DELOCK DC extension cable 5.5 x 2.1 mm plug to jack with bayonet lock, 18 AWG, 0.5 m, black

DELOCK DC extension cable 5.5 x 2.1 mm plug to jack with bayonet lock, 18 AWG, 0.5 m, black is a short, robust extension lead designed to extend the reach of low-voltage DC power connections. The cable pairs a 5.5 x 2.1 mm coaxial plug with a matching jack that features a bayonet locking mechanism to prevent accidental disconnection. With an 18 AWG conductor and a length of 0.5 m, the cable provides a balance of current capacity and flexibility for common devices such as routers, CCTV cameras and LED drivers.

Advantages

The bayonet lock secures the connection against vibration and accidental pull-out, improving reliability in fixed installations. The 18 AWG conductor supports stable current flow for many low-voltage appliances while the compact 0.5 m length reduces excess cable bulk in confined spaces. The black jacket offers a discreet appearance suitable for both consumer and professional environments.

Suitable for

• Extending power to routers, modems and network equipment
• Power connection for CCTV and IP cameras that use 5.5 x 2.1 mm DC plugs
• Connecting LED drivers, small monitors and other low-voltage electronics
• Temporary or semi-permanent installations where a locked DC connection is preferred

When it may not be suitable

This cable is intended for low-voltage DC applications and is not suitable for mains voltage or high-power devices that require thicker conductors or specialized connectors. If your device requires a different coaxial size, higher current rating or a longer reach than 0.5 m, this product will not meet those requirements.

Key specifications

• Connector type: 5.5 x 2.1 mm coaxial plug to jack with bayonet lock
• Conductor size: 18 AWG
• Length: 0.5 m
• Cable colour: black
• Contact orientation: coaxial DC (centre pin and barrel conductor)

How to use

Align the plug with the jack and push the coaxial plug into the socket, then rotate or engage the bayonet mechanism according to the connector design until it locks in place. Verify the connection is secure by applying gentle tension; the bayonet lock should prevent unplugging. Use the cable to extend the power lead between a power adapter and the device. Route the cable to avoid sharp bends or strain at the connectors and secure it where necessary to prevent tugging.

What to consider before purchase

• Confirm your device uses a 5.5 x 2.1 mm DC coaxial connector and that a bayonet lock is compatible with the device jack
• Ensure 0.5 m length is sufficient for your installation or plan for additional extensions
• Check the current requirements of your device to verify that 18 AWG conductor capacity is adequate
• Not suitable for AC mains or high-power equipment

Usage recommendations

For stable operation, avoid routing the cable near heat sources or sharp edges, and secure the cable to reduce mechanical stress on the bayonet connection. Periodically inspect the connector for debris or wear that could affect contact quality.
