## Long description

GOOBAY adapter with a BNC male connector on one end and two 4 mm banana female sockets on the other. Contacts are gold-plated to improve conductivity and corrosion resistance. Color-coded black and red for easy polarity identification. Suitable for connecting test equipment, audio gear, or laboratory instruments that require conversion between a BNC connection and dual banana leads.
Advantages
The adapter provides a compact mechanical and electrical interface for converting a standardized BNC connection to two 4 mm banana sockets. Gold-plated contacts reduce contact resistance and improve corrosion resistance for stable signal transfer. The color-coded banana sockets simplify correct polarity connection. The construction is designed for straightforward, low-profile use in bench setups and audio or measurement signal chains.
Suitable for
Connecting oscilloscopes, signal generators or multimeters to banana-leaded probes
Adapting audio or RF test points with BNC outputs to banana-terminated cables
Laboratory and educational bench experiments requiring quick conversion between BNC and banana connectors
Key specifications
Connector type (input): BNC male, straight
Connector type (output): 2× 4 mm banana female, straight
Contact plating: gold-plated contacts for improved conductivity and corrosion resistance
Color coding: black and red banana sockets for polarity identification
Intended use: signal/adaptation for audio, RF, test and measurement equipment
How to use
Insert the BNC male connector into the corresponding BNC socket until it locks with the bayonet coupling. Connect banana-terminated leads into the red and black 4 mm banana female sockets according to the required polarity. Verify that both connections are secure before applying signals or powering connected equipment. Disconnect by removing banana plugs and unlocking the BNC coupling when work is complete.
Usage recommendations
Use the adapter in low-voltage signal applications and measurement environments. Avoid exposure to moisture and mechanical stress; ensure banana plugs and the BNC coupling are fully seated to maintain reliable contact and minimize signal loss.
