NCF Piezo Ceramic Series Connectors • A Furutech First!
Furutech’s Pure Transmission CF-C15 NCF(R) & FI-50M NCF(R) Piezo Ceramic series connector bodies and housings feature several breakthrough construction techniques.

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, Piezo Ceramic and Carbon Powder

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

The Furutech Floating Field Damper System
Magnetic Floating Field Damping Current flowing through a cable and its connector creates magnetic (and electrostatic) fields around them, building and collapsing 60 times per second in 120VAC systems. This magnetic field induces current flow– electrical potential–in small parts like the screws holding the connector shell together which have to be metal for tight clamping. The current flow in these small parts actually creates “floating” magnetic fields around them, and they interfere with the cable/connector’s larger surrounding magnetic field resulting in noise and distortion. The Furutech Floating Field Damper solves the biggest problem you never realized you had by star grounding the metal parts in which floating magnetic fields are induced by current flow. All the various metal parts of the connector are tied together and shunt whatever electrical potentials generated to ground. This significantly lowers noise by reducing distortion for ultra-clean and stable power transfer.
