DELOCK DC extension cable 5.5 x 2.1 mm plug to socket with M12 x 1.75 mm screw thread waterproof 18 AWG, 1 m

DELOCK DC extension cable 5.5 x 2.1 mm plug to socket with M12 x 1.75 mm screw thread waterproof 18 AWG, 1 m is a 1-metre black DC extension cable designed to connect low-voltage devices. It features a standard 5.5 x 2.1 mm male plug and matching 5.5 x 2.1 mm female socket with an integrated M12 x 1.75 mm screw locking thread to secure the connection and provide increased protection against moisture. The cable uses 18 AWG conductors and is intended for extending power to cameras, routers, LED drivers and similar equipment for indoor or outdoor installations where a reliable, water-resistant DC link is required.

Advantages

The cable combines common 5.5 x 2.1 mm DC connectors with an M12 x 1.75 mm screw thread to reduce accidental disconnection and improve sealing at the junction. With 18 AWG conductors it supports typical low-voltage power delivery while limiting voltage drop over the 1 m length. The black outer jacket is suitable for visible and concealed installations, and the product is specified as waterproof to increase reliability in damp environments.

Suitable for

• Extending DC power to surveillance cameras and CCTV systems
• Power connections for routers, modems and network devices
• Feeding LED drivers, strip lights and low-voltage lighting fixtures
• Temporary or semi-permanent outdoor installations requiring moisture resistance

When it may not be suitable

This cable is intended for low-voltage DC applications; it is not designed for high-voltage mains use or for carrying high currents beyond what 18 AWG safely supports. For runs significantly longer than 1 metre or installations that require certified heavy-duty outdoor cabling, a thicker conductor or a purpose-built outdoor power solution may be more appropriate.

Key specifications

• Connector type: 5.5 x 2.1 mm male plug to 5.5 x 2.1 mm female socket
• Locking mechanism: M12 x 1.75 mm screw thread
• Cable length: 1 m
• Conductor size: 18 AWG
• Colour: black
• Protection: waterproof connection design

How to use

Align the 5.5 x 2.1 mm male plug with the device’s DC input and insert it fully; thread the M12 x 1.75 mm screw collar until snug to secure the connection and improve the seal against moisture. When connecting to a power supply, ensure correct polarity and that the supply voltage and current rating match the powered device. Route the cable to avoid sharp bends and protect it from mechanical damage; if used outdoors, position junctions to minimise direct exposure to water and consider additional sealing if required by the installation environment.

What to consider before purchase

• Verify that your device uses a 5.5 x 2.1 mm DC connector and the required polarity.
• Confirm that 18 AWG conductor size and 1 m length meet your voltage drop and current needs.
• Assess whether the waterproof rating and M12 screw locking are sufficient for your outdoor conditions.

Usage recommendations

For reliable operation, check polarity before powering devices, avoid overloading the conductor capacity, and tighten the M12 screw thread to maintain a secure, moisture-resistant connection. Replace the cable if the jacket or connectors show signs of wear or corrosion.
