## Summary description

4mm banana connector plug designed for electrical test and measurement applications. Rated for 30A continuous current and up to 60V DC, it provides a compact single-pole connection for probes, leads, or panel sockets. Useful for laboratory work, bench testing, repair tasks and prototyping where a reliable, high-current miniature connector is required.

## Long description

The 4mm Banana Connector Plug is a single-pole test connector intended for electrical test and measurement applications. It provides a compact connection for probes, leads, or panel sockets, supporting continuous currents up to 30A and direct voltages up to 60V DC. The plug's 4mm diameter mating surface is compatible with standard banana jacks and sockets used in laboratory benches, test equipment, repair work and prototyping.
Advantages
The connector offers a combination of high current capacity in a small footprint and straightforward mechanical mating with standard banana sockets. Its single-pole design simplifies wiring and probe setup while maintaining consistent electrical contact under typical bench and field conditions. The rated parameters ensure suitability for many low-voltage, high-current measurement and connection tasks without requiring larger, bulkier connectors.
Suitable for
Laboratory test leads and instrumentation connections
Bench testing of power supplies, batteries and DC circuits
Repair and maintenance work on electronic equipment
Prototyping and temporary wiring in development setups
Key specifications
Contact diameter: 4 mm
Current rating: 30 A continuous
Voltage rating: up to 60 V DC
Polarity: single-pole
Typical applications: test and measurement, bench connections, lead terminations
How to use
Insert the 4mm plug into a compatible banana jack or socket until it seats firmly, ensuring a secure electrical and mechanical connection. Use appropriate insulated leads and observe polarity when connecting to measurement instruments or power sources. For panel or fixed installations, fit the plug into the matching socket and verify contact integrity before applying load. When disconnecting, grip the insulated body of the plug rather than pulling on the cable to avoid damaging the connection or conductor.
Usage recommendations
Use the connector within its rated limits: do not exceed 30 A continuous current or 60 V DC. Choose appropriately rated wires and leads for the current, and inspect contacts periodically for wear, oxidation or contamination to maintain reliable measurements and connections.
