BNC-M (5mm) Connector

A BNC-M (BNC Male) connector for 5mm cable is a miniature radio-frequency connector used for quick and secure coaxial cable connections. The "5mm" specification typically refers to the compatible cable diameter, such as RG-58, RG-174, or LMR-100 coax.

These connectors feature a bayonet-style shell with two lugs that lock into place with a simple quarter-turn. They are designed to maintain constant 50-ohm or 75-ohm impedance across the connection, which helps prevent signal loss.
