FI-52(R) High End Performance Power AC Connector (20A) IEC

Furutech’s Pure Transmission Piezo Ceramic series connector bodies and housings feature several breakthrough construction techniques. A multilayer nonmagnetic stainless steel and carbon fiber shell incorporates a special damping and insulating acetal copolymer. Furutech settled on stainless and carbon fiber for the outer housing after extensive listening sessions with Japanese industry figures and audiophiles.
The body of the connectors combines two “active” materials: Nano-sized ceramic particles and powdered carbon. (Only nano-sized ceramic particles effectively couples with carbon powder.) Nylon and fiberglass are incorporated as well forming an extremely effective, well damped, mechanically and electrically non-resonant connector body. That’s correct, they’re electrically damped as well.
Piezoelectric effects are the key. Furutech’s breakthrough in design and materials is based on employing nano-sized polycrystalline ferroelectric ceramic particles exhibiting electro-generative properties; mechanical pressure creates an electrical charge forming a bridge between electrical and mechanical oscillation.
Carbon powder exhibits thermal-conductive characteristics that interact with the charged ferro-ceramic particles converting their energy into heat that’s conducted away and released from the surface of the connector body!
These carefully chosen and tested “active” materials mechanically and electrically damp the connector and receptacle as they “interconvert” thermal, mechanical, and electrical energy for the finest Furutech Pure Transmission signal imaginable.

Furutech Pure Transmission Philosophy •
Meticulous build quality is a large part of the engineering equation. Furutech Pure Transmission technology turns a macro lens on every element of power and signal transfer applying optimized engineering solutions to well-known problems such as contact resistance, EMI and RFI rejection, grounding, and using the best materials and processes available.

Floating Magnetic Field Effects •
The Floating Field Damper completely solves the biggest problem you never realized you had by star grounding the metal parts in which floating magnetic fields are created by current flow through the connector. A precisely engineered, sprung metal bridge ties the various parts together and shunts the potential to ground, significantly reducing distortion for ultra clean and stable power transfer.
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 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. 6,669,491
