Flex cables, also known as flexible flat cables or FFCs, are characterized by their ability to connect electrical components while maintaining a flexible structure. This flexibility allows them to navigate through tight spaces and conform to various layouts within electronic devices, making them essential in modern electronic design.

The role of flex cables typically involves interfacing between different electrical components, such as circuit boards, displays, and connectors. Their design facilitates a compact arrangement of components, which is particularly useful in devices where space is a premium, like laptops and smartphones.

While there are other cables designed specifically for power supply or connecting sensors, the defining feature of flex cables is their versatility in the interface between components rather than serving a single dedicated function. Therefore, the statement regarding their purpose as interconnectors aligns perfectly with the context and function of flex cables in electronic applications.
