These lightweight, shielded circular connectors are compact, shock-resistant, and capable of withstanding extreme temperatures; they are also waterproof and tamper-resistant. They are commonly used in drone flight control systems, power motors, aerial photography cameras, obstacle-avoidance sensors, video transmission modules, and battery interconnections. They reliably transmit power, high-definition video, and control signals, withstanding the vibrations of high-speed flight and outdoor conditions such as rain and snow, ensuring stable and reliable flight control and aerial data transmission.
