1、Pure copper (99.998% purity) as the insert, so that the electrical signal and current reach the light transmission rate, solving the signal distortion. 2、Exquisite electroplating process can improve conductivity and reduce magnetism and passed the CE/ROHS/PSE certification. 3、The first layer‑oxygen‑free copper, can improve conductivity. The second layer‑silver plating, greatly reduces the magnetic properties. 4、The third layer‑palladium plating, high hardness and wear resistance. The fourth layer is 24K gold‑plated, not easy to fade. 5、Treated with unique insulation and anti‑oxidation special process, which has a good shielding effect. 6、Nylon/glass fiber front body runs quietly‑better noise reduction effect can be achieved after installation. 7、The scope of application of this pure copper power plug connector can be all professional video appliances. 2 x Power Plug Item Type: Audio Power ConnectorPlug Specifications: The US Plug for Male Connector, and Universal for Female Connector Model: M105GConductor Material: 99.998% Pure CopperMain Body Material: Nylon/Glass Fiber (Bayer 2805)Connection: Hex ScrewApplicable Wire: Up to 4.5mm² (11 to 14 AWG)Installation Cable Diameter: 10mm-20mm/ 3.9- 7.9inRated Value: 15A 250V ACElectroplating Process: Oxygen-free Copper Plating/Silver Plating/Palladium Plating/24k Gold PlatingModel: F105GConductor Material: 99.998% Pure CopperMain Body Material: Nylon/Glass Fiber (bayer 2805)Connection: Positioning ScrewApplicable Wire: Up to 6mm² (11 to 14 AWG)Installation Cable Diameter: 10mm-20mm/ 3.9- 7.9inRated Value: 15A/125V 10A/250VElectroplating Process: Oxygen-free Copper Plating/Silver Plating/Palladium Plating/24k Gold PlatingScope of Application: Suitable for Professional Audio-visual Appliances
