Q: What connector is suitable for multimeter test lead interfaces that need to be compatible with different ranges?

A: Choose banana plug series connectors (4mm diameter), which are compatible with common multimeter ranges (e.g., voltage, current, resistance) and have a plugging force of ＜10N for easy test lead replacement (e.g., damaged leads, special leads for different ranges). The contacts are copper-plated for low contact resistance and a test accuracy of ±0.1%, and the insulating material is PA66 (temperature resistance -20~80℃, suitable for laboratory environments). It also has a misplug protection design with color-coded interfaces for different ranges to avoid operational errors.
