A BNC connector (Bayonet Neill–Concelman) is a miniature, quick-connect/disconnect radio-frequency connector used primarily for coaxial cables. It features a bayonet-style locking mechanism—a rotating ring that twists and snaps into place, providing a positive, secure connection. Key characteristics include:
Design: Metal body with a central pin and bayonet coupling.
Impedance: Available in 50Ω and 75Ω variants, matching common coaxial cable types.
Frequency Range: Typically supports up to 2–4GHz (HD video and radio-frequency signals).wikipedia+1
Voltage Rating: Generally rated under 500V.
Applications: Used in video transmission (CCTV, broadcast), audio, RF signal connections, data networking, and test equipment.
Other Features:
Reliable, low-loss signal transmission.
Available as weatherproof or indoor-only versions.
Simple push-and-twist operation for quick connection and release.
