Problem & Solution
Flimsy power wiring and loose DC plugs are a constant source of frustration in custom electronics projects. Unsecured wires poked through rough enclosure holes often bend, short-circuit, or tug out unexpectedly, putting your sensitive components and power supplies at risk.
This 5-pair 12V DC male and female barrel connector set solves that problem by giving you a clean, industrial-grade power port interface. The female sockets feature dedicated lock nuts and threading to mount flush against your project casing, providing a neat exterior jack that locks your internal power supply down safely.
Matching male plugs ensure a snug, snap-fit connection that resists accidental dislodging. Whether you are building custom LED controllers, repairing CCTV systems, or housing micro-controller projects, this set turns messy wiring into a professional, plug-and-play setup.
