Gang Disconnect

A connector that permits the rapid and simultaneous connection and disconnection of two or more electrical circuits.

Gang Loading Machines

The concept is similar to the track machines, but the pins/terminals here are in chain form and a specified length is cut and inserted at the same time. The speeds and rates of production are similar to those of track machines.

Gap Loss

In fiber optics, a power loss caused by deviation from optimum flush spacing between the elements of the fiber junction, fiber-to-fiber junction, or fiber-to-element junction. Gap loss is expressed in decibels.

The characteristic of a contact which is impervious to ingress by corrosive gases.

Gate

  1. An electrode, the control element of an FET, 5CR, or TRIAC.
  2. In digital logic, a circuit that has two or more inputs and one output. The output depends on the combination of logic signals at the inputs. The four basic types are called: AND, OR, NAND, and NOR.

Gate Array

An integrated circuit that contains an array of digital logic gates arranged in a pattern.

Gauge

A term used to denote the physical size of a wire. Sometimes spelled "gage."

See also AWG.

Geophysical Cable

Cable used in exploring for underground oil deposits.

GG

Ground-to-ground

Giga

A prefix used to designate one billion times.

Gigabit Ethernet

A Local Area Network (LAN) protocol that supports data transfer rates of 1 Gb/s.

Gigabits

One billion bits. Usually a measure of memory capacity.

Gigahertz

See Hertz.

GIGO

Garbage In, Garbage Out. An common acronym that suggests if you feed poor information into a computer, the computer will most likely output poor information.

Gimmick

A short length of wire that is soldered onto a circuit component and used as a small adjustable capacitor. A gimmick is often two short insulated wires that are twisted together to form a capacitor.

Glass

In fiber optics, an amorphous transparent or translucent brittle material usually made by fusion of silica, soda ash, lime, and salt cake or similar materials. Used as a fiber optic cable, glass offers resistance to high temperatures. It is not subject to corrosion, and eliminates fire hazards and short circuits.

Globule Test

A solderability test specifically for component leads. The time required for a globule of solder to completely wet around a component lead is measured, recorded, and compared against a known standard. This particular test requires a certain amount of human evaluation.

Glow

The sustained light and heat from a poor or broken connection or circuit.

GMV

Guaranteed Minimum Value

gnd

 See Ground.

Go-thru Interconnect System

A Premium line product capable of interconnecting several PCBs in a parallel manner.

Gold

The standard noble metal coating for edge connectors, over a base of either nickel or copper. The common plating consists of 30 micro inches of gold over either 20 micro inches of nickel, or 50 micro inches of copper.

See Plating.

Gold Measurements

In view of its cost there are additional controls on gold. Premium line measures the amount of gold in a tank by using an atomic absorption (AA) machine to determine the "weight of gold per litre" (called gold concentration) of gold solution. Knowing the volume of the tank, we can compute the weight of gold in the tank The amount of gold on a pin/terminal can be measured by chemically removing the gold into a solution and then determining its concentration.

GOR

Gasoline and Oil-resistant wire.

GPS

Global Positioning System

Graded-Index Fiber

Fiber design in which the refractive index of the core is lower toward the outside of the fiber core and increases toward the center of the core; thus, it bends the rays inward and allows them to travel faster in the lower index of refraction region. This type of fiber provides high bandwidth capabilities.

GRAM

Graphics Random Access Memory

Grd

Abbreviation for Ground.

Grid

  1. The distance between any two terminals, in both the x and y directions in Premium line round and plug and receptacle connectors.
  2. An orthogonal network of two sets of parallel equidistant lines used for locating points on a printed board. Connections should be located on the crosspoints of the gridlines.

Grid-spaced

Contacts in a multiple-contact connector or on the edge of a PCB which are spaced equally in a rectangular pattern.

Grommet

  1. A rubber seal used on the cable side of a multiple-contact connector to seal the connector against moisture, dirt, or air.
  2. An insulator, usually of elastomer material, that covers the rear portion of the contacts and a short length of the incoming wire.

Groove

  1. Slot or cavity in a connector which bears directly on the cable.
  2. Depression in a crimping die that holds the connector during crimping.

Ground

  1. A common or reference point in an electrical circuit that can be earth ground and/or a chassis. It is with respect to this common point that all voltages are measured.
  2. A conducting connection between an electrical circuit and the conducting body. A ground completes the electrical circuit.

Ground Loop

  1. A completed circuit between shielded pairs of a multiple pair cable, created by random contact between the shields.
  2. An undesirable circuit condition in which interference is created by ground currents when grounds are connected at more than one point.

Ground Potential

A circuit, terminal, or chassis is said to be at ground potential when it is used as a reference point for other potentials in the system.

Ground Wire

A conductor leading from equipment to an electrical connection with the ground.

Grounded

Connected to ground, or to earth or some other large conducting body.

Grounding Conductor

A conductor in a transmission cable or line that is grounded.
