Product Description

Product Description

Wire Harness

This DC male to female power connector cable is designed for stable low-voltage transmission in LED, CCTV and electronic equipment.
The cable uses stranded oxygen-free copper conductors and a flexible PVC jacket to ensure reliable power delivery while maintaining good bend performance. Nickel-plated copper terminals inside the barrel connectors provide low contact resistance and improved corrosion resistance, helping reduce power loss and extending product life.

Both ends adopt standard 5.5×2.1 mm DC barrel interfaces, widely used in adapters, LED strip drivers, security cameras, routers, audio equipment and other electronic devices. The male plug connects easily to a power adapter, while the female jack works as an extension interface, making wiring more flexible in cabinets, ceilings or confined spaces.

We support OEM/ODM services, including custom cable length, wire gauge, jacket color, labeling and packaging, to match different project and branding requirements.
