Shell Design

The connector’s outer shell is carefully designed to provide mechanical protection and a secure connection. This includes various considerations — such as the shell’s shape, size, and material — and features like locking mechanisms or threaded fittings. The goal is to ensure the connector remains firmly connected, even under intense vibration, shock, or thermal expansion conditions.

Shielding

Many hermetic connectors incorporate shielding to protect against electromagnetic interference (EMI). This is essential in environments where electronic noise can disrupt signal integrity, such as in military communications or sensitive medical equipment.

Environmental Considerations

Hermetically sealed connectors are often deployed in environments characterized by extreme temperatures, pressure, humidity, or exposure to corrosive substances. As such, the design must consider these environmental factors and incorporate features to withstand such conditions without compromising performance.

Key Manufacturing Processes

Manufacturing hermetically sealed connectors involves several meticulous processes to ensure each connector meets stringent quality standards. These include the following:

Machining

Advanced techniques such as computer numerical control (CNC) machining are employed to create metal and ceramic components with tight tolerances and intricate designs. This ensures that each component meets the specifications for perfect fit and optimal performance.
