A ribbon cable is a thin, flat cable made up of multiple small-grade conductors laid parallel to each other. Each conductor is positioned side by side, forming a wide flat cable that closely resembles a piece of ribbon. These cables feature flexible, low-profile, and colour-coded conductors designed for compact electronic systems and internal wiring. Typical conductor pitch is around 0.05” (1.27mm) or less, allowing precise and efficient wiring in tight spaces.
There are several variations of ribbon cables, each suited to particular requirements and environments. The two primary forms are:
Flat ribbon cables, also known as multiplanar cables, consist of multiple small-grade wires arranged parallel to each other, forming a wide, flat design similar to a ribbon. These cables are primarily used in electronic systems to connect internal peripherals, such as disk drives to their controllers. The colour coding on flat ribbon cables aids in easy identification of connections.
Round ribbon cables feature wires laid flat side by side, often with different colors for easy differentiation. These cables are mainly used for external wiring in electronic devices and consumer products. Their compact design makes them ideal for tight spaces. Round ribbon cables are available in shielded and unshielded options, with varying voltage ratings and capacitance, and the number and size of strands can differ.
Ribbon cables come in various pin configurations, including common counts like 3, 4, 6, 10, 20, 26, and 40+ pins. Typical wire gauges include 22 AWG ribbon cable, 26 AWG, and 28 AWG options. For example, a 4 pin ribbon cable is commonly used in small power and signal applications, while 8 pin ribbon connector cables are popular in data transmission. Matching the right conductor count and wire gauge with compatible connectors ensures optimal performance.
Flat wire refers to a single conductor with a flat profile, different from ribbon cable which bundles multiple conductors side by side. Unlike the multi-wire flat ribbon cable, flat wire is used for simpler connections or power distribution where a single conductor’s flat shape provides space-saving benefits.
Ribbon cable systems often require specific connectors and accessories for efficient installation and reliable performance. Common options include:

Ribbon cables are essential for internal wiring in computers, printers, and consumer electronics. Their compact, organised layout allows efficient connection of multiple data lines between components, ensuring smooth device operation.
In vehicles, ribbon wire is used in wiring harnesses where space is limited. These cables provide reliable data and power connections for electronic control units and sensor systems.
Precision and reliability are critical in medical devices. Flat ribbon cables offer flexible, low-profile wiring for diagnostic machines, monitors, and imaging equipment, supporting accurate data transmission.
Due to their lightweight and compact design, ribbon cables are used in aerospace systems requiring durable, high-reliability wiring that can withstand challenging environments.
