FURUTECH FI-50 R - IEC connector

High-performance IEC connector in pure rhodium-plated copper. Stainless steel and carbon fibre housing. PiezoCeramic technology

Furutech's Pure Transmission FI-50 Piezo Ceramic series connector bodies and housings feature several technical innovations in construction. A multilayer non-magnetic stainless steel and carbon fibre housing incorporates a special damping and insulating acetal copolymer. Furutech opted for stainless steel and carbon fibre for the outer housing after extensive listening sessions with Japanese industry figures and audiophiles.
The connector body combines two 'active' materials: nano-sized ceramic particles and carbon powder. (Only the nanometre-sized ceramic particles couple effectively with the carbon powder). Nylon and glass fibre are also incorporated, forming an extremely effective, well-damped, mechanically and electrically non-resonant connector body. That's right, they are also electrically damped.
Piezoelectric effects are the key. Furutech's innovation in design and materials is based on the use of nanometer-sized polycrystalline ferroelectric ceramic particles that exhibit electrogenerative properties; mechanical pressure creates an electrical charge, forming a bridge between electrical and mechanical oscillation.
Carbon powder has thermally conductive characteristics that interact with the charged ferro-ceramic particles, converting their energy into heat that is conducted away and released from the surface of the connector body! These carefully selected and tested 'active' materials mechanically and electrically dampen the connector and socket while 'interconverting' thermal, mechanical and electrical energy for the best Furutech Pure Transmission signal imaginable.
