Ideal for speaker terminals, amplifier outputs, test equipment and custom chassis builds where a secure, lowresistance connection is required. Key benefits Reliable electrical contact: Pure copper contacts with gold plating minimize contact resistance and improve signal transfer over time. Secure mechanical hold: Screw terminal design and 4mm wire hold diameter keep bare wire or ferrules firmly in place. Compact installation: Total length of 32mm and a maximum outer diameter of 14.5mm save panel space while providing a robust connection point. Clean, corrosionresistant finish: Gold plated contacts reduce oxidation for stable longterm performance. Easy to install: Designed for a recommended chassis opening of 6.8mm and straightforward panel mounting. Important features and specifications Model number: 4mm Crystal Type: Banana Socket Contact material: Pure copper, gold plated Total length: 32mm Wire hold diameter: 4mm Screw outer diameter: 7mm Screw shaft length: 12mm Screw shaft diameter: 4mm Maximum outer diameter: 14.5mm Recommended chassis opening: 6.8mm Compatibility and performance Accepts standard 4mm banana plugs and bare wire up to 4mm diameter. Suitable for audio speaker connections, amplifier outputs, and laboratory or bench equipment connections where conductive contact is needed. Robust screw terminal secures wire and maintains contact under vibration and handling. Installation tips Drill a 6.8mm chassis opening for the fit. Strip wire to the appropriate length, insert into wire hold, and tighten screw to secure. Use ferrules for stranded wire to improve mechanical stability. Torque screws moderately to avoid deforming the screw shaft or contact. Use scenarios Home audio speaker terminals: Mount to speaker cabinets or amp panels to provide a professional, lowresistance connection for speaker cables. Test equipment and lab benches: Provide repeatable, durable connection points for probes and banana plug leads during measurements and experiments. DIY electronics and custom enclosures: Integrate as a compact terminal for power or signal connections in custombuilt amplifiers, crossovers, or equipment panels. This banana socket offers a practical combination of compact size, solid materials, and straightforward installation for applications that require dependable electrical and mechanical performance.
