DC Power Connectors, Plugs & Sockets
Shop DC power connectors, plugs and sockets for electronics, low-voltage equipment, power supplies, battery-powered systems and other DC electrical applications. Our range includes DC power line plugs, barrel connectors, chassis-mount sockets, right-angle plugs and terminal-style connectors in a variety of sizes and configurations.
Common options include 2.1mm and 2.5mm DC power connectors, along with smaller DC plug sizes for compatible electronic equipment. Choose from inline and panel-mount connectors, screw-terminal and spring-terminal designs, and other DC power connection options.
When selecting a DC power connector, check the connector dimensions, plug and socket type, polarity, voltage rating and current rating. For barrel connectors, the size of the plug and socket must match correctly. A connector that looks similar may have a different internal diameter or electrical specification.
DC power connectors can be used for custom power leads, electronics projects, low-voltage equipment, battery connections, control systems and other suitable DC applications. Always check the manufacturer's specifications to confirm connector compatibility with your equipment and power source.
How to Choose a DC Power Connector
Choosing the correct DC power connector is important for ensuring a secure and compatible connection between your power supply, cable and electronic equipment. DC connectors are available in different sizes, shapes and configurations, so it is important to check the electrical and physical specifications before selecting one.
1. Check the connector size
DC barrel connectors are commonly identified by their outer diameter and inner diameter, such as 5.5 × 2.1mm or 5.5 × 2.5mm. Check the dimensions required by your equipment, as connectors that look similar may not fit correctly.
2. Choose the correct plug or socket
Determine whether you need a male DC plug or female DC socket. Options include inline cable plugs, chassis-mount sockets, panel-mount connectors and other configurations designed for different installations.
3. Confirm polarity
Check the positive and negative connections required by your equipment and power supply. Many DC barrel connections use centre-positive polarity, but this is not universal. Always confirm the polarity markings and product specifications before connecting equipment.
4. Check voltage and current ratings
Make sure the connector is rated for the voltage and current required by your application. The connector, cable and power supply must all be suitable for the electrical load. Do not assume that connectors of the same physical size have identical electrical ratings.
5. Consider the connector design
Choose a connector that suits the installation and available space. Straight DC plugs are suitable for many standard connections, while right-angle plugs can help in confined spaces. Chassis-mount sockets are useful for installing a DC connection into an enclosure or equipment panel.
6. Select the correct termination
Consider how the connector will attach to the cable. Screw-terminal and spring-terminal connectors allow wires to be connected without soldering, while other designs may require soldering or a compatible cable assembly.
7. Check compatibility with your equipment
Before purchasing, compare the connector dimensions, wiring arrangement, polarity and electrical ratings with the specifications of your equipment. Selecting a connector that matches all these requirements helps provide a reliable DC power connection.
