Products

CeramTec's multipin connector category of products describes hermetic feedthroughs of two or more conducting pins that accept plugs on the air side. Some connectors allow for plugs on the vacuum side as well.
Product variations include instrumentation Sub D (MIL-C-24308) type and circular connector types MIL-C-26482 and MIL-C-5015.

Applications N/A A few of the many applications in which these multipin connectors are commonly used are:
  • Semiconductor processing equipment
  • Analytical test and measurement equipment
  • Pressure transducers
  • Power generation: Measurement and control
  • Particle accelerators
  • Furnaces
  • Energy research
  • Commercial and military aircraft
  • Aerospace
  • Telecommunications
  • Oil Exploration
  • R&D
  • High Energy Physics
  • Biotechnology
  • Ceramic-to-Metal
Additional Information N/A The products in this section are used primarily to provide instrumentation signals, voltage and/or current into an ultra-high vacuum environment, high pressure, or many other extreme environments, with an inline connection to outside instrumentation. Designs adapt a Ceramaseal® feedthrough (receptacle) with an industry-standard plug.

The connector assembly is characterized by the Mil Spec designation, installation method and number of pins. In situations where voltage and current requirements are moderate, CeramTec is able to achieve a very high pin density using glass ceramic technology. CeramTec's designs include both single-ended and double-ended connector assemblies.

In-Vacuum Ribbon Cable

CeramTec's in-vacuum ribbon cable is designed to complement our Sub D Type (MIL-C-24308) hermetic multipin connector product line and therefore cable configurations include 9, 15, or 25 conductor cable. Note that 50 conductor cables are created by using two 25 conductor cables. Each of the Kapton® wrapped (19 x 0.0063) 22 AWG silver plated copper conductors are woven with a PEEK (polyether ether ketone) monofilament in order to achieve the ribbon cable form. The multistranded wrapped cable offers the most flexible solution and has a temperature range up to 200 ºC. All ribbon cable assembly Materials are ultra-high vacuum (UHV) compatible. The ribbon cables are vacuum baked out prior to shipping. Additional vacuum bake out prior to use is also recommended. All cable assembly components are sold separately.
