DC Extension Cable DELOCK 5.5 x 2.1 mm Plug to Socket with M12 x 1.75 mm Screw Thread, Waterproof, 18 AWG, 0.5 m, Black

DELOCK DC Extension Cable 5.5 x 2.1 mm plug to 5.5 x 2.1 mm socket with M12 x 1.75 mm screw thread provides a waterproof connection for low-voltage DC devices. The cable is 0.5 m long, uses 18 AWG conductors and is supplied in black. The integrated screw closure with M12 x 1.75 mm thread secures the plug and socket interface to prevent moisture ingress and ensure a reliable power feed in exposed or damp environments.

Advantages

This DC extension cable is made with 18 AWG conductors for adequate current carrying capacity in many low-voltage applications and features a compact 5.5 x 2.1 mm plug and socket that are widely compatible with cameras, routers, LED drivers and similar devices. The M12 x 1.75 mm screw closure delivers a water-resistant seal at the mating point, reducing the risk of intermittent connections caused by moisture. The 0.5 m length offers a short, tidy extension where minimal extra cable is required.

Suitable for

• Extending power to CCTV cameras and network cameras in sheltered outdoor locations
• Connecting routers, modems and small networking equipment that use 5.5 x 2.1 mm DC jacks
• Powering LED drivers, strips and small lighting fixtures requiring a sealed DC connection
• Temporary or permanent installations where a short, water-resistant DC extension is needed

When it may not be suitable

This cable is intended for low-voltage DC applications and is not suitable for carrying high-voltage AC power or for use where specific industrial certifications are required. The 0.5 m length is relatively short; it may not be appropriate when longer runs are necessary or when additional slack is required for routing around obstacles.

Key specifications

• Connector type: 5.5 x 2.1 mm plug to 5.5 x 2.1 mm socket
• Screw closure: M12 x 1.75 mm thread for water-resistant seal
• Cable conductor size: 18 AWG
• Length: 0.5 m
• Color: black

How to use

Align the 5.5 x 2.1 mm plug with the mating device socket and insert until fully seated. Bring the socket and plug housings together and engage the M12 x 1.75 mm screw thread to tighten the closure until a secure, water-resistant seal is achieved; do not overtighten. Route the cable to avoid sharp edges and areas of potential abrasion. Verify correct polarity and secure the power source before applying voltage to the connected device.

What to consider before purchase

• Verify that your device uses a 5.5 x 2.1 mm DC jack and that polarity matches the cable connection
• Confirm that a 0.5 m extension length is sufficient for your installation and routing needs
• Ensure the water-resistant screw closure and cable rating meet the environmental conditions of the installation

Usage recommendations

Use this cable for short extension runs where a sealed DC connection is required; inspect the screw closure periodically in outdoor or damp environments and replace the cable if the seal or conductor insulation shows signs of wear.
