Reduction coupling Lightwin DC 12/7MM Red – DC power connector 12mm to 7mm

Lightwin Reduction Coupling DC 12/7MM Red adapts a 12 mm DC power plug to a 7 mm DC jack. The compact, lightweight coupling provides a secure mechanical and electrical connection between different-sized DC connectors and is intended for low-voltage equipment. It is compatible with power supplies, routers, CCTV cameras and other devices that require conversion from a 12 mm plug to a 7 mm socket.

Advantages

The DC 12/7MM Red coupling enables quick size conversion without modifying cables or power adapters. Its compact design saves space and simplifies cable management. The part offers a straightforward and reversible solution for adapting 12 mm DC plugs to 7 mm DC jacks while maintaining electrical continuity.

Suitable for

• Power supplies and external adapters that use 12 mm plugs
• Routers and network devices with 7 mm DC input
• CCTV cameras and surveillance equipment
• Temporary repairs, testing and troubleshooting of DC connections

Key specifications

• Brand: Lightwin
• Model / MPN: DC 12/7MM RED
• Function: Reduction coupling / adapter from 12 mm plug to 7 mm jack
• Color: Red
• Application: Low-voltage DC connections (power adapters, routers, CCTV)

How to use

Insert the 12 mm DC plug into the larger end of the coupling until it seats firmly, then connect the smaller 7 mm end to the device's DC jack. Verify that the connection is secure and that polarity matches before powering the device. No tools are required for installation; the adapter can be removed by pulling it off the connectors.

Usage recommendations

Use the coupling only for compatible low-voltage DC equipment and ensure correct polarity and voltage match to prevent damage. Do not expose the adapter to moisture or excessive mechanical stress. For permanent installations, consider using a dedicated cable or connector of the correct size.
