Hermetic Feedthroughs & Connectors
Precision-engineered electrical, RF, and optical feedthroughs for sealed systems in aerospace, medical, defense, and industrial applications.
Reliable Signal and Power Transmission Through Hermetic Boundaries
Advanced Hermetic Solutions designs and manufactures custom hermetic feedthroughs and connectors that transmit electrical, optical, or RF signals through sealed enclosures while maintaining vacuum, pressure, and contamination integrity. Our assemblies are designed for high-voltage isolation, low leak rate, and robust mechanical retention.
- Ceramic-to-metal and glass-to-metal configurations available
- High-voltage feedthroughs up to 20kV
- Multi-pin signal, power, and hybrid (optical/electrical) assemblies
- RF connectors with impedance-matched transitions
- Micro and nano connectors for miniaturized electronics
- Helium leak tested to < 1x10⁻⁹ atm·cc/sec
- Custom mounting flanges, threads, or weld rings
Our feedthroughs are optimized for mechanical stability, thermal expansion matching, and long-term field performance under temperature, pressure, or chemical stress.
Feedthrough Design Options
- Conductors: Copper, nickel, Kovar, gold-plated pins, platinum wires
- Insulators: 96% or 99.5% alumina ceramic, borosilicate glass
- Metals: Kovar®, Alloy 42, stainless steel, titanium
- Form factors: Threaded bulkhead, brazed-in flanges, circular or rectangular headers
- Sealing methods: Active brazing, glass sealing, compression sealing
- Connector interfaces: D-sub, SMA, MIL-spec, custom RF, micro-coax, fiber-optic
Applications Across Industries
- Aerospace: Engine sensors, telemetry, and propulsion feedthroughs
- Medical: Implantable electronics and sterilizable connectors
- Defense: Ruggedized enclosures, RF assemblies, and battlefield sensors
- Semiconductor: UHV chamber access, power supplies, optical isolation
