SBMA Female RF Coaxial Connector (Right-Angle · Flange Mount · Compatible with #2 Semi-Flexible/Semi-Rigid Cables)
The SBMA connector is a low-power blind-mate RF coaxial connector, serving as the miniaturized upgraded version of the BMA series. Its core advantages lie in the combination of compact size and floating flange design—the former meets the strict space requirements of high-density assemblies, while the latter provides a flexible connection solution for modular integration of complex systems, especially suitable for scenarios requiring rapid deployment and maintenance.
Specifically designed for blind-mate connections in cabinets, chassis, and various high-density modular components. It efficiently handles environments with limited internal space and dense connection points, ensuring stable and reliable signal transmission between modules.
- Two-hole floating flange mount: Compensates for installation errors through the floating structure, enhancing connection stability and adapting to assembly requirements under different working conditions.
- Right-angle configuration: Optimizes wiring direction in confined spaces, reduces cable bending stress, and lowers the risk of signal loss.
- Broad cable compatibility: Supports connections with #2 semi-flexible and semi-rigid cables, balancing wiring flexibility and structural stability.
- Compact wideband design: Maintains wide frequency bandwidth performance in a small form factor, balancing space utilization and signal transmission quality.
- Floating connection mechanism: Enables quick alignment in limited spaces; even with slight installation deviations, it can still ensure reliable mating, significantly reducing the difficulty of blind-mate operations.
