Frequently Asked Questions
Q: What is the difference between a 5.5×2.1mm and a 5.5×2.5mm DC connector?
A: Both are standard barrel-style DC power connectors with a 5.5mm outer diameter, but they differ in inner pin diameter — 2.1mm vs 2.5mm. It's important to match the connector size to your device's jack. Using a mismatched size may result in a loose or non-functional connection. Check your device's specifications before ordering.
Q: What applications is this DC power connector suitable for?
A: This DC power connector is ideal for a wide variety of low-voltage applications including CCTV cameras, LED strip drivers, routers, power supply adapters, Arduino/Raspberry Pi projects, and other 24V DC electronics that use a standard 5.5mm barrel connector.
Q: Is soldering required to use this connector?
A: The connector comes pre-wired with approximately 20cm of cable, so you can use it directly by connecting the exposed wire ends to your circuit or terminal block. Soldering is optional but may be used for a more permanent installation.
Q: Is the cable long enough for most applications?
A: The included cable is approximately 20cm (about 8 inches) long, which is well-suited for panel mounting, internal wiring, or short-run connections. For longer runs, the wires can be extended by splicing additional cable.
