Coaxial RF Seals – Hermetic Coaxial Connectors

Hermetic Coaxial Product Drawing Index
Hermetic Connectors Product Description Code
Coaxial, EMI Shielded

Versions available include BNC, SMA, SHV, MHV, N, and Triaxial with floating or grounded shields for pressure or vacuum uses. In addition, any type of coaxial or shielded cables can be hermetically sealed in almost any combination or length. Multi-pin coaxial PAVE-Mate connectors are also available for up to 29 shielded contacts.

Coaxial RF connector versions are available for up to 40 GHz or 100 GHz use. SMA Ka-band or 1.0mm types. Typical impedance control is ±10% of the nominal impedance value for the type connector selected unless a non-constant impedance connector type. Any special electrical requirements such as VSWR, insertion loss, RF leakage, TDR testing or tight impedance control should be first discussed with a PAVE sales engineer before ordering.
