Amphenol Triax connectors are used in applications where maximum RF shielding and minimum noise radiation is required. Triax are engineered for superior performance, and are built to the highest quality standards.

They are the perfect solution for harsh environments with high temperatures. They can also be tested and approved for use in the nuclear reactor chambers.
