Micro coaxial cables have different types with unique purposes. Hence, knowing how these types differ helps one decide which micro coaxial cable to buy.
The type of micro coaxial cable in this category is a 50-ohm micro coaxial cable. It is ideal for satellite transmissions, radio frequencies, and antennas. These cables are often used in professional settings. This is because they efficiently transmit signals over long distances without much degradation.
High-temperature micro coaxial cables are designed to function under stressful conditions. These cables typically operate at over 200°C. This makes them ideal for environments such as aerospace, oil and gas exploration, kilns, and chemical processing.
As the name suggests, these micro coaxial cables have a 75-ohm impedance. Cable users mainly use them for broadcast and video applications. Examples are cable television (CATV) systems and video surveillance. It helps maintain signal clarity in video transmission. This is because they reduce reflections and signal loss.
These cables come with extra shielding layers to enhance signal protection. For example, they may have a braided metal cover or a foil layer over the core. This makes them ideal for applications in crowded electromagnetic environments where interference is common.
These cables are designed to have lower capacitance than regular coaxial cables. Therefore, they become suitable for high-speed data transmission. Their low capacitance ensures minimal signal attenuation. Often users need these cables in sensitive applications. These include medical imaging systems, high-frequency test equipment, and radar systems.
Micro coaxial cables come with various specifications that demonstrate their performance and applicability. Here's a detailed breakdown, focusing on the key micro coaxial cable features and specifications.
Micro coaxial cables usually have three types of impedance. That is a 50-ohm, 75-ohm, and 93-ohm micro coaxial cable. The 50-ohm cables handle high-power signal transmission, while 75-ohm cables are for video and RF signal transmission. The 93-ohm impedance micro coaxial cables are designed for specific sensitive, high-precision applications.
Micro coaxial cables mainly utilize copper, copper-clad aluminum (CCA), or silver-plated copper as conductor materials. All these materials have different conductivity levels and costs. While copper is highly conductive and durable, silver-plated copper offers better signal quality by resisting oxidation. On the other hand, copper-clad aluminum provides a lighter and more cost-effective alternative with decent conductivity.
The dielectric material affects the cable's insulation and determines how well it can maintain its integrity. Common dielectric materials include polyethene (PE), fluorinated ethylene propylene (FEP), and polyvinyl chloride (PVC). PVC is used for lower frequency applications because it is less expensive. On the other hand, PE offers better insulation for general use. FEP is used when temperature resistance and low dielectric loss are required.
Micro coaxial cables have high levels of protection against environmental factors. These include electromagnetic interference (EMI) and physical wear. Common shielding materials include braided copper, aluminum foil, or a combination of both. While braided copper provides excellent flexibility and durability, aluminum foil offers 100% coverage against EMI.
The outer diameter of micro coaxial cables typically ranges from 1.0 to 3.0 mm. Users prefer smaller diameters in areas where space is limited, such as in medical devices or compact cameras. Conversely, larger diameters offer greater durability and often are preferred for industrial applications.
People often pair micro coaxial cable with other equipment to enhance its function. To illustrate, various tools and devices improve signal clarity and system efficiency in different setups. Below are these setups one should consider.
Video users often pair micro coaxial cables with cameras in video surveillance systems. This is particularly for high-definition (HD) video transmission. The cable's low signal loss and excellent shielding allow it to transmit video feeds over long distances without blurring or losing quality.
Users connect micro coaxial cables to antennas for wireless communication systems. The cables help transmit and receive radio frequency signals. Their precise impedance and minimal signal attenuation make them suitable for maintaining signal strength during transmission and reception.
Devices like oscilloscopes, signal analyzers, and network testers require micro coaxial cables to function well. The cable carries test signals with great precision and minimal interference during equipment testing and calibration. This ensures that the test results reflect the actual equipment performance.
Techs use micro coaxial cables to help them transfer data within medical imaging devices like ultrasounds. The cables' low capacitance and high flexibility make them ideal to fit in the equipment while keeping high signal integrity necessary for detailed imaging.
Micro coaxial cables in satellite communication systems help transmit signals between satellites and ground stations. Users prefer these cables because they efficiently carry high-frequency RF signals over long distances. They also provide low loss and high reliability.
Micro coaxial cables can insulate equipment from interference in signal transmission. This ensures precision in processes such as control systems, robotics, and manufacturing machinery. In control systems, for instance, the cables transmit signals to control precision machinery.
One must consider several factors when selecting an ideal micro coaxial cable. This is especially true if these cables are for clients. Below are these factors.
It is important to note the signal frequency of the application before buying these cables. A cable with proper impedance will support high-frequency signals without losing much signal. Thus, a 75-ohm micro coaxial cable is suitable for video and RF signal transmission. Conversely, 50-ohm cables handle high-power signal transmissions in industrial and satellite communications.
Professionals will know the client's application before buying medical imaging, satellite communication, or video surveillance. Techs will specifically look for flexibility, signal integrity, and durability in medical imaging. However, clients in video broadcasting and surveillance will require cable manufacturers to provide them with extra shielding.
Users with a large-scale operation will look for a cost-effective option that does not compromise quality. For instance, copper-clad aluminum offers excellent conductivity despite being cost-effective. Conversely, silver-plated coaxial cable will be expensive but worth it. After all, they improve performance through better signal quality.
Coaxial cables are sometimes used in extreme environmental conditions that affect their lifespan and performance. For example, aerospace and outdoor oil rigs have high and low temperature and pressure, so do chemical processing environments. That is why high-temperature micro coaxial cables are suitable here. they can handle up to 200°C.
Users in the space industry will prioritize weight as they look for a lightweight yet durable option. Medical professionals also require lightweight cables for imaging devices to ensure easy handling. Copper-clad aluminum is the ideal choice here because it is durable yet lightweight compared to copper.
People require flexibility in micro coaxial cables for their portable devices. For instance, medical equipment and robotics need this flexibility to enhance their maneuverability in tight spaces. Although flexibility often reduces durability, silver-plated copper coaxial balances these two.
A1: Coaxial cables like the micro coaxial cable are maintenance-free. It’s because their internal structure is well protected from environmental elements. However, clients may occasionally recommend inspecting the cables for visible wear or damage, which could affect their performance.
A2: The signal quality is significantly affected by the dielectric and outer shielding material. A high-quality dielectric material maintains signal integrity during transmission. Conversely, a good shielding protects the cable from EMI and other interferences.
A3: Most micro coaxial cables are customized depending on the client's needs. It is because these cables are often used for specialized applications. That is why their lengths are tailored to suit individual clients' needs.
A4: Storing these cables in a cool, dry area free from direct sunlight and extreme temperatures is essential. Furthermore, the cables should be loosely coiled to prevent kinks or bends. In addition, users should avoid storing the cables in areas with high humidity or chemical exposure. Such a storage area can degrade the cable's materials over time.
A5: The micro coaxial cable typically meets IPC-6015 specifications. This specification repairs the demand for these cables to have a maintained quality, reliability, and performance.
