Furutech FI-15E Cu IEC connector with unplated α pure-copper contacts, Floating Field Damper and set-screw termination. For 6.6–13 mm cables up to 3.5 mm². Read more.
The Furutech FI-15E Cu is a high-performance IEC cable connector designed for building or upgrading premium power cables for hi-fi and audiovisual equipment. This Cu version uses unplated α (Alpha) pure-copper conductors, making it particularly attractive for users who specifically prefer a direct copper contact without gold or rhodium plating.
Its robust construction, set-screw termination and Furutech Floating Field Damper System make the FI-15E Cu an excellent solution for high-quality DIY and upgraded audio power cables.
The current-carrying contacts of the Furutech FI-15E Cu are made from pure copper and receive Furutech's α (Alpha) treatment. Unlike many other high-end connectors, the contact surfaces of this Cu version are not finished with gold or rhodium plating.
This makes the FI-15E Cu particularly suitable for enthusiasts who deliberately want to use an unplated pure-copper connection when assembling their power cable.
Furutech equips the FI-15E Cu with its Floating Field Damper System, a construction developed to help reduce the influence of induced magnetic fields around the connector.
The Furutech FI-15E Cu accepts power cables with an outer diameter from 6.6 to 13.0 mm. Conductors up to 3.5 mm² / 12 AWG can be accommodated.
The conductors are secured with set screws, eliminating the need for soldering and allowing a secure mechanical connection when correctly installed.
The main body and outer cover are manufactured from nylon and fiberglass material. Stainless-steel fixing screws provide a strong construction, while overall dimensions of approximately 31.0 × 33.3 × 72.0 mm keep the connector relatively compact.
