The 7-16 series (DIN) are widely used coaxial connectors in the mobile communications sector. These robust connectors feature a screw-lock mechanism and are waterproof. Depending on the design, they can be used at frequencies of up to 7.5 GHz. The 7-16 connectors have a characteristic impedance of 50 Ω. Connector variants are available for flexible, semi-flexible, semi-rigid, and corrugated cables. Cables can be connected via soldering, crimping, or clamping. These connectors are primarily used in mobile communications. Additionally, they are also utilized 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.
