What are Hermetic Connectors?
Hermetic connectors are specialized interconnect devices that use glass-to-metal or ceramic-to-metal sealing techniques to provide airtight and moisture-resistant connections. These connectors are engineered to withstand extreme pressure, temperature fluctuations, and corrosive conditions.
Key benefits include:
- Protection against gas and fluid leakage
- Long-term reliability in extreme conditions
- High electrical insulation and mechanical strength
- Durability in vibration- and shock-prone environments
They are widely used in aerospace systems, submarines, military equipment, and medical implants where performance cannot be compromised.
