The pins are gold-plated brass, and the lead wires are 5N pure silver which are insulated with a double layered silk covering. The rhodium plated lead tip is made of phosphor bronze.
5N Silver lead wires （HSR-AG）
0.2mm 5N pure silver wires are manufactured by advanced manufacturing processes such as continuous casting process in high-frequency electric furnace, cold rolling process, annealing operation and drawing process. They are stranded in seven lines to insure enough cross-sectional area and minimize its conductor resistance.
The employment of double layered silk covering insulator realizes clean signal transmission without static electrical charge. Although resinic materials such as PVC or FEP are easy to be negatively charged, in contrast, silk has electric resistivity to static charge and excellent electrical characteristic. Moreover, the glass fiber sleeve also has high insulation property and resistance to electrical static charge.
The rhodium plated lead tip is made of phosphor bronze and enhances degree of adhesion with contact pins.
