Type of Connector: BNC connectors are miniature, quick-connect/disconnect radio-frequency connectors designed for coaxial cables.
Applications: They are widely used in various applications, including video systems (especially CCTV and HD-SDI), radio antennas, test equipment, computer networks (historically), and professional audiovisual equipment.
Impedance: BNC connectors come in two main impedance types: 50 Ohm (for RF and data applications) and 75 Ohm (primarily for video applications).
Mating Mechanism: They feature a bayonet-style coupling mechanism that allows for a secure connection with a quarter-turn twist, making them easy to connect and disconnect.
Common Cable Types: They are typically used with coaxial cables like RG-58 (50 Ohm), and RG-59 or RG-6 (75 Ohm).
