Fencing
Electric equipment

A set of electric fencing equipment is required to participate in electric fencing. Electric equipment in fencing varies depending on the weapon with which it is used in accordance. The main component of a set of electric equipment is the body cord. The body cord serves as the connection between a fencer and a reel of wire that is part of a system for electrically detecting that the weapon has touched the opponent. There are two types: one for épée, and one for foil and sabre.

Épée body cords consist of two sets of three prongs each connected by a wire. One set plugs into the fencer's weapon, with the other connecting to the reel. Foil and sabre body cords have only two prongs (or a twist-lock bayonet connector) on the weapon side, with the third wire connecting instead to the fencer's lamé. The need in foil and sabre to distinguish between on and off-target touches requires a wired connection to the valid target area.

A body cord consists of three wires known as the A, B, and C lines. At the reel connector (and both connectors for Épée cords) The B pin is in the middle, the A pin is 1.5 cm to one side of B, and the C pin is 2 cm to the other side of B. This asymmetrical arrangement ensures that the cord cannot be plugged in the wrong way around.

In foil, the A line is connected to the lamé and the B line runs up a wire to the tip of the weapon. The B line is normally connected to the C line through the tip. When the tip is depressed, the circuit is broken and one of three things can happen:

In Épée, the A and B lines run up separate wires to the tip (there is no lamé). When the tip is depressed, it connects the A and B lines, resulting in a valid touch. However, if the tip is touching the opponents weapon (their C line) or the grounded strip, nothing happens when it is depressed, as the current is redirected to the C line. Grounded strips are particularly important in Épée, as without one, a touch to the floor registers as a valid touch (rather than off-target as in Foil).

In Sabre, similarly to Foil, the A line is connected to the lamé, but both the B and C lines are connected to the body of the weapon. Any contact between one's B/C line (either one, as they are always connected) and the opponent's A line (their lamé) results in a valid touch. There is no need for grounded strips in Sabre, as hitting something other than the opponent's lame does nothing.

In a professional fencing competition, a complete set of electric equipment is needed.

A complete set of foil electric equipment includes:

The electric equipment of sabre is very similar to that of foil. In addition, equipment used in sabre includes:

Épée fencers lack a lamé, conductive bib, and head cord due to their target area. Also, their body cords are constructed differently as described above. However, they possess all of the other components of a foil fencer's equipment.
