Jack TRS connectors belong to a family of electrical connectors most commonly used for analogue audio signals. TRS stands for tip/ring/sleeve: the tip is the end of the plug, the ring is the middle section located between the two plastic dividers, and the sleeve is the rest of the metal part of the plug. Each part of the plug is electrically isolated from the others, allowing one plug to carry more than one signal.

Jack connectors are also available in mono (TS) and three-channel (TRRS) versions, depending on the number of channels required for the application.
