Description
This connector is engineered for maximum mechanical and electrical stability. The 4-hole square flange allows for secure mounting to equipment enclosures, preventing any rotational stress on internal solder joints when mating heavy-duty 7/16 DIN plugs. The SM 250 cable is soldered directly to the center contact and outer body, creating a gas-tight bond that eliminates the micro-gaps responsible for signal distortion.
The body is typically finished with tri-alloy (white bronze) plating, providing superior conductivity and resistance to environmental oxidation compared to standard nickel. Internal PTFE (Teflon) insulation ensures high voltage handling and thermal stability, allowing the connector to manage hundreds of watts of continuous RF power while maintaining clean signal transmission in multi-carrier 5G environments.
Key Technical Advantages
-
Mechanical Stability: The 4-hole square flange provides a rock-solid mechanical ground and prevents the connector from loosening under high installation torque (up to 30 Nm).
-
Low PIM Engineering: Constructed with non-magnetic materials to achieve ultra-low PIM (typically ≤ -160 dBc), protecting receiver sensitivity.
-
Broadband Precision: Fully optimized for frequencies from DC to 7.5 GHz, covering all major sub-6GHz 5G and satellite communication bands.
-
SM 250 Optimized: The internal dimensions and solder cup are precision-matched to SM 250 cable, ensuring minimal return loss and high power handling.
-
Durable Construction: Built for longevity in harsh environments, maintaining its electrical specifications over hundreds of mating cycles.
