Product QM FX Series Metal Push Pull Connectors are classic self-locking circular connectors designed for high-speed signal transmission in military, aerospace, medical, test and measurement, communication and industrial control applications. The series supports multiple connection types, including DC, AC, high-speed signal, RF and optical connections, making it suitable for precision systems that require stable transmission in compact equipment layouts.
The FX series is especially useful for high-density installations and applications where rotational mating is difficult. With a push-pull self-locking structure, the connector can be mated and unmated quickly without requiring rotational operation, helping improve assembly efficiency and usability in narrow or panel-mounted spaces.
With stable panel mounting, IP68 waterproof protection, ultra-low leakage hermeticity, excellent shielding performance and a reversible pin-and-socket design, QM FX series connectors provide reliable connection performance under vibration, humidity, salt spray and wide temperature conditions. The series is suitable for equipment that requires high-speed transmission, compact installation and long-term signal stability in demanding environments.
