How do I know if I need the Male or Female 3.0mm connector?

You can identify the required connector by looking at the mating part on your device. The Male connector has visible metal pins surrounded by a plastic housing, while the Female connector has small square holes designed to receive those pins.

Why does this cable use a tinned copper core instead of bare copper?

The tinned copper core provides superior anti-corrosion properties and better electromagnetic shielding compared to bare copper. This ensures the 26AWG wire maintains high conductivity and stable performance over a longer lifespan, especially in humid environments.

Can I use these 26AWG wires for 220V AC household appliances?

No, you must never use these micro-connectors for high-voltage AC applications. They are strictly designed for low-voltage, low-current DC applications such as LED light strips, 5V sensors, or small DIY robotics.

Do I need to strip the wires before soldering them to my PCB?

No, you do not need to strip the wires yourself because they come pre-stripped from the factory. The exposed copper ends are also pre-tinned with a thin layer of solder, making them ready to attach to your PCB immediately.

Can I buy these connectors in bulk at your Hong Kong store?

Yes, you can purchase these 3.0mm 2-Pin Connector Cables in larger quantities at Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. Our physical store caters to DIY makers and schools, and our staff can assist you with finding matching PCB headers.

Full Product Description

Reliable Power Routing for DIY Electronics

The 3.0mm 2-Pin Connector Wire provides a secure, standardized power connection for low-voltage microelectronics and custom LED lighting systems. Utilizing a 3.0mm pitch and 26AWG wiring, these connectors easily interface with common PCB headers and battery terminals without forcing pins. Their compact size makes them the perfect choice for routing DC power inside tight project enclosures where standard jumper wires would take up too much space.

Premium Tinned Copper Core for Stability

This 26AWG Connector Cable features a high-purity tinned copper inner core designed to maximize electrical conductivity and minimize energy loss. The tin plating provides excellent anti-corrosion properties and electromagnetic shielding, ensuring your connected sensors or LED strips receive stable, uninterrupted power. This robust core construction guarantees a strong current load capacity for demanding low-voltage applications that run continuously.

Durable PVC Insulation and Pre-Tinned Ends

Every wire is protected by a high-density PVC wear-resistant layer that offers superior dielectric insulation and prevents accidental short circuits. To save you valuable assembly time, the wire ends come pre-stripped and pre-tinned directly from the factory. You can solder these red and black color-coded wires directly onto your custom circuit boards without needing specialized wire-stripping tools.

Selectable Male or Female Configurations

You can choose between a pack of three Male connectors or three Female connectors to perfectly match your specific project requirements. The Male variant features exposed metal pins protected by a plastic shroud, while the Female variant features the corresponding receptacles designed to snap securely into place. This flexibility allows you to build custom extension cables or replace broken terminals on both the battery side and the device side.

Pro Tip from Our Technicians

Always verify the polarity of your specific device with a multimeter before connecting these cables to a power source, as some third-party electronics reverse their PCB pinouts at the factory. If you are unsure which connector type (Male or Female) you need for your repair, bring your broken component to our Sham Shui Po store. The technical staff at Sun Cheong Computer Co. Ltd. will help you identify the correct match and provide expert soldering advice for your DIY build.
