Key Features

1. Silver + Rhodium Plated Phosphor Bronze Contacts:

• High Conductivity Phosphor Bronze: The contacts of the C-037, P-037e, and C-237 are made from phosphor bronze, which offers a great balance between strength and conductivity. This ensures a stable and reliable power connection with minimal resistance.
• Silver + Rhodium Plating: The contacts are plated with a layer of pure silver, known for its excellent conductivity, followed by a layer of rhodium for enhanced durability and corrosion resistance. This combination results in optimal power transmission with a high level of detail and accuracy, ensuring that your audio equipment receives clean and stable power.

2. Precision Engineering and Solid Construction:

• One-Piece Body Structure: The connectors feature a solid, one-piece construction, reducing the potential for signal degradation and ensuring a robust, stable connection. This design minimizes vibration and provides consistent power delivery to your equipment.
• Secure and Tight Fit: The connectors are designed to provide a snug and secure connection, ensuring there are no loose contacts that could cause power fluctuations or interruptions. This is particularly important for maintaining sound quality in high-end audio systems.

3. Vibration Dampening and Resonance Control:

• POM Resin Housing: The outer housing of the C-037, P-037e, and C-237 is made from high-quality polyoxymethylene (POM) resin, which has excellent vibration-dampening properties. This helps reduce mechanical vibrations that can interfere with power transmission, ensuring a more stable and noise-free power supply.
• Enhanced Resonance Control: The design includes elements that control resonance effectively, further ensuring a clean and consistent power flow, which is essential for maintaining the integrity of the audio signal.

Comparison with Other Oyaide P/C Series Connectors

The C-037 / P-037e / C-237 connectors represent a reference-grade solution in Oyaide’s P/C series and offer unique advantages:

• Compared to C-004 / P-004e: The C-004 / P-004e features beryllium copper contacts with platinum + palladium plating, which offers slightly higher conductivity and durability. However, the C-037 / P-037e / C-237, with its silver + rhodium plating, provides a more balanced and detailed sound, making it ideal for those who prefer a more neutral and transparent audio experience.
• Compared to C-079 / P-079: The C-079 / P-079 connectors use brass contacts with gold plating, which offers warmth to the sound but is less conductive than the phosphor bronze and silver + rhodium combination of the C-037 / P-037e / C-237, making the latter a superior choice for those seeking greater accuracy and resolution.

The Oyaide C-037 / P-037e / C-237 connectors offer an excellent balance of conductivity, durability, and performance, making them the reference-grade choice in the P/C series. Their silver + rhodium plated phosphor bronze contacts, combined with precision engineering and vibration-dampening properties, provide clean and stable power delivery, which significantly enhances the sound quality of your audio equipment.

These connectors are an ideal choice for anyone looking to optimize their audio system’s power supply, whether in a high-end Hi-Fi setup, a professional studio, or a sophisticated home theater system. By investing in the Oyaide C-037 / P-037e / C-237, you can be confident that your audio equipment is receiving the purest and most reliable power, allowing you to experience your music and audio content with unparalleled clarity, accuracy, and depth.

Features

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.
