7/16
7/16

The 7/16 series name derives from the metric dimensions of the connector interface: 7mm OD of inner contact, 16 mm ID of outer contact. 7/16 connectors are designed for use in communications systems with power levels of 100 watts per channel. Popular in Europe for a long time, the 7/16 interface has gained acceptance in the U.S. for its ability to operate at elevated power levels.

Deutsh Industries Norm (DIN) is an acronym for German standards that apply to 7/16 connectors and are gaining acceptance worldwide. There are three families of 7/16 DIN connectors: corrugated cable (both Annular and Superflex), standard cable connectors and custom.

RF coaxial connectors are the most important element in the cable system. Corrugated copper coaxial cables have the potential to deliver all the performance your system requires, but they are often limited by the performance of the connectors. Corrugated connectors have been designed from the ground up to deliver optimum performance, while retaining ease of installation. Inter-modulation distortion, a major concern in today's communications systems, is consistently low with these connectors. Typical performance is -125 dBm (-168 dBc).
