5.5mm x 2.1mm DC Male Jack with Wire Cable – DC Power Connector

The 5.5mm x 2.1mm DC Male Jack with Wire Cable is a practical connector for supplying DC power to electronic circuits and compatible devices. Its barrel-style plug is commonly used with matching DC power sockets found on development boards, LED lighting products, CCTV equipment, and various electronic modules.

The attached wire cable makes installation easier by providing wire leads for soldering or connecting to a suitable terminal block. It is useful for electronics technicians, hobbyists, students, and makers working on power supply connections, prototypes, and repair projects.

When selecting a DC male jack, check the connector dimensions, required voltage, current rating, and power polarity to ensure compatibility with your equipment.

Key Features

• Standard 5.5mm outer diameter and 2.1mm inner diameter DC barrel plug
• Pre-attached wire cable for convenient installation
• Suitable for compatible low-voltage DC power connections
• Useful for DIY electronics and electrical prototyping
• Commonly used with matching DC female sockets and power adapters
• Practical for repairs, testing, and custom power cables

Technical Specifications

Note: Maximum voltage, current capacity, cable length, and wire colour may vary by product batch. Confirm these details before use.

Applications and Uses

This DC male jack with wire cable is suitable for several electronic applications:

• Arduino Projects: Connect a compatible DC power source to a board or project enclosure equipped with a matching DC socket. Browse Arduino boards.
• CCTV Systems: Create or replace compatible DC power leads for cameras and related equipment.
• LED Lighting: Supply power to compatible LED strips and lighting controllers.
• DIY Electronics: Build custom power cables for electronic modules and prototype circuits.
• Repair and Maintenance: Replace damaged DC plugs on suitable low-voltage devices.
• Power Supply Connections: Connect compatible adapters to electronic equipment with a 5.5mm x 2.1mm female socket.

Installation and Connection Guide

1. Confirm that the device uses a 5.5mm x 2.1mm DC female socket.
2. Check the required DC voltage and current before selecting a power adapter.
3. Identify the positive and negative wires using the product documentation or a multimeter.
4. Connect the wires to the correct terminals, observing the device’s required polarity.
5. Insulate exposed conductors and check for short circuits before applying power.

Many barrel connectors use a centre-positive configuration, but this must not be assumed for every device.

Precautions

• Disconnect the power supply before cutting, soldering, or modifying the cable.
• Never connect the jack to mains AC voltage.
• Do not exceed the connector’s rated voltage or current.
• Verify polarity before powering your circuit; reverse polarity can damage electronic components.
• Avoid short circuits and insulate all exposed wire joints.
• Use a suitable power adapter with the correct output voltage and adequate current capacity.
• Check the inner diameter carefully, as 2.1mm and 2.5mm connectors may appear similar but are not always interchangeable.
