Coaxial Cable Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

A coaxial cable is a specialized electrical cable consisting of a central conductor, dielectric insulator, metallic shield, and outer jacket, designed to transmit high-frequency signals with minimal loss and electromagnetic interference. In industrial probes, it ensures accurate signal transmission for measurement, testing, and data acquisition applications.

Working Principle

Coaxial cables operate on the principle of electromagnetic wave propagation within a shielded structure. The central conductor carries the signal, while the surrounding dielectric maintains impedance consistency, and the metallic shield prevents external interference and signal leakage, enabling stable transmission over distances.

Materials

Central conductor: Copper or silver-plated copper; Dielectric: Polyethylene (PE), polypropylene (PP), or PTFE; Shield: Braided copper or aluminum foil; Outer jacket: PVC, polyethylene, or fluoropolymers.

Frequently Asked Questions

What is the difference between 50Ω and 75Ω coaxial cables in probes?

50Ω cables are optimized for power transmission and minimal loss in RF and measurement applications, while 75Ω cables are used for video and data signals where impedance matching is critical.

How does shielding affect coaxial cable performance in industrial environments?

Effective shielding (e.g., braided or foil) reduces electromagnetic interference (EMI) and crosstalk, ensuring signal integrity in noisy industrial settings like manufacturing floors.
