The N-coaxial connectors were named after their inventor Paul Neill, who developed this standard for RF connectors in 1942. Often, however, the name also relates to the Navy Connector. Type N connectors can be used at frequencies up to 11 GHz, high-precision types up to 18 GHz. It is typically used in mobile communication applications with demanding mechanical and electrical requirements. SPINNER exclusively manufactures connectors with non-slotted outer conductor contacts and a special sealing profile in the connector head instead of the flat seal disk, specified by IEC or CECC. This ensures the most reliable sealing function.
