The PATC-1000 Series high-performance PEEK (PolyEtherEtherKetone) connectors are configurable with single or multiple high-density contacts. They have long-term creep and fatigue resistance over a broad temperature range, low flammability and smoke emission characteristics, and good electrical properties. These hermetically sealed connectors are helium leak tested to less than 10-8 sccm. They are suited for demanding applications as down hole tools, oil and gas well completion systems and aerospace and military applications.
