Vacuum feedthroughs

Vacuum feedthroughs

Electrical feedthroughs are components that are capable of conducting electricity through the wall of a sealed chamber. Feedthroughs consist of one or more electrical conductors that are insulated from a weldable metal housing. The dimensions, materials and design depend on the application requirements.

IPT's feedthroughs are manufactured using high-purity alumina ceramics as an insulating material and therefore, require a bonding technology which is generally called ceramic-to-metal sealing. These joints are helium tight and bakeable up to 350°C. This makes them ideal for use as instrumentation feedthroughs in HV and UHV applications as well as autoclaveable connectors for medical instruments.
