P-037 / C-037 / P-037e

The reference grade of P/C series with silver + rhodium 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 is1.4mm 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-037/C-037 is a combination of silver and rhodium which were selected as a result of repeated listening tests. The inner silver layer is 1.5 microns thick and the outer rhodium layer is 0.3 microns thick.

Contact point capable of withstanding a pulling load of 30 kg
The tensile strength of the blade holder and cable is more than 30 kg, and even a slight pull will not cause the cable to come loose. This is also the result of careful consideration of safety.

No-compromise parts selection, not only just blade parts

■ Non-magnetic stainless steel screws
Oyaide's commitment to its products starts with a single screw. The screws used in the P/C series are custom-made stainless steel screws made for the P/C series, which are non-magnetic and, of course, have a narrower screw pitch to increase the contact area between the body and the cover.

As a result, the body and cover are not easily distorted, and the screws do not loosen easily.

Have you ever experienced over-torquing and having the threads crushed? All the screws used in our plugs are made of stainless steel, so there is no possibility of the screw threads being crushed or the heads being removed even if excessive torque is applied. In addition, stainless steel itself is non-magnetic, so there is no shivering at the connector, providing a high S/N sound.

■ GF+PBT 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

■ High rigidity polycarbonate 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.

■ Handling maximum cable outer diameter
Have you ever used butyl or noise-isolating tape for vibration control when making your own power cables, only to end up with thicker cables?

This product can accommodate cables with a maximum outer diameter of 17mm for both IEC plugs and power plugs, so that even such customers can use this product with peace of mind. Now you don't have to worry even if your cables have become thicker by using tapes or vibration-damping treatments.

*When the clamper is removed, cables up to 17mm O/D can be installed.

■ Handling maximum Wire Size
You want to use and make as thick a cable as possible! For such customers, we can accommodate cable installation sizes up to 10sq (5.5sq x 2 cables) (however, the allowable current is 125V 15A).

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.
