Common Applications for DC Power Cables

LED Strip Lighting

DC power cables are essential for LED strip installations. Our 5.5×2.1mm and 5.5×2.5mm cables connect LED drivers to strips, available in various lengths for residential and commercial lighting projects.

CCTV Cameras & Security Systems

Security cameras commonly use DC barrel connectors for power. Our right-angle cables are perfect for dome cameras and tight installations. Extension cables available for long-distance runs.

Routers & Networking Equipment

Many routers, switches, and modems use 5.5×2.1mm or smaller barrel connectors. Custom length cables help organize networking racks and eliminate excess cable clutter.

Industrial Control Panels

Industrial equipment often requires custom DC power connections. We manufacture cables with specific lengths, gauges, and terminations for PLCs, sensors, and control systems.

Frequently Asked Questions About DC Power Cables

P. What is the difference between 5.5x2.1mm and 5.5x2.5mm DC connectors?
A. Both have the same outer diameter (5.5mm), but the inner pin diameter differs: 2.1mm vs 2.5mm. They are not interchangeable - using the wrong size can cause poor contact or damage. Check your device's required size before ordering. Many devices have the size printed near the power port.
P. What wire gauge (AWG) do I need for my DC power cable?
A. Wire gauge depends on current (amps) and cable length. As a general guide: 22AWG supports up to 2A, 20AWG up to 3A, 18AWG up to 5A, and 16AWG up to 10A. For longer runs, you may need thicker wire to prevent voltage drop. Contact us with your requirements and we'll recommend the appropriate gauge.
P. Do you offer right-angle DC power cables?
A. Yes, we manufacture right-angle (90-degree) DC power cables in all standard sizes. These are ideal for tight spaces, wall-mounted devices, and installations where a straight plug would protrude too far. Available in up, down, left, and right orientations.
P. What is the maximum length for DC power cables?
A. Maximum practical length depends on voltage and current. For 12V/1A applications, lengths up to 10m are possible with proper wire gauge. For higher currents, shorter lengths are recommended to minimize voltage drop. We can calculate the optimal gauge for your specific length requirements.
P. Can you make DC extension cables (male to female)?
A. Yes, we manufacture male to female DC extension cables in all standard sizes. These allow you to extend the reach of your existing power supply. Custom lengths available.
P. What is the MOQ for custom DC power cables?
A. Standard MOQ is 1000 pieces per design. For startups and small projects, we offer low MOQ options - please contact us to discuss your specific needs.
P. Can I get a sample before mass production?
A. Yes, samples are available within 7-10 days. Sample costs are typically deducted from your mass production order. Custom samples based on your specifications are also available.
P. Do you offer DC power cables with bare wire ends?
A. Yes, we offer DC plug to bare wire (stripped and tinned) cables. This is popular for custom installations, connecting to terminal blocks, or DIY projects. Wire colors are typically red (positive) and black (negative).
P. What certifications do your DC power cables have?
A. Our standard DC cables are CE, RoHS, and REACH compliant. UL certification is available upon request for specific applications and volumes.
P. Can you match a specific color for my DC cable?
A. Absolutely. We offer Pantone color matching for cable jackets and connector housings. Send us your brand colors and we'll match them exactly.
