All of these products are built to endure extreme conditions, whether it be an ultra-high vacuum (UHV) environment, temperatures ranging from cryogenic (4K) to 450 degree C, pressures in excess of 25,000 psig, corrosive or caustic environments, while maintaining an unsurpassed level of reliability and performance.
Testing & Inspection
CeramTec feedthroughs provide the solutions for applications requiring hermeticity and electrical isolation. In addition to remaining leak-free in high and ultra-high vacuum, many of Ceramaseal® feedthroughs can accommodate: • High temperatures • Cryogenic temperatures • High pressure • Aggressive chemicals
CeramTec 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 too. Product variations include Sub D (MIL-C-24308) type and circular connector types MIL-C-26482 and MIL-C-5015.
CeramTec coaxial connectors consist of two concentric conductors: a central conductor surrounded by and insulated from a second tubular conductor. The outside conductor is usually at ground potential but in some product variations may be floated off ground by employing an additional insulating ring. The outer conducting surface can prevent radio frequency noise from passing to or from the central conductor.
CeramTec electrical isolators, sometimes referred to as ‘breaks’ or ‘envelopes’ consist of metal sleeves brazed to each end of an insulating ceramic tube. These assemblies provide electrical isolation of system components that operate within a common environment. They can also be used to act as a conduit to introduce gases or liquids into hermetic systems.
CeramTec pressure feedthroughs are terminated in NPT (National Pipe Thread) fittings or other threaded fittings to allow for easy bulkhead installation. The NPT pressure units are designed to be sealed using Teflon tape or other acceptable sealants. All other designs use an o-ring seal.
