Furutech FI-50R - High End Performance IEC Connector The Furutech FI-50R IEC connector delivers exceptional audio performance through advanced materials and innovative design, ensuring pure signal transmission with minimal vibration and distortion. Key Features Piezo Ceramic Series connector bodies with nano-sized ceramic particles and powdered carbon for superior damping Multilayer nonmagnetic stainless steel and carbon fibre housing with acetal copolymer for enhanced insulation and vibration absorption α (Alpha) Pure Copper Rhodium-plated conductor for optimal conductivity Earth (Ground) Jumper System (US Patent No.: 6,669,491) for improved grounding Mechanically and electrically non-resonant connector body incorporating nylon and fibreglass Metal cable clamp reduces mechanically and electrically induced distortion Specified for cable diameters from 6mm to 20mm Specifications Body length: 44mm Diameter: 40.5mm Overall length: 80.3mm Product Description The Furutech FI-50R features a groundbreaking Pure Transmission design using Piezo Ceramic Series connector bodies and housings. Its multilayer shell combines nonmagnetic stainless steel and carbon fibre with a special damping and insulating acetal copolymer, chosen after extensive listening sessions with Japanese industry experts and audiophiles. The connector body integrates nano-sized ceramic particles and powdered carbon, materials that work together to mechanically and electrically damp vibrations and resonance. Nylon and fibreglass further enhance the connector’s stability, making it both mechanically and electrically non-resonant. Piezoelectric effects are harnessed through nano-sized polycrystalline ferroelectric ceramic particles that generate electrical charges under mechanical pressure, bridging electrical and mechanical oscillations. Carbon powder’s thermal conductivity converts this energy into heat, which is safely dissipated from the connector body’s surface. These advanced materials and design innovations ensure the FI-50R delivers the finest Furutech Pure Transmission signal quality, improving frequency extension and tonal clarity for high-end audio applications.
