What connector uses a twist lock with a bayonet mechanism suitable for high-resolution signals over coaxial cable?

The BNC (Bayonet Neill-Concelman) connector is designed with a twist-lock mechanism that secures the connection through a bayonet fitting. This feature is particularly useful for high-resolution signals transmitted over coaxial cables, as it ensures a reliable and stable connection while also making it easy to connect and disconnect. The design helps to prevent accidental disconnection and maintains the integrity of the signal, which is crucial for applications such as video and audio transmission in professional AV environments. Its ability to handle bandwidths sufficient for high-resolution signals further cements its position as a favored choice in many AV setups.

In contrast, the RCA connector, commonly used for audio and video connections, lacks the twist-lock feature and is not as secure for applications demanding consistent high-resolution signal integrity. The SMA connector is primarily used for microwave applications and does not typically handle the same kind of coaxial high-resolution signals. The F connector is generally associated with cable television and broadband applications and is not designed with the same durability and locking mechanism as the BNC.
