Coax plugs, also known as coaxial connectors, are widely used in electronic devices for audio and transmission. These connectors are designed to provide a secure and reliable connection between coaxial cables and the devices they are connected to. Coax plugs are typically made of metal, such as brass or nickel, which ensures durability and good conductivity. They feature a threaded outer shell that allows for easy and secure attachment to the corresponding socket on the device. Inside the plug, there is a centre pin that makes contact with the centre conductor of the coaxial cable, while the outer shell makes contact with the shield of the cable, providing a complete electrical connection. Coax plugs come in various types and sizes, including BNC, F-type, and PL-259.
