confident that our components are going to perform reliably in all standard use scenarios.

Best Manufacturing Practices

Hermetic connectors, seals, and other components are made using all best practices for manufacturing and fabrication. Glass-to-metal feedthroughs are made with a wetted seal that bonds tightly; connectors are tested to 100% hermeticity.

What Can a Hermetically Sealed Connector Handle?

Posted by Kaylyn on

A hermetically sealed connector is designed to deal with extreme conditions. That is the reason it is often used for military or industrial purposes. Astronauts and scuba divers may rely on these connectors to provide the best possible connection in the most unlikely places. Lives may literally depend on the strength of a seal, so that is why it is essential to choose the right connector.

Types of Hermetic Connectors

The kind of hermetically sealed connector you choose most likely depends on how secure you need the connection to be and whether you want a custom connector. A popular kind is a glass to metal connector that is made out of molten glass and is combined with metals. Ceramic to metal types are also available, and they require more time to produce, but can be custom-designed. Whatever material you select, the connector should provide the strong connection you need for any job.

Under What Conditions Can Hermetic Connectors Hold Up?

A hermetically sealed connector can hold up to extreme temperatures and below zero conditions. They should be able to withstand conditions in a spaceship and zero gravity or areas of high pressure. The connectors can also work in a vacuum and at the bottom of the sea. Simply put, hermetic connectors can handle just about anything.

Hermetic Sealed Connectors: Customization Considerations

Posted by Kaylyn on

Hermetic sealed connectors are important in regards to system integrity maintenance. These connectors may be used in aerospace operations or military. They may be used in gas-tight barriers and may have to withstand extreme pressures. It’s important that you can optimize your connectors to match your requirements.

Environmental Factors 

To customize hermetics, you must consider harsh or hostile environments. Will your hermetic connectors be exposed to vibration, shock or thermal changes? You have to factor the environment and conditions into the design. You may also need to choose between different plating requirements. You can choose from tin, nickel and both hard and soft golds. 

Testing Required

In the planning stages of the design, testing requirements are considered. These aspects are discussed at length and most qualification tests can be performed during assembly. The types of testing that hermetic sealed connectors may have to undergo include:

  • Pressure testing
  • Leak testing
  • Geometrical testing
  • Electrical testing
  • Insulation resistance
  • Voltage

In addition to testing, quality seals are inspected thoroughly.

To design hermetic connectors, there are ranges of materials that may be used in the process. From glass to metal seals and advanced sealing techniques, there are options for a variety of connectors. When receiving custom connectors, it is crucial that you address all of your different requirements.
