Coaxial cables

Product catalog summary

Technical Glossary:

Characteristic Impedance: Defines the voltage-current relationship in a coaxial cable, typically categorized into 50 Ω, 75 Ω, and 95 Ω.
Capacitance: The ability of a coaxial cable to store electric charge, influenced by cable geometry and insulation material.
Velocity of Propagation: The speed at which an electrical signal travels through the dielectric, affected by the dielectric constant.
Attenuation: Represents signal loss during transmission, calculated based on conductor and dielectric losses.

Coaxial Cables Overview:
Coaxial cables are used in applications requiring minimal signal distortion and attenuation, such as aerospace, telecommunications, and medical devices. They consist of a central conductor and shield separated by a dielectric, which prevents external interference and electromagnetic wave loss. The design and performance of coaxial cables depend on materials, diameter, impedance, capacitance, attenuation, and frequency range.

Design and Materials:
AXON’ coaxial cables use materials like copper clad steel, PTFE, and CELLOFLON® for conductors and dielectrics. CELLOFLON® offers high porosity and low dielectric constant, resulting in lighter, more flexible cables with superior electrical characteristics.

Composition and Characteristics:
Coaxial cables are composed of various materials for conductors, dielectrics, screens, and sheaths, each offering specific benefits such as flexibility, mechanical protection, and electrical shielding. The velocity of propagation is typically around 69%.

Applications:
Coaxial cables are essential in minimizing external interference and are used in diverse fields, including military equipment, video systems, and computer systems. They are designed to handle different signal types and frequencies, with specific connectors for various applications.

Overview: This document provides detailed specifications and applications for various coaxial cables manufactured by AXON' Cable. It includes information on materials, construction, and performance characteristics, as well as applications and compliance with standards.

Specifications:

Materials: The cables use materials such as PTFE, FEP, and SPC for conductors, dielectrics, and outer sheaths.
Construction: The document lists various cable constructions, including single and multi-strand conductors, with specific diameters and materials for each component.
Performance: Key parameters include impedance (50, 75, 95 ohms), capacitance (ranging from 50 to 105 pF/m), and attenuation at specified frequencies (e.g., 0.90 dB/m at 400 MHz).

Applications:

High gain audio amplifiers, piezoelectric components, accelerometers, magnetic recording heads, and oscilloscope probes.
Medical electronics, audio equipment, satellites, and miniaturized electronics.
Aerospace, telecommunications, radio/television, video systems, and military equipment.

Compliance and Standards:

The cables comply with the RoHS directive, replacing heavy metals with environmentally friendly alternatives.
They meet various military and industry standards, such as MIL-DTL-17 and NF C 93-550.

Special Versions:

PICOCOAX®: Flexible miniature coaxial cables with small diameters and specific capacitance values, suitable for medical imaging and other applications.
AXOWAVE®: Low-loss microwave assemblies using CELLOFLON® dielectrics, capable of operating at high frequencies up to 50 GHz.

Quality Control and Technical Support:

Includes dimensional, impedance, capacitance, and attenuation tests.
Technical support for terminated coaxial cables and custom designs.

Customer Buying Guide: Essential factors for selecting the appropriate cable include operating temperature, non-flammability, impedance, attenuation, connector type, and application domain.

TECHNICAL GLOSSARY CHARACTERISTIC IMPEDANCE Term representing the relationship between the voltage and current in a cable of supposedly infinite length. There are three main classes of characteristic impedance for coaxial cables : 50 Ω, 75 Ω and 95 Ω. The formula defining characteristic impedance may be written as follows : 138.2 D zc=——— • Log10 — in Ω ∊ √‾ d CAPACITANCE Property of a coaxial cable to store electric charge when a difference in potential energy exists between the two conductors. This will depend on the geometry of the cable and on the nature of the insulation and may be defined...
