Solderless QuickConnect Design Experience immediate wiring with our 4mm banana connectors. Simply insert your wire and press to secure the connection. No soldering required, saving time on electrical projects. Current Brass Construction Built with solid brass conductors, these banana connectors provide low resistance and stable conductivity. Suitable for general equipment and current measurement applications that require reliable performance. ColorCoded Identification Five distinct colors red, black, yellow, green and blue help organize your setups and reduce wiring errors in complex electrical systems and instrument connections. HeatResistant Plastic Housing The engineering plastic shell maintains integrity across a wide temperature range, preventing deformation and color changes while providing electrical insulation for safe operation in demanding industrial environments. Typical applications Lab bench testing and instrumentation setups using power supplies, multimeters, and other measurement devices that benefit from rapid, solderless connections. Automotive and industrial equipment harness testing where current and reliable connections are required. Educational environments and calibration tasks where color coding aids lead management and avoids incorrect connections.
