DC extension cable DELOCK 5.5 x 2.1 mm plug to jack with bayonet lock, 18 AWG, 1 m, black

DELOCK DC extension cable 5.5 x 2.1 mm plug to jack with bayonet lock, 18 AWG, 1 m, black extends low-voltage DC power connections between adapters and devices. The cable uses a single‑core 18 AWG conductor and standard 5.5 x 2.1 mm barrel connectors to transmit power to routers, CCTV cameras, LED drivers and similar equipment. A bayonet locking mechanism on the plug provides a secure mechanical connection that resists accidental unplugging during installation or movement.

Advantages

The cable combines a common barrel connector size with an 18 AWG conductor to maintain reliable current delivery over a 1 m length while keeping flexibility for routing. The bayonet lock adds mechanical security and helps ensure uninterrupted power to connected DC devices. The black sheath offers a neutral appearance suitable for professional and domestic environments.

Suitable for

• Extending power from DC adapters to routers, modems and network equipment
• Powering CCTV cameras and other surveillance devices at short distances
• Connecting LED drivers, strip lights or low‑voltage lighting fixtures
• Temporary or fixed installations where accidental disconnection must be minimised

When it may not be suitable

This 1 m cable is intended for short‑range DC power extension; it may not be appropriate for installations requiring longer runs. For applications demanding higher current capacity or very low voltage drop over distance, a thicker conductor or different gauge cable may be required.

Key specifications

• Connector type: 5.5 x 2.1 mm male (plug) to female (jack)
• Locking mechanism: bayonet lock on plug
• Conductor: single‑core, 18 AWG
• Length: 1 metre
• Colour: black
• Usage: low‑voltage DC power transmission

How to use

Align the 5.5 x 2.1 mm plug with the corresponding jack on the device or power adapter, push the plug in and rotate or engage the bayonet mechanism until it locks. To disconnect, release the bayonet latch according to the connector design and pull the plug straight out. Route the cable to avoid sharp bends and pinch points, and secure it to prevent strain on the connectors. Verify polarity and voltage compatibility between the power source and the device before making the connection.

What to consider before purchase

• Confirm the device uses a 5.5 x 2.1 mm barrel connector and matching polarity
• Check that 1 m length is sufficient for your installation needs
• Ensure the 18 AWG conductor meets the current requirements of your device
• Decide whether a bayonet locking plug is required for mechanical security

Usage recommendations

For reliable operation, use this cable only with compatible DC adapters and devices, avoid running it alongside high‑voltage power lines, and inspect connections periodically to ensure the bayonet lock remains engaged and free of debris.
