I/O Connectors are connectors designed to provide an interface for transferring signals between electronic equipment and external devices or subsystems. They form a defined connection point for input and output paths, supporting reliable mating and unmating while maintaining consistent electrical contact.

Within the broader Connectors category, I/O Connectors typically include standardized interface families and related interconnect styles used to link systems at the board, panel, or cable level.

• Primary role: Establish a detachable electrical interface for signal interchange.
• Connection scope: May support signal-only links or combined signal and power interfaces, depending on the interface standard.
• System integration: Often used as the external-facing connection point that bridges internal circuitry to other equipment.
