What Are Hermetic Headers?

Hermetic headers are essential components for protecting electronics from moisture, gases, and extreme environmental conditions. They provide airtight sealing for applications that require resistance to temperature, vacuum, corrosion, and pressure variations.

Types of Hermetic Headers

Complete Hermetics manufactures a full range of hermetic headers, including:

• Multi-pin hermetic headers – used for systems requiring multiple electrical pathways.
• Single-pin hermetic headers – ideal for simple, compact, and high-reliability applications.
• TO hermetic headers – widely used in optoelectronics, sensors, and semiconductor packaging.

Each header is engineered with precision to deliver maximum reliability across industries such as aerospace, defense, automotive, and medical devices.

In mission-critical industries where failure is not an option, hermetic headers play a pivotal role in ensuring the performance and longevity of sensitive electronic systems. From aerospace to medical devices, these components are engineered to create airtight seals that block out moisture, gas, and pressure variations—guaranteeing reliability even in the harshest operating environments.

Engineered with Glass-to-Metal and Ceramic-to-Metal Seals

At the core of every high-performance hermetic header lies advanced sealing technology. Glass-to-metal and ceramic-to-metal seals offer superior electrical insulation, mechanical strength, and environmental resistance. Whether embedded in a satellite module, surgical implant, or defense sensor, these headers maintain internal integrity when exposed to extreme temperature swings, corrosive elements, or high altitudes.

Custom Multi-Pin and TO Headers for Complex Assemblies

When high-density signal or power transmission is required across sealed barriers, multi-pin hermetic headers provide the optimal solution. These are critical in advanced systems such as pacemakers, avionics, and communication devices. For high-frequency or optoelectronic uses, TO headers (Transistor Outline headers) are designed to support TOSA/ROSA modules, delivering precision connectivity while managing thermal constraints.

Hermetic Connectors and Feedthroughs for Ultimate Reliability

In underwater, vacuum, or space applications, hermetic connectors and feedthroughs act as the protective bridge between sealed environments and critical electronics. Available in both standard and custom configurations, they provide long-term seal integrity and ensure continuous operation across demanding industrial and scientific settings.

Experience unmatched reliability, precision, and protection with Complete Hermetics—engineered for excellence.

 

In environments where failure is not an option—such as aerospace, medical, and defense systems—hermetic products play a crucial role in protecting sensitive electronics. Among them, hermetic headers stand out for their unmatched ability to shield internal components from moisture, corrosive gases, extreme temperatures, and pressure fluctuations. Trusted across mission-critical applications, these components are the silent protectors of performance and safety.

Precision-Engineered Hermetic Headers

At the heart of many electronic assemblies lies the glass to metal seal or ceramic to metal seal, ensuring airtight integrity. These technologies, central to the design of hermetic headers, prevent environmental ingress while supporting high electrical insulation and mechanical strength. From satellite modules to surgical implants, these headers maintain operational stability under the harshest conditions.

Multi Pin Headers: Designed for Demanding Interfaces

Custom hermetic feedthroughs like multi pin headers offer seamless signal transfer between sealed environments. These components are key for data, power, and signal continuity while preserving the integrity of the system. In scenarios where life or mission success depends on reliability, such as avionics or pacemakers, these headers are indispensable.

TO Headers for Optoelectronic Precision

TO headers, or Transistor Outline headers, are optimized for optical and high-frequency applications. Often integrated into TOSA and ROSA assemblies, they enable superior performance in communication systems. Every TO header from Complete Hermetics is carefully tailored to meet your exact specifications—ensuring reliability in both space-limited and heat-sensitive environments.

Hermetic Connectors: Dependable Sealing for Complex Systems

Whether used in subsea installations or vacuum chambers, hermetic connectors provide robust sealed interfaces between different electronic units. These connectors, available in standard or custom hermetic feedthroughs, protect against system failure by maintaining perfect seals under dynamic pressure and thermal stress.
