Metal 2.1mm DC Female Panel Mount Jack
The metal 2.1mm DC female power jack is a reliable solution for connecting DC power sources in LED lighting projects, surveillance systems, or DIY electronic applications. Its all-metal construction ensures superior conductivity and significantly greater durability compared to plastic variants. It is panel-mounted on enclosures, cases, or distribution boards, providing a stable and secure connection point.
What you get with this product
- Stable and uninterrupted DC connection — the metal body eliminates the risk of deformation or cracking over time, common with plastic jacks
- Universal compatibility with 2.1mm male plugs — standard used on most adapters, LED power supplies, and controllers
- Simple panel mounting — the external thread and included hexagonal nut allow quick fixing in 12mm holes without special tools
- Complete kit in the box — connector, tightening nut, and locking ring included, ready for immediate installation
- Solder lug terminals — facilitate direct wire connection by soldering, with no additional clamps needed
- High mechanical resistance — galvanized metal casing with nickel finish resists vibrations, repeated coupling loads, and dusty environments
How it works and how to install it
The jack is inserted through the front of the panel into a 12mm hole, then the hexagonal nut is tightened from the back to rigidly secure the connector to the surface. The power wires are soldered to the two lug terminals on the back of the jack — the center terminal for the positive pole and the outer terminal for ground. Once installed, it accepts any standard 2.1mm DC male plug, ensuring direct and stable electrical contact with each coupling.
