 1. Product Introduction

4mm Male to Male Banana Plug is a common electronic test connection line with standard 4mm banana plugs on both ends for quick and reliable connection of test equipment (such as multimeters, power supplies, oscilloscopes, electronic loads, etc.). Banana plugs are widely used in laboratories, electronic repairs and education because of their easy insertion and stable contact.

2. Advantages
Quick connection: easy plugging and unplugging, saving time.
Low contact resistance: high-quality metal (copper plated with gold/nickel) ensures good conductivity.
Strong compatibility: suitable for most 4mm banana sockets (such as multimeters, power supplies, etc.).
High durability: elastic metal sheet or spiral design ensures long-term stable connection.
Safe insulation: outer plastic or rubber sheath prevents accidental short circuit.

3. Application scenarios
- Electronic testing: connect multimeters, oscilloscopes, signal generators, etc.
- Power connection: used for laboratory power supply, battery testing, electronic loads, etc.
- Teaching experiments: Provide convenient connections in physics and electronic engineering experiments.
- Audio equipment: Some amplifiers and speakers use banana plugs to connect speakers.
 

 

Product Specifications

Parameter Item	Specification
Interface Type	4mm male to male banana plug
Plug Material	Copper gold-plated/nickel (good conductivity, anti-oxidation)
Insulation Material	PVC/rubber (high temperature resistance, anti-short circuit)
Shell material	Silicone
Maximum Current	Usually 5A~30A (depending on the model)
Maximum Voltage	Usually 30V~600V (depending on the insulation level)
Cable Length	Commonly 30cm/50cm/1m/2m (optional)
Application Field	Electronic testing, laboratory, audio connection, etc.

1. Purchase suggestions
Material selection: Prefer copper-plated or nickel-plated plugs to reduce oxidation and improve conductivity.
Length selection: Select the appropriate length according to the use requirements (common 30cm/50cm/1m).
Insulation performance: Ensure that the outer insulation material is resistant to high temperatures and short circuits.

2. Precautions for safe use
Avoid high-voltage applications: Ordinary banana plugs are usually suitable for low voltages (<30V), and special insulation models must be selected for high voltages.
Prevent short circuits: Make sure the device is powered off when plugging and unplugging, and avoid metal parts touching other conductors.
Regular inspection: Check whether the plug is oxidized or loose after long-term use, which affects conductivity.
Correct plugging and unplugging: Insert the socket vertically to avoid lateral force that may cause deformation of the plug.

3. FAQ
Q1: Can banana plugs be used for high current applications?
A: Yes, but you need to choose a high current model (such as 10A or above) and ensure that the plug and the socket are in good contact.

Q2: Is the 4mm banana plug universal?
A: Basically universal, but some special devices (such as some audio interfaces) may have different specifications, and you need to confirm the match.

Q3: How to clean the plug after oxidation?
A: You can wipe it with alcohol or lightly polish it with fine sandpaper to restore conductivity.

Q4: Can it be used for alternating current (AC) and direct current (DC)?
A: Yes, but you need to ensure that the voltage and current are within the rated range of the plug.

4. Summary
4mm Male to Male Banana Plug is a commonly used connection line for electronic testing and laboratories, with the advantages of fast plugging and unplugging, low resistance, and high compatibility. When purchasing, you need to pay attention to the material, insulation performance and current carrying capacity to ensure a safe and reliable use experience.

Humanity Design

High-quality flame-retardant materials: polymer materials have the advantages of flame retardancy and high temperature resistance; phosphor bronze gold-plated/tin-plated, with the advantages of wear resistance and corrosion resistance. High-tech anti-oxidation technology: improve the anti-oxidation and anti-corrosion capabilities, and maintain the characteristics of the metal surface.

Using thickened oxygen free copper wire core effectively reduces resistance and makes the circuit less prone to overheating. Simultaneously coated with a fireproof layer, it remains safe and durable even in high-temperature and dry environments. Bold thread body, sturdy and resistant to bending, will not break after long-term use.

Application

- Electronic testing: connect multimeters, oscilloscopes, signal generators, etc.
- Power connection: used for laboratory power supply, battery testing, electronic loads, etc.
- Teaching experiments: Provide convenient connections in physics and electronic engineering experiments.
- Audio equipment: Some amplifiers and speakers use banana plugs to connect speakers.
