Materials ■ Contacts The basic material is deoxidized phosphor bronze (1.4mm thick) for strength and secure contact. When connected, they can take over 7kg load. Surface is thoroughly polished twice. ■ Plating The manufacturing process is started from foundation coating. The material which was punched out as a part is polished by hand piece by piece after machined barrel-polishing. The plating of the seires are: C-037 - a combination of silver (1.5micron) and rhodium (0.3 micron). C-046 - a combination of 24k gold (1.5micron) and palladium (0.3 micron). C-079 - 24k gold （2.0μ) Body ■ Body 30% glass filled PBT has excellent machine-ability and provides superior electrical isolation. The highly rigid body effectively attenuates high-speed vibrations. All screws, which were originally designed for P/C series, are made of highly rigid stainless steel which is non-magnetic substance. Moreover, the cable cannot be separated from the plug by a force less than 30kg, a significant safety feature. ■ Stainless screws The screws of P/C series are all made of highly rigid stainless so its screw head doesn't collapse even if you give them too much strength. In addition, because it is non-magnetic material, it helps to achieve hign S/N ratio without being magnetized at its conection part. ■ Outer cover The outer cover of P/C series is made of PC(PolyCarbonate) for its rigidity and hardness. It helps to attenuate tiny vibrations in quick response and reduce distortions by its superior mechanical strength.
