DC extension cable DELOCK 5.5 x 2.5 mm plug to socket with M12 x 1.75 mm threaded screw waterproof 18 AWG 2 m

DELOCK DC extension cable 5.5 x 2.5 mm plug to socket with M12 x 1.75 mm threaded screw, 18 AWG, 2 m is a waterproof power extension designed to deliver low-voltage DC reliably between devices. It combines a common 5.5 x 2.5 mm barrel connector interface with a matching socket that secures by an M12 x 1.75 mm threaded screw coupling. The cable length of 2 metres and 18 AWG conductors provide a balance between flexibility and current-carrying capability for many small electronic installations in indoor and outdoor environments.

Advantages

The cable provides a sealed connection thanks to the M12 x 1.75 mm threaded screw, reducing the risk of water ingress and accidental disconnection. Using 18 AWG conductors supports stable low-voltage power transmission with reduced voltage drop over the 2 m length. Compatibility with standard 5.5 x 2.5 mm DC jack and plug formats makes it suitable for a wide range of cameras, routers, LED lighting and similar devices. The cable’s robust construction and screw-coupled waterproof interface are intended to extend device placement options where a reliable, weather-resistant power link is required.

Suitable for

• Extending DC power to surveillance cameras and CCTV systems
• Powering outdoor or semi-exposed LED lighting fixtures
• Connecting routers, switches or network devices that use 5.5 x 2.5 mm DC plugs
• Temporary or permanent installations where a waterproof DC connection is needed

When it may not be suitable

This cable is intended for low-voltage DC applications and is not suitable for AC mains power or high-voltage systems. Devices that require higher current than the safe carrying capacity of 18 AWG over the specified length may experience voltage drop or heat build-up; consult device specifications to confirm compatibility. The threaded M12 coupling provides water resistance but does not guarantee submersion-proof performance unless explicitly rated for the installation conditions.

Key specifications

• Connector pair: 5.5 x 2.5 mm DC plug to matching 5.5 x 2.5 mm socket with M12 x 1.75 mm threaded screw coupling
• Cable conductor size: 18 AWG
• Length: 2 metres
• Function: DC power extension for low-voltage devices
• Environmental protection: screw-coupled waterproof interface for improved ingress resistance
• Colour: black

How to use

Ensure both devices are powered off before connecting. Align the 5.5 x 2.5 mm plug with the device inlet and insert fully, then engage the matching socket and rotate the M12 x 1.75 mm threaded screw coupling until hand-tight to form the sealed connection. Route the 2 m cable to avoid sharp bends and mechanical strain; secure with cable ties or clips as needed. After installation, power on the source and verify stable voltage at the receiving device. Periodically inspect the threaded coupling and cable for wear or damage, especially in outdoor installations.

What to consider before purchase

• Confirm device connector size is 5.5 x 2.5 mm and polarity matches the cable usage
• Verify the device’s current draw is suitable for 18 AWG conductors over a 2 m run
• Determine whether the waterproof rating meets your exposure conditions (splash-resistant vs. submersion)
• Check required cable length and routing constraints for your installation site

Usage recommendations

Use this DELOCK DC extension cable to extend power to low-voltage devices in locations where a sealed connection is beneficial. For outdoor or damp environments, tighten the M12 threaded coupling and apply appropriate strain relief. Avoid routing the cable near high-voltage lines or heat sources, and replace the cable if insulation or connectors show signs of deterioration.
