What is a Binding Post?
Binding Post Description
Initially invented by the General Radio Corporation of Cambridge, MA, binding posts are commonly used in test fixtures for wire termination. A typical single post binding post consists of a cylindrical threaded stem with a drilled hole for accepting the conductor, one or more molded nuts, and an insulated cap. During installation the conductor (usually stripped copper wire) is inserted through a hole in the threaded stem of the post and tightened into place by using a molded nut. Binding post caps are used to insulate the binding post and come in 3 primary colors: red indicates an active (positive) terminal, black indicates an inactive (negative) terminal, and green indicates the ground terminal.
Binding Post Designs
One common design for binding posts is called a universal or five-way style. This style allows for the joining of multiple types of connectors such as banana plugs, pin connectors, uninsulated wire, and more. Other types of binding posts include insulated binding posts, dual binding posts, knob type binding posts, metal binding posts, miniature binding posts and spring loaded binding posts.

What is a Banana Plug?
Banana Plug Description
Banana plugs are one conductor (aka: single wire) electrical connectors that are traditionally used to connect wires to equipment with DC and low frequency signals. Banana plugs are male connectors that feature a tubular construction with a flared center to separate the wire post from the main connector body.
Since standard banana plugs are normally not insulated, they are only recommended for applications less than 33 volts. However, insulated banana plugs are available for use in higher current applications. One of the many benefits of using banana plugs is their safety and simplicity. Banana plugs also provide secure connections for lead wires.
Banana Plug Applications
Banana plugs’ basic design make them a connector of choice for many applications. In fact, technicians and engineers often use banana plugs in during prototyping to test circuits and connections. Common applications include medical equipment, personal computers, and aircraft navigation systems.

Product Spotlight: Pomona Banana Plugs and Jacks
Banana plugs are single conductor connectors used to carry DC and low-frequency signals and connect wires to equipment. Applications ranging from power supplies to multimeters typically use banana plugs. Standard banana plugs are only used for currents less than 33 volts since they have exposed metal parts. Sheathed banana plugs are rated for use with higher voltages, and are often used as multimeter test leads. Engineers and technicians use banana jacks on custom fixtures, early prototypes, and informal “one-off” projects.
