DELOCK DC extension cable 5.5 x 2.5 mm plug to socket with screw lock M12 x 1.75 mm thread waterproof 18 AWG 0.5 m

The DELOCK DC extension cable 5.5 x 2.5 mm plug to socket with screw lock M12 x 1.75 mm thread waterproof 18 AWG 0.5 m provides a compact, waterproof solution for extending low-voltage DC power connections. Designed for short-range power extension, the cable features a standard 5.5 x 2.5 mm barrel plug and socket combined with an M12 screw-lock thread that secures the connection against accidental disconnection and moisture. The 0.5 m length and 18 AWG conductor gauge offer a balance between flexibility and low-voltage capacity suitable for CCTV cameras, LED drivers, routers and similar devices used in indoor and outdoor environments.

Advantages

The waterproof screw-lock M12 x 1.75 mm thread increases connection reliability in environments exposed to humidity or light rain, while the standard 5.5 x 2.5 mm barrel connector ensures compatibility with many DC-powered devices. The 18 AWG conductor provides lower voltage drop over the short extension length, and the compact 0.5 m cable keeps installations tidy where only a small extension is required. The design focuses on practical durability and simple installation without tools for the barrel connection and with secure screwing for the threaded lock.

Suitable for (tasks / use cases)

• Extending power to CCTV cameras and security equipment in sheltered outdoor locations
• Connecting routers, modems or network devices requiring a 5.5 x 2.5 mm DC supply
• Powering LED drivers, lighting modules and small DC appliances where a short waterproof extension is needed
• Temporary or permanent installations in garages, porches or sheltered external junctions

When it may not be suitable

This cable is intended for low-voltage DC power at short distances and is not designed for high-current or high-voltage applications. For long cable runs or devices with higher current draw, a thicker conductor or dedicated power wiring should be used to avoid voltage drop and overheating. The waterproof rating is intended to protect against moisture and light exposure but does not substitute for full submersion-rated wiring where continuous immersion or extreme conditions are expected.

Key specifications

• Connector types: 5.5 x 2.5 mm barrel plug to 5.5 x 2.5 mm barrel socket with M12 x 1.75 mm screw-lock
• Cable length: 0.5 m
• Conductor gauge: 18 AWG
• Construction: waterproof screw-lock interface and sealed cable jacket
• Colour: black

How to use

Ensure the power source and the device are switched off before connecting. Insert the 5.5 x 2.5 mm plug into the device's DC inlet and attach the socket to the power adapter's plug. Engage the M12 x 1.75 mm screw-lock thread by turning until hand-tight to create a sealed connection; do not over-tighten. Route the cable to avoid sharp bends, pinching points and sources of heat. After installation, restore power and verify proper voltage at the device. Periodically inspect the screw connection and cable jacket for wear or damage, especially in outdoor or exposed installations.

What to consider before purchase

• Confirm the device uses a 5.5 x 2.5 mm DC barrel connector and that polarity matches the power supply
• Check that a 0.5 m extension length meets your routing and placement requirements
• Verify the 18 AWG conductor is sufficient for your device's current draw to avoid voltage drop
• Consider environmental conditions; use appropriately rated cabling for full immersion or extreme exposure

Usage recommendations

Use this cable for short waterproof DC extensions where a secure screw-lock is needed. For installations with higher currents or longer distances, plan for thicker gauge cabling and professional wiring to ensure safety and consistent power delivery.
