Description
The FI-E11-N1 is a mains plug from Furutech, designed for fitting custom-made hi-fi power cables. This type of connector allows you to make or replace the termination of a mains cord intended to power an audio or video device.
Its front body is made of fibreglass-reinforced nylon, a material valued for its mechanical rigidity, while a polycarbonate shroud completes the assembly. The plug is rated for 16A/250V use, corresponding to a connector intended for household appliances or audio equipment of typical power on the European domestic mains supply.
It is specified to accept cables with a diameter of between 6.6 mm and 16 mm, thanks to a 20 mm clamping screw that secures the cable at the plug's entry point. Its dimensions are 56 mm in length by 39 mm in diameter, with a total length of 88 mm once assembled.
This connector is aimed at enthusiasts wishing to make their own mains cable, or technicians producing custom cords for demanding audio installations, particularly when the diameter of the chosen cable exceeds what standard mains plugs can accept.

What to check before buying used
Check the tightness of the screw at the cable entry: on a unit already assembled, a cord that has been unplugged too often may have loosened the grip or marked the pins. Inspect the nylon/fibreglass body for cracks near the polycarbonate, particularly if the plug has been forced onto a cable close to 16 mm. Also check for signs of overheating around the contacts, an indication of poor contact or use beyond the 16A/250V rating.
