About the 7-16 Interface

The 7-16 series is a highly ruggedized, threaded interface design for high power/voltage applications. The 7-16 designation refers to the ratio of the inner and outer conductors and is governed by the IEC standard 169-4 DIN 47223. Two interface configurations are commonly employed; a slotted outer spring finger design or a solid wall version depending upon performance requirements. This series is commonly used in commercial applications requiring high voltage capacity and often sensitive passive intermodulation performance (PIM) in excess of – 155 dBc. 7-16 connectors are often specified with non-magnetic tri-metal plating (TRUlustre™) in such PIM sensitive communication applications.
