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.
