Coaxial connectors are electrical connectors designed to join coaxial cables, which consist of a central conductor surrounded by an insulating layer and an outer conductive shield. These connectors are commonly used in various applications, including television, internet, and radio communications, to transmit high-frequency signals with minimal interference. The most common types of coaxial connectors include BNC, F-type, and N-type connectors. Each type has specific uses and characteristics, such as ease of connection and durability. Properly connecting coaxial cables with these connectors ensures optimal signal quality and performance in electronic systems.
