DELOCK DC extension cable 5.5 x 2.1 mm plug to socket with M12 x 1.75 mm screw thread, waterproof, 18 AWG, 2 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, 2 m is a two-meter power extension designed to extend DC power connections reliably. It combines a standard 5.5 x 2.1 mm male plug and corresponding female socket with an M12 x 1.75 mm threaded screw closure to form a sealed, water-resistant junction. The twin-conductor 18 AWG cable provides adequate current capacity for many low-voltage DC devices and is intended for both indoor and outdoor use where a waterproof connection is required.

Advantages

The cable offers a secure mechanical connection through the M12 x 1.75 mm screw thread, reducing the risk of accidental disconnection and ingress of moisture. Using 18 AWG conductors ensures lower voltage drop over the 2 m length compared with thinner cores and supports common DC loads such as cameras, routers and LED lighting. The assembly is straightforward: the male plug mates with the female socket and the screw closure seals the interface for outdoor and damp environments.

Suitable for

• Extending power to CCTV and network cameras
• Powering routers, switches and low-voltage network equipment
• Supplying DC LED strips, spotlights and outdoor lighting
• Temporary or permanent installations that require a sealed DC connection

When it may not be suitable

This extension cable is intended for low-voltage DC applications and is not suitable for AC mains power or high-current industrial equipment. For devices that require very high current or voltages outside typical DC adapter ranges, a cable with larger conductor cross-section or different connectors is required. The waterproof seal protects against moisture but does not replace correct IP-rated enclosures for fully submerged applications.

Key specifications

• Connector A: 5.5 x 2.1 mm DC male plug
• Connector B: 5.5 x 2.1 mm DC female socket with M12 x 1.75 mm screw thread closure
• Cable type: twin conductor, 18 AWG
• Length: 2 m
• Colour: black
• Environmental protection: water-resistant sealed connector interface (not specified for continuous submersion)

How to use

Connect the 5.5 x 2.1 mm male plug to the DC output of your power adapter or source, and plug the female socket onto the device's DC input. Engage the M12 x 1.75 mm screw closure to tighten the connection and form a water-resistant seal. Route the cable to avoid sharp bends, crushing and exposure to heat sources. For outdoor installations, ensure the sealed junction faces away from direct water pooling and combine with appropriate mounting and strain relief where needed.

What to consider before purchase

• Verify that your device uses a 5.5 x 2.1 mm DC connector and that polarity matches.
• Confirm that 18 AWG conductor size is suitable for your device's current draw over a 2 m run.
• For permanent outdoor or submerged installations, check required IP rating and consider additional enclosures.

Usage recommendations

Use this DELOCK DC extension cable to extend low-voltage DC power where a sealed connection is needed. Periodically inspect the threaded closure and cable condition in outdoor settings, and avoid exposing the connector to prolonged submersion. If higher currents or specific environmental ratings are required, select a cable and connector system rated for those conditions.
