4mm Banana Plug Black + Red

This pair of 4mm banana plugs (one red, one black) is designed to establish safe and quick electrical connections on breadboards and laboratory power supplies. Their standard 4mm diameter ensures compatibility with the vast majority of test sockets and terminal blocks used in electronics.

Ideal for prototyping with Arduino, Raspberry Pi, or any project requiring reliable temporary connections, they facilitate the attachment of test leads without soldering.
