Multiple Connectors

Ceramic-to-Metal and Glass-Ceramic-to-Metal multipin connectors are feedthroughs with two or more conductors. They are made for accepting plugs on the air side, and some feedthroughs allow for plugs on the vacuum side.
Hermetic multipin feedthroughs are used primarily to provide instrumentation signals, voltage and/or current into a high-vacuum or ultra-high vacuum environment, with an in-line connection to outside instrumentation.

ceramic for Pressure transducers

Ceramic to metal Multipin Connector Application:

  • Semiconductor processing equipment
  • Analytical test and measurement equipment
  • Pressure transducers
  • Power generation (measurement and control technology)
  • Particle accelerators
  • Furnaces
  • Energy research

All receptacles are made from high-purity, vacuum compatible materials. The insulators are made from high-strength, low-loss alumina ceramics that are metalized using the refractory-metal sintering process. Metals include Kovar®, stainless steel, nickel-iron alloys, cupro-nickel alloys, molybdenum, and Alumel®. The assemblies are brazed together using copper, gold-copper, or silver-copper alloys.
