FASTON terminals are connectors that are widely used in electronic and electrical equipment. These terminals are manufactured by many companies, commonly using the term "quick disconnect", "tab" terminals, or

blade connector Components of an electrical circuit are electrically connected if an electric current can run between them through an electrical conductor. An electrical connector is an electromechanical device used to create an electrical connection between ...

s. The terminals are often called "quick disconnect" because the predecessors were screw terminals, which took longer to disconnect. The name "tab" terminals is a description of the shape of the male terminal. Six series are available, named after their blade width in inches. Insulated versions of the terminals are color-coded to indicate what

mounted versions of both tabs and receptacles. A little-known hand tool exists for inserting the terminals, the AMP Universal Handle. They have been commonly used since the 1970s. Faston is a trademark.

Specifications

* PIDG FASTON (Nylon) terminals are defined in AMP Specification 114-1002: Terminal, FASTON, PIDG, Application of * PLASTI-GRIP (Vinyl) (insulation restricting) terminals are defined in AMP Specification 114-1003: Terminal, FASTON, PLASTI-GRIP, Application of * UL 310 "Standard for Electrical Quick--Connect Terminals" * CSA 22.2 #153, “Quick--Connect Terminals” * UL 486 also specifies the testing of standard wire connectors and soldering lugs. * MIL-T-7928

Crimp styles

Four main styles of crimps are specified by AMP: * "F" Crimp for use on non-insulated connectors * TETRA-CRIMP for use on insulated PIDG and PLASTI-GRIP connectors * "C" Crimp, typically used for flag connectors (where the wire enters the connector perpendicular to the direction of tab insertion) * Tab-Lok, typically used for flag connectors

Wire gauge insulation colors

The colors don't provide information about the polarity of the crimped cables but specify their

diameter In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid fo ...
