MX 4mm Banana Right Angle Male Connector Stackable From Rear Spring Loaded Beryllium Copper (MX-1402)

Stacking connectors - plugging a second, smaller plug into the back of a larger one - is a common way to tap a test point without disturbing an existing connection, and this banana plug is built specifically to support that, accepting a 2mm plug into its rear spring-loaded entry while its own 4mm end stays plugged into the main test point. The right-angle body routes the cable sideways rather than straight out, useful on a crowded bench where connectors need to sit close together. Beryllium copper construction gives the spring contacts better fatigue resistance over thousands of insertion cycles than a standard brass contact would manage, which matters on a connector that's handled constantly during testing.
