Furutech F! 50 NCF (R) IEC
NCF Piezo Ceramic Series Connectors • A Furutech First!
Furutech’s Pure Transmission FI-50 NCF Piezo Ceramic series connector
bodies and housings feature several breakthrough construction
A multilayer nonmagnetic stainless steel and silver plated carbon fiber
shell incorporates a special damping and insulating acetal copolymer.
Furutech settled on stainless and silver plated carbon fiber for the
outer housing after extensive listening sessions with Japanese industry
figures and audiophiles.
The body of the connectors incorporates an "active” damping material:
Nano Crystal² Formula - Nano Crystalline, Ceramic and Carbon Powder
Incorporated into select Furutech products, Nano Crystal² Formula ---
NCF is comprised of a special crystalline material that has two "active”
properties. First, it generates negative ions that eliminate static and
secondly, 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 "Piezo Effect” damping
properties. The resulting Nano Crystal² Formula is the ultimate
electrical and mechanical damping material – only found in Furutech
Nano Crystal² Formula eliminates static, "interconverts” thermal,
mechanical and electrical energy and damps vibrations—all for the finest
Furutech Pure Transmission signal imaginable.
Floating Magnetic Field Effects
The Furutech Earth/Ground Jumper System
How far will Furutech’s engineers go in their attempts to reach Pure
Transmission reference quality? Their concentrated examination of each
and every element of signal transfer has resulted in another
breakthrough technology, the Furutech Earth/Ground Jumper System. It
eliminates EMI (Electromagnetic Interference) induced in metal parts
like connector housing screws.
Current flowing through the power connector creates a magnetic field,
just as an insulated conductor creates both electromagnetic and
electrostatic fields. Furutech engineers found this magnetic field
induces current flow (and a 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 neatly
solves the problem. The Earth/Ground Jumper System connects the securing
screws to a ground terminal within the plug completely eliminating the
field disturbances they cause. The stray fields are grounded by a series
of interlocking parts within the connector that attach to the ground
conductor. The Jumper System is available in Furutech NEMA Power and IEC
Connectors. The Earth/Ground Jumper System Carries US Patent No.
