The **P-06-R** refers to a high-end audio power connector (specifically an AC power plug) manufactured by the Japanese company **Oyaide Electric**. This component is widely used in the audiophile industry for DIY power cables and high-fidelity audio systems. --- ### 1. Key Technical Specifications The "R" in P-06-R stands for the specific plating used on the contact points, which defines its electrical characteristics. | Feature | Specification | | :--- | :--- | | **Model Type** | AC Power Plug (NEMA 5-15P Standard) | | **Blade Material** | Deoxidized Phosphor Bronze | | **Plating** | Palladium over Platinum | | **Housing Material** | High-density PBT with 30% Glass Filler | | **Outer Shell** | Polycarbonate | | **Voltage/Amperage** | 125V / 15A (E marked) | | **Max Cable Diameter** | 17.0 mm | --- ### 2. Core Electronic Components & Materials #### A. Contact Blades (Phosphor Bronze) The base metal is **Deoxidized Phosphor Bronze**. In electronics, this material is chosen over standard brass because of its superior spring properties, higher fatigue resistance, and better electrical conductivity. It ensures a high-pressure connection against the wall outlet. #### B. The Dual-Plating System The P-06-R is famous for its specific "layering" of precious metals: 1. **Platinum Layer (0.5 microns):** Applied directly over the polished bronze to provide a hard, durable base. 2. **Palladium Layer (0.3 microns):** Applied as the outer layer. Palladium is highly resistant to corrosion and oxidation, ensuring the electrical contact remains "clean" over years of use without the need for chemical cleaners. #### C. Body and Insulation The internal body is made of **Polycarbonate and PBT (Polybutylene Terephthalate)**. These materials provide high dielectric strength (insulation) and mechanical rigidity to dampen vibrations, which is a key requirement in high-end audio to prevent microphonics. --- ### 3. Electrical Performance Characteristics * **Low Contact Resistance:** The hand-polishing of the blades before plating increases the surface area contact, reducing resistance. * **EMI/RFI Shielding:** While the plug itself isn't a filter, the high-density housing helps shield the internal terminations from external electromagnetic interference. * **Sound Profile:** In the audio community, the Platinum/Palladium combination is known for a "fast," detailed, and neutral sound compared to the "warmth" of Gold plating (found in the P-06-G model). --- ### 4. Connection Interface The P-06-R uses a **Screw Terminal** system for wire attachment. * **Compatibility:** It can accept wire gauges up to 10 AWG (approximately 5.5 sq mm). * **Torque:** The stainless steel screws allow for high-torque tightening, ensuring a gas-tight mechanical connection to the copper conductors of the power cable.
