2. X Series Connector description:
- High-Speed Capabilities: Supports direct transmission of high-speed signals for various standard protocols (USB2.0, USB3.0, Gigabit Ethernet, 10 Gigabit Ethernet, HDMI, SATA, DP, etc.).
- Single Connector: Integrates the transmission of multiple signals including low-frequency, power, high-speed, RF, and optical fiber through a single connector.
- Straight Push-Pull Locking Structure for Plugs and Sockets: Enables blind mating and allows for quick connections and disconnections.
- Nut-Fastened Socket Installation: Equipped with a conductive O-ring, providing shielding and sealing functions.
- Multi-Key Positioning: dual error-prevention methods with aliginment key structure error-proofing and visual color cues to prevent incorrect insertion.
- Socket Leakage Rate: With a pressure differential of 1×10^5 Pa, the leakage rate should be less than 1.0 Pa·cm³/s (excluding optical fiber and RF products).
- Water Pressure Resistance: After mating, the plug and socket can withstand water pressure at a depth of 2 meters for 24 hours (excluding optical fiber and RF products).
- Pin and Socket Compatibility: Both plugs and sockets can be fitted with either pins or sockets (excluding optical fiber and RF products).
- High-Speed and Low-Frequency Electrical Contacts Termination: Plugs use wire soldering, and sockets are available in wire soldering and straight PCB soldering types.
