4 MM Banana Plug

4 MM Banana Plug is a type of electrical connector commonly used in electronic devices, speakers, and amplifiers. It consists of a cylindrical metal pin, typically made of brass or copper, with a banana-shaped head. The plug is designed to be inserted into a corresponding socket or jack and is held in place by spring tension. Banana plugs are preferred over other types of connectors due to their ease of use, reliability, and ability to be easily inserted and removed. The 4 MM Banana Plug is also commonly used in laboratory settings for test equipment and measurement applications and can be color-coded for easy identification of different connections.
