1、Using pure copper (red copper 99.998% purity) as the insert, the electrical signal and current can realize the speed of light transmission rate. 2、The face is treated with unique insulation, anti‑oxidation, and wear‑resistant special process, which has a good shielding effect. 3、Nylon/glass fiber front body runs quietly‑higher noise reduction effect can be achieved after installation. 4、The first layer of oxygen‑free copper can improve conductivity. The second layer‑silver plating, greatly reduces the magnetic properties. 5、The third layer‑palladium plating, high hardness and wear resistance. The fourth layer‑rhodium‑plated, corrosion‑resistant, strong and wear‑resistant. 6、This power connector is suitable for professional audio‑visual appliances and with CE/ROHS/PSE certification. 1 x Power Plug Item Type: Audio Power ConnectorPlug Specifications: The Male Connector is US Plug; the Female Connector is UniversalModel: M100R Conductor Material: Pure CopperMain Body Material: Nylon/Glass Fiber (Bayer 2805)Connection Method: Hex ScrewInstallation Wire Diameter: Maximum 4.5mm² (11AWG to 14AWG )Installation Cable Diameter: Approx. 6mm-18mmRated Value: 15A 250V ACElectroplating Process: Oxygen-Free Copper Plating/Silver Plating/Palladium Plating/Rhodium PlatingModel: F100RConductor Material: Pure CopperMain Body Material: Nylon/Glass FiberConnection Method: Set ScrewInstallation Wire Diameter: Maximum 6mm² (10AWG to 14AWG )Installation Cable Diameter: Approx. 6mm-18mmRated Value: 15A/125V 10A/250VElectroplating Process: Oxygen-Free Copper Plating/Silver Plating/Palladium Plating/Rhodium PlatingCompatibility: For Professional Audio-Visual Appliances
