Coaxial cables are an essential component of medical equipment, enabling the reliable transmission of high-frequency signals between different components. Medical equipment requires coaxial cables that are designed to meet specific requirements such as frequency range, signal strength, and environmental factors. In this article, we will discuss the different types of coaxial cables used in medical equipment.
RG-58
RG-58 is a type of coaxial cable that is commonly used in medical equipment applications. It has a solid copper core, a polyethylene dielectric, a braided shield, and an outer PVC jacket. RG-58 cables have a frequency range of up to 1 GHz and are relatively low cost. They are commonly used in applications such as ultrasound machines and medical imaging equipment.
RG-142
RG-142 is a high-performance coaxial cable that is commonly used in medical equipment applications. It has a silver-plated copper core, a PTFE dielectric, a double-braided shield, and an outer FEP jacket. RG-142 cables have a frequency range of up to 5 GHz and are suitable for high-frequency applications such as MRI scanners and CT scanners.
RG-174
RG-174 is a miniature coaxial cable that is commonly used in medical equipment applications. It has a solid or stranded copper core, a polyethylene dielectric, a braided shield, and an outer PVC jacket. RG-174 cables have a frequency range of up to 1 GHz and are commonly used in applications such as endoscopes and other medical diagnostic equipment.
RG-316
RG-316 is a high-performance coaxial cable that is commonly used in medical equipment applications. It has a silver-plated copper core, a PTFE dielectric, a double-braided shield, and an outer FEP jacket. RG-316 cables have a frequency range of up to 10 GHz and are suitable for high-frequency applications such as medical telemetry and wireless monitoring systems.
LMR
LMR (Land Mobile Radio) is a type of coaxial cable that is commonly used in medical telemetry and wireless monitoring systems. It has a foam polyethylene dielectric, a braided shield, and an outer PVC jacket. LMR cables are flexible, lightweight, and have a frequency range of up to 6 GHz.
Semi-rigid Coaxial Cables
Semi-rigid coaxial cables are used in medical equipment applications that require a high degree of precision and stability. They have a solid copper core, a PTFE dielectric, and an outer copper jacket. Semi-rigid coaxial cables are commonly used in applications such as microwave ablation systems and other surgical equipment.
In conclusion, coaxial cables are a critical component of medical equipment, enabling the reliable transmission of high-frequency signals. RG-58, RG-142, RG-174, RG-316, LMR, and semi-rigid coaxial cables are some of the commonly used types of coaxial cables in medical equipment, each designed for specific requirements and applications. The selection of the appropriate coaxial cable is critical to ensure optimal performance and reliability of medical equipment.
