Furutech FI-48 series : High-end performance IEC power connectors

Furutech’s Pure Transmission FI-48 series connectors feature several unique construction techniques.

The beautifully-finished FI-48 series connectors consist of a nylon/fibreglass body incorporating ceramic nano-sized particles and carbon powder that absorb vibration and resonance; a polycarbonate inner cover plate, a beautifully polished aluminium non-magnetic SUS303 housing and metal cable damping clamp with stainless screws.

Furutech is known the world over for a huge variety of top-quality high end audio grade parts and delivers consistently superior results by following Pure Transmission principles; examine every link in the power and signal path and ultimately optimize each and every element

The new FI-48 series features a new plating technique which delivers sonic improvements and a more durable finish

All metal parts are treated with Furutech’s Two Step Cryogenic and Demagnetizing Alpha Process.

The body of those connectors marked as “NCF”, 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 products!

Nano Crystal² Formula eliminates static, “interconverts” thermal, mechanical and electrical energy and damps vibrations—all for the finest Furutech Pure Transmission signal imaginable.

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 Floating Field Damper 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 Floating Field Damper 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 Floating Field Damper System is available in Furutech US Power and IEC Connectors.
