AUDIO FREQUENCY - The range of frequencies audible to the human ear, approximately 20 to 20,000 Hz.
AUTO PRIMARY WIRE - A single or multi-conductor wire used for original equipment or replacement on automotive products. Normally low voltage, resistant to oil, acid, and weather.
AWG - Abbreviation for American Wire Gauge. The system most commonly used in the United States for describing the size of copper wire. It is based on the circular mil system. One (1) mil equals 0.001 inch. Also referred to as the Brown and Sharpe (B&S) wire gauge.
AWM - Designation for appliance wiring material.
B - Symbol for susceptance. See susceptance.
B & S GAUGE - Brown and Sharpe wire gauge used for describing different sizes of copper conductors. It is the same as AWG (American Wire Gauge). See AWG.
BACKBONE - A transmission network that carries information in a fiber optic system. Mainly for indoor applications between floors and areas with different types of cables.
BACKSHELL MOLD - An aluminum mold used to mold a rubber or Neoprene® covering over the backshell of a conductor or plug after it is connected to a cable. The compound is usually chemically cured. Neoprene® is a trademark of the DuPont de Nemours Co.
BALCO® - An alloy of 70% nickel and 30% iron. It is used in devices where self-regulation by temperature is required. Wilbur Driver Company trademark for a resistance wire.
BANDED CABLE - Two or more cables which have been banded together by stainless steel strapping.
BANDMARKING - A circular band applied at regular intervals to the insulation of a conductor for the purpose of color coding or circuit identification.
BANDWIDTH - The frequency range of transmitted electrical or optical signals, expressed in Hertz. The greater or higher the bandwidth, the greater the information carrying capacity.
