About the product
Specification
The 4mm banana plug features a thick gold plated surface over brass base material. Gold plating resists oxidation and maintains consistent low contact resistance below 10mΩ. This ensures accurate readings for test equipment and clear sound for audio applications.
High purity oxygen free copper strands minimize resistance and power loss. Stranded construction provides flexibility while maintaining current carrying capacity up to 15 amps. Outperforms copper clad aluminum or steel core alternatives available from lower quality suppliers.
Stackable design, easily expand test connections
Cross hole design on the plug body allows stacking multiple banana plugs into a single binding post. This feature is essential for test engineers who need to connect multiple test leads or daisy chain signals without additional adapters.
About the product
Construction and Material
The 4mm banana plug cable consists of four parts: plug, conductor, insulation, and jacket. The plug uses a brass base with gold plating over 3μm thick, ensuring no oxidation during long term use. The conductor uses stranded oxygen free copper for high flexibility and stable conductivity. The insulation uses PVC or silicone material with excellent wear resistance and temperature tolerance.
Electrical Performance
Rated voltage from 300V to 600V, rated current from 10A to 15A, contact resistance below 10mΩ, insulation resistance above 100MΩ. Each cable undergoes 100% continuity and hi-pot testing before shipment to ensure consistent quality.
Mechanical Performance
Plug insertion and extraction life exceeds 10,000 cycles. Cable flex testing exceeds 5,000 cycles. Strain relief design prevents wire breakage at the plug entry point, extending service life.
