The XLR connector is a type of electrical connector primarily used in professional audio, video, and stage lighting equipment. XLR connectors are cylindrical in design, with three to seven connector pins, and are often employed for analog balanced audio interconnections, AES3 digital audio, portable intercom, DMX512 lighting control, and for low-voltage power supply. XLR connectors are included to the international standard for dimensions, IEC 61076-2-103. The XLR connector resembles the DIN connector, but is larger, more robust and is physically incompatible with it.

XLR-LNE three-pin male and female connectors, originally used for mains power connections. The connecting pins in the male connector are recessed and the sockets in the female connectors are shrouded for safety. This example is a panel socket, used as a power input from the male plug, though they were also used in the opposite configuration.

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 parts of an electrical circuit, or between different electrical circuits, thereby joining them into a larger circuit.
