A confined crimp that makes two longitudinal indentations which form a W cross section.
A soldered terminal that provides solder connection points at both sides of a terminal block.
Premium line trademarked shrouded and unshrouded headers, pre-assembled to a PCB that mates to Premium line .093" standard receptacles.
A term used that expresses the thickness of a layer of applied insulation or jacket.
Wide Area Network. A network that allows LANs to communicate over a wide area, generally spanning a geographic area wider than a single city.
A unit of electrical power. One watt is equivalent to the power in work per unit time required for one ampere of current to flow under an electrical voltage difference of one volt in a DC circuit.
A unit of energy.
An electrical instrument used to measure power.
A process by which items to be soldered are brought in contact with a gently overflowing wave of liquid solder that is circulated by a pump in an appropriately-designed solder pot reservoir.
A graphical representation of a varying quantity. Usually, time is represented on the horizontal axis, and the current or voltage value is represented on the vertical axis.
Wavelength Division Multiplexer
See WDM.
Wavelength Division Multiplexer. A passive device that transmits signals at different wavelengths through the same fiber.
Metal-to-metal lead bond formed by a wedge-shaped tool. It may be a cold weld, ultrasonic, or thermal compression bond.
A connector in which the contact between the conductor and the connector is made by pressure exerted by a wedge.
A process in which the oxide layer covering a metal surface is eliminated, and the joining surfaces of the two substrates are brought into intimate contact with sufficient heat energy to cause thermal diffusion of both metals across an interface, resulting in the development of a heterogeneous layer or zone between the surfaces, thus creating a strong inter-atomic metal alloy bond there.

See FCC Plug.
The formation of a relatively uniform smooth, unbroken, and adherent film of solder to a base material.
A single crystal growth resembling fine wire, which appears most frequently on components that have been electroplated with tin. Whisker growth requires no voltage.
Desoldering method that utilizes pre-fluxed braid of stranded wire, or braid used with flux. The wick material is placed on the solder joint and a heated iron tip is applied to the wick. Capillary action draws the solder up into the wick material.
On flat cable, the distance between edges of the cable.
The translational action that occurs when contacts are mated with a sliding action. Wiping has the effect of removing small amounts of contamination from the contact surfaces, thus establishing better conductivity. The distance the wiping occurs on a contact is referred to as wiping length.
A solid or stranded group of conductors that has a low resistance to current flow, together with any associated insulation.
A type of terminal configuration. The two main categories of wire barrel are open barrel and closed barrel terminals.
The joining of components (wire, metal bonding surfaces, underlying insulating layer, and substrate) of wire electrical connection.
See AWG.
A device that measures, cuts, forms, bends, strips, and straightens wire leads. These devices vary from simple hand or bench-style tools to high-speed equipment.
The force required to separate a wire from a contact to which it has been attached by solder, IDT, crimping, or welding.
Usually, the sum of wire size (AWG) plus insulation diameter. For crimped tooling, also the strip length.
A stop at the end of a terminal wire barrel that prevents wire from passing completely through the barrel so the wire will not interfere with the function of the contact.
Table of sizes and properties of round copper wire.
See also AWG.
A Premium line .098" (2,5 mm) connector system that mechanically holds stripped cable in a simple but very effective manner.
A termination method in which discrete wire is tightly wrapped around an angular, usually square, post (also called a terminal or wire wrap tail). Wire wrap terminals are available in one, two, or three-wrap lengths.
Building space for telecommunications equipment, data communications equipment, cable, terminations, cross-connect intelligent hubbing devices, and administration subsystems. Wiring closets are located at the interface point between the backbone cabling and the horizontal wiring.
The force required to disconnect two halves of a connector.
Test voltage that an electrical connector withstands for one minute without electrical breakdown. The voltage is applied between conductors and grounding devices of connectors in various combinations.
The number of bits that one CPU register can store. Word size is usually the same as the width of the data bus. Most bytes in computers are eight bits, so a word is usually a multiple of eight. Common sizes are two eight-bit bytes (16 bits) or four eight-bit bytes (32 bits). Larger computers may have 64-bit words.
A graph that plots the pull-out force, indent force, and/or relative conductivity of a crimp joint as a function of various depths or distances, a measure of pull-out/indent/crimping deformation. The work of pull-out/indentation/crimping, deformation, etc., is then determined via the area under the curve.
The maximum recommended voltage for continuous use.
