Coaxial, EMI Shielded
MOST PAVE HERMETIC SEALS ARE BI-DIRECTIONAL SEALS FOR VACUUM OR PRESSURE.
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 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.

Seal Integrity PAVE-Seal® PAVE-Mate®
While all PAVE products will comply with helium leak rating from <10-6 cc/sec to 10-9 cc/sec (air equivalent) depending upon design, PAVE also uses more cost effective air bubble in fluid leak testing typically at 80 psi (5 bar). Special high pressure testing up to 10 k psi (600 bar) is also available.
