CeramTec North America LLC. - 15 Kilovolt (kV) Direct Current (DC) Voltage Rating, 7.5 Ampere (A) Conductor Current Rating, and 1 to 4 Pin Mini High Voltage (HV) Feedthroughs

Products

An assembly which provides for the transfer of electrical power, gases or fluids from outside a hermetic chamber to the inside. Feedthroughs can provide both a hermetic seal and electrical isolation from the chamber wall. Feedthroughs are sometimes referred to as 'pass-throughs'.
CeramTec feedthroughs provide the solutions for applications requiring hermeticity and electrical isolation.
