This 2mm short female banana socket is designed for space-constrained electronic test equipment, custom power supplies, and control panels. Unlike standard 4mm banana jacks, the 2mm variant offers a highly compact footprint, making it ideal for low-voltage signal routing, compact modular synthesizers, and miniature test jigs. The panel-mount chassis features an insulated threaded body secured by a locking nut.

Specifications

• Type: Female Jack / Socket
• Plug Diameter Compatibility: Standard 2mm banana plugs
• Length: Short profile (Typically Approx 11mm - 15mm total length)
• Mounting Thread Diameter: Aapprox 4.5mm - 5mm (Requires a matching panel cutout)
• Maximum Current Rating: 3A - 5A (Depending on ambient temperature)
• Maximum Voltage Rating: 30V AC / 60V DC (Low voltage testing applications)
• Contact Material: Nickel-plated or gold-plated brass for low contact resistance
• Insulation Material: High-temperature ABS, Nylon, or PVC housing
• Termination Method: Onboard solder tab or solder cup
• Pack Quantity: 5 pieces per pack (usually color-coded)

Features

• Ultra-Compact Profile: The shortened barrel length reduces back-panel clearance requirements, allowing the sockets to fit inside slim, low-profile project enclosures.
• Fully Insulated Body: The outer plastic shroud extends over the lip of the panel cutout, preventing electrical shorts between the live terminal wire and metal chassis plates.
• Secure Panel Attachment: Equipped with a matching hexagonal nut and optional spring lock-washer to prevent the socket from spinning or backing out when plugs are repeatedly inserted and removed.
• Reliable Signal Transmission: The nickel-plated interior spring contact maintains clean mechanical tension against matching male plugs, ensuring low contact noise in sensitive diagnostic applications.

Common Applications

• Miniature Power Supplies: Providing dedicated output rails on DIY variable bench supplies where panel real estate is limited.
• Modular Synthesizers (Eurorack/Buchla Style): Patch points for CV (Control Voltage) and audio gate signals in boutique audio gear.
• Multimeter Test Jigs: Adding quick-connect diagnostic probes to custom micro-current or battery testing rigs.
• Educational Training Boards: Assembling low-voltage physics or electronics circuit demonstration modules for labs.

Usage Tips

• Avoid Over-Tightening: The insulating plastic threads can strip if over-torqued during assembly. Tighten the hex nut until secure, but do not compress the plastic housing to the point of deformation.
• Pre-Tin the Solder Tab: Apply a small droplet of solder to the rear metal tab before attaching your wire hookup. This facilitates a faster, cleaner thermal bond and prevents excess heat from melting the nearby plastic insulation ring.
• Thermal Limitations: Keep your soldering iron contact time under 3 seconds when attaching wires to prevent the internal metal pin from shifting out of alignment due to softening plastic.
• Check Voltage Limits: These are explicitly designed for low-voltage, low-current signals. Do not use 2mm micro-sockets for mains-voltage applications (110V / 220V AC) or high-amp battery outputs, as they lack the flashover protections found on shrouded 4mm safety jacks.
