C-079 / P-079 / P-079e

The reference grade of P/C series with 24K gold plated phosphor bronze contacts


Every one of our products are totally "made in Japan" even down to minute component, all because for us to maintain our high standard of quality and reliability, it is essential to have every production system under our direct and strict control. Our products are for special market where minute vibration from loose connection or due to imperfect choice of material could become a vital failure.

We carefully design each and every component for easiness in assembling, simplicity and requirement, cost factor is secondary. Instead we ignore excess decoration and unnecessary complexity. We are proud to present the true value for your enjoyment.

These plugs and connectors are not merely high grade; every step is taken to realize the `State of the Art` for audio application.


Blade Features

■ Contacts
The basic material is 1.4mm thick deoxidized phosphor bronze 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 P-079/C-079 is 24k Gold.
Generally, 18k gold plating applied for industrial use is actually "gold alloy" due to enhancing its corrosion resistance property and durability. However, since we regard its sound quality as the most important priority factor, pure gold plating without nickel, cobalt and bismuth is selected for the plating of P-079/C-079.

Grade Purity (content rate)
14K 54.2-62.5%
18K 70.9-79.2%
20K 79.3-87.5%
22K 87.6-95.9%
24K 95.9% or more

Body Features

■ Inner Body
30% glass filled PBT has excellent machine-ability and provides superior electrical isolation. The highly rigid body of the P-037/C-037 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 high S/N ratio without being magnetized at its connection part.

■ Outer Housing
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.

Product Management System with Serial Numbered Hologram Seals

All Oyaide Electric's P/C series AC plugs and IEC connector are all labeled with a "hologram sticker" with a serial number for management purposes. The product is shipped in its original can case, which protects it from shocks during transportation.

It has been confirmed that counterfeit products that look very similar to the "P/C series AC plug and IEC connector are currently circulating.

All products are shipped in an "original can case," with a "hologram sticker" with serial number attached to the side of the main body, and the name sticker attached to the side of the main body has been changed to an "aluminum plate sticker" to distinguish it from counterfeit products.

Before your purchasing, please contact your local authorized Oyaide distributor if you are unsure.
