Thanks to their excellent resistance to electromagnetic interference, as well as their waterproof, dustproof, and locking features that prevent disconnection, metal-shielded circular connectors are widely used in base station equipment, outdoor communication terminals, vehicle-mounted communication devices, industrial switches, and private network communication devices. They support power supply, high-speed signal transmission, and RF data transmission, and are designed to withstand harsh outdoor environments—including extreme temperatures, rain, and dust—ensuring continuous and stable communication links with no signal attenuation.
