Furutech FI-11-N1 (Ag) silver-plated high-end IEC connector with α-phosphor bronze, Floating Field Damper and metal cable clamp for a stable power connection. Read more.
The Furutech FI-11-N1 (Ag) is a high-performance silver-plated IEC connector designed for professionally terminating or upgrading premium power cables for audio and video equipment. Furutech combines carefully selected materials with its renowned α (Alpha) technology, a solid metal cable clamp and its Floating Field Damper System.
The FI-11-N1 (Ag) is aimed at demanding audio enthusiasts and cable builders who value a reliable mechanical connection, high-quality power transfer and durable construction. It accommodates cable diameters from 6.6 to 16 mm, making it suitable for a wide range of high-end mains cables.
The current-carrying components of the Furutech FI-11-N1 (Ag) are manufactured from α (Alpha) treated phosphor bronze and finished with silver plating. Furutech applies its Alpha treatment to conductive metal parts with the aim of optimising their material characteristics and electrical performance.
The Ag version is therefore an attractive choice when building a premium power cable where secure contact, low contact resistance and durable connector construction are important.
A key feature of the FI-11-N1 series is Furutech's Floating Field Damper System. This construction is designed to reduce unwanted induced magnetic fields around the connector and contribute to a stable electrical environment.
The FI-11-N1 (Ag) also features a non-magnetic stainless-steel cable damping clamp. This firmly secures the cable and helps control movement and resonance around the cable entry.
With support for cable diameters from 6.6 to 16 mm, the Furutech FI-11-N1 (Ag) can be combined with many high-quality mains cables. According to Furutech, a longer fixing screw allows cables with an outside diameter of up to approximately 20 mm to be accommodated.
Maximum wire accommodation is 5.5 mm² / 10 AWG, while the electrical rating is 10A at 250V AC and 15A at 125V AC.
