Ribbon cables Manufacturers online

Ribbon cables are special cables in which several insulated conductors (copper or aluminum wires) run parallel to each other in a flat arrangement.

They are widely used in many electronic applications, especially where a high density of connections is required in a small space.

Below you will find the structure, properties and applications of ribbon cables, as well as their advantages and disadvantages:

Structure and properties:

Ribbon cables consist of several conductors arranged in parallel, which are usually embedded in a flexible plastic housing.
Number of conductors: The number of conductors varies and is often a multiple of 2 (e.g. 8, 16, 24, 40).
Flexibility: These cables are usually very flexible, making them ideal for applications where they need to be bent or folded.

Applications of ribbon cables:

Ribbon cables are often used in applications where many connections are needed in a small space, and they are particularly used in the following areas:

1. Computers and electronics:
Ribbon cables are widely used in PCs, especially for internal connections between hard disks, floppy disk drives and motherboards (e.g. older IDE or ATA cables).

2. Industry:
In machinery and equipment where space-saving and flexible cabling is required.

3. Telecommunications:
Are used for connections in communication devices and systems where many cables need to be brought together in a confined space.

4. Medical devices:
In medical technology applications where compact and reliable cable connections are required.

5. Automotive industry:
Ribbon cables are also used in vehicles, especially in the control of electronics and sensors.

Advantages of ribbon cables:

• The flat shape allows many connections to be routed in a small space. Ideal for confined areas or in devices with limited space.
• They are easy to organize and place as they are flat and can be easily routed in cable ducts or under components.
• Multiple cores (wires) are bundled into a single cable, which simplifies cabling and reduces installation errors.
• Ribbon cables are flexible and can be easily bent, making them ideal for moving or space-critical applications.
• The individual wires are often colored or marked differently to make it easier to identify the conductors.

Disadvantages:

• The flat design can be susceptible to mechanical damage, especially if handled improperly.
• In some cases, signal interference can occur due to the close arrangement of the conductors, especially at high frequencies.

Ribbon cables are therefore ideal for applications where many signals need to be transmitted in a small space and where the flexibility of the cable is an advantage.

Below you will find an overview of the most important criteria that you should pay attention to when purchasing ribbon cables:

When purchasing ribbon cables, there are several important factors to consider to ensure that the cable is suitable for the desired application.

• The number of conductors in the cable should match the number of connections you need. common configurations are 10, 16, 20, 26, 34, 40 or 50 conductors.
• Depending on whether the cable is to transmit data, power or both, the number of conductors required may vary.
• The cross-section of the individual conductors determines how much current the cable can safely transport. common sizes are 28 AWG to 24 AWG. Smaller AWG numbers mean thicker conductors and therefore higher current-carrying capacity.
• The pitch between the individual conductors (usually 1.27 mm or 2.54 mm) should be compatible with the connectors used.
• Copper is the most common material because of its good conductivity, but copper-coated aluminum (CCA) is also sometimes used.
• The insulation should meet the requirements of the environment (e.g. temperature resistance, flexibility). PVC is common, but there are also high temperature resistant materials such as PTFE. Pay attention to the specified temperature range, especially if the cable is used in environments with extreme temperatures.
• When used in demanding environments, the cable should be resistant to moisture, chemicals or mechanical stress.
• If the cable has to be moved or bent frequently, it should have a high degree of flexibility to prevent breakage or damage.
• Shielding can be important for applications where electromagnetic interference needs to be minimized. However, ribbon cables are often unshielded as they are typically used for internal connections where the susceptibility to interference is lower.
• The cable should match the connectors used. IDC connectors are most common for ribbon cables, and it is important that the pitch and number of conductors are correct.
• Look for any certifications, such as UL (Underwriters Laboratories), that indicate tested safety.

These factors help to select the right ribbon cable for the specific application and ensure that it works reliably and efficiently.
