Furutech FI-E50 NCF R

NCF Piezo Ceramic Series Connectors (A Furutech First)!

The connector bodies and housings in Furutech’s Pure Transmission Piezo Ceramic series feature several revolutionary construction techniques. A multilayer, silver-plated non-magnetic stainless steel and carbon fiber shell incorporates a special damping and insulating acetal copolymer. Furutech chose stainless steel and silver-plated carbon fiber for the outer housing after extensive listening sessions with Japanese industry figures and audiophiles.

Connector bodies incorporate “active” damping material

Incorporated into select Furutech products, the Nano Crystal² NCF formula is made up of a special crystalline material with two “active” properties. First, it generates negative ions that eliminate static electricity, and second, it converts thermal energy into far infrared. Furutech then combines this remarkable crystalline material with nano-sized ceramic particles and carbon powder for their additional damping properties via the “Piezo Effect”. The resulting Nano Crystal² formula is the ultimate electrical and mechanical damping material - found exclusively in Furutech products! The Nano Crystal² formula eliminates static, “interconverts” thermal, mechanical, and electrical energy, and damps vibration, all for the finest Furutech Pure Transmission signal imaginable.

Floating Magnetic Field Effects

How far will Furutech’s engineers go in their pursuit of Pure Transmission reference quality? Their focused examination of every element of signal transfer has resulted in another breakthrough technology, the Furutech Earth/Ground Jumper System. It eliminates electromagnetic interference (EMI) induced in metal parts like connector casing screws.

Current flowing through the power connector creates a magnetic field, just as an insulated conductor creates electromagnetic and electrostatic fields. Furutech’s engineers discovered that this magnetic field induced a current flow (and small magnetic field) in the screws holding the connector together! These magnetic fields interfere with the larger magnetic field around the conductor and connector.

Furutech’s total attention to detail and elegant engineering perfectly solves the problem. The Earth/Ground Jumper System connects the fixing screws to a ground terminal inside the plug, completely eliminating the field disturbances they cause. Stray fields are grounded via a series of locking parts inside the connector that attach to the ground conductor. The Jumper System is available in Furutech NEMA and IEC power connectors. The Earth/Ground Jumper System is covered under US Patent No. 6,669,491
