The 7-16 series (DIN) are widely used coaxial connectors in the mobile communications sector. These rugged connectors feature a screw closure and are waterproof. Depending on the version, they can be used at frequencies of up to 7.5 GHz. The connectors of the 7-16 series have a characteristic impedance of 50 Ω. Connector variants are available for flexible, semi-flexible, semi-rigid, and corrugated cables. Cables can be connected by soldering, crimping, or clamping. These connectors are particularly used in mobile communications. Additionally, they are also employed for testing purposes where resistance to vibration and weather is required. The special design of the 7-16 connectors ensures excellent performance in terms of return loss (VSWR) and intermodulation resistance. 7-16 connectors are suitable for transmitting high power at high frequencies.
