The Oyaide 037 Series Mains Connectors (available as the C-037 IEC connector, P-037 US/UL plug, and P-037e Schuko plug) are precision-engineered audiophile power terminals manufactured in Japan. Designed as a high-performance upgrade over standard brass connectors, the 037 series features deoxidized phosphor bronze contacts coated with a two-layer plating of pure silver (1.5 µm) and rhodium (0.3 µm) to achieve exceptional electrical conductivity, minimal contact resistance, and long-term corrosion resistance.

Housed in a high-rigidity 30% glass-filled PBT body encased in a durable, translucent blue polycarbonate outer cover, these connectors effectively damp micro-vibrations and electromagnetic interference. Non-magnetic stainless steel hardware ensures high clamping force without introducing parasitic magnetic distortion.

KEY FEATURES & PROPRIETARY TECHNOLOGIES

• Dual-Layer Silver & Rhodium Plating: Features a 1.5 µm pure silver base layer for high-speed signal conductivity, topped with a 0.3 µm rhodium outer layer for surface durability, tarnish prevention, and extended contact life.
• Deoxidized Phosphor Bronze Contacts: 1.4 mm thick precision-polished phosphor bronze contact blades ensure strong mechanical spring tension and high current capability.
• Vibration-Damping PBT Body: Structural core made from 30% glass-fiber reinforced PBT (Polybutylene Terephthalate) for structural rigidity, thermal stability, and mechanical resonance control.
• High-Rigidity Polycarbonate Shell: Translucent blue polycarbonate outer casing provides high impact resistance while further damping internal vibration frequencies.
• Non-Magnetic Stainless Steel Screws: Custom-machined non-magnetic stainless steel terminal screws permit high fastening torque without stripping threads or inducing magnetic hysteresis distortion.
• Heavy-Duty Cable Strain Relief: Internal clamping system securely holds thick audiophile power cables up to 17.0 mm in outer diameter with over 30 kg of pulling force tolerance.
