Banana Jack 2 Way

Description

4mm Dual Binding Post Terminal (2-Way Banana Jack Socket) The 4mm Dual Binding Post Terminal (commonly known as a 2-way banana jack socket block) is a heavy-duty electrical connector widely used to bridge power or audio signals. It features a pair of color-coded binding posts (one Red for Positive, one Black for Negative) spaced at the industry-standard 3/4-inch (19mm) distance. This standard spacing allows it to accept both individual banana plugs and integrated dual-banana plug connectors seamlessly. Key Features Connectors: 2 x 4mm Female Banana Jacks / Threaded Binding Posts (1 x Red, 1 x Black). Standard Spacing: Centers are precisely spaced 19mm apart, matching standard dual-position test equipment and patch cords. Versatile Termination: Front: Accepts standard 4mm banana plugs, or unscrews to secure bare wire ends and spade lugs through a cross-hole. Rear: Threaded M5 metal posts with hex nuts and lock washers for heavy-duty ring terminals, or raw solder tabs for permanent internal chassis connections. Electrical Capacity: High-current capable, typically rated for 20A to 30A at 1000V (depending on insulation grade). Material: Nickel- or gold-plated brass conductors embedded in a rigid, insulated plastic crossbar base. Compatibility Guide This dual binding post is a cornerstone component in professional test labs, custom power delivery networks, and high-fidelity audio equipment. 1.
