DELOCK DC extension cable 5.5 x 2.1 mm plug to socket with bayonet lock, 18 AWG, 2 m, black

DELOCK DC extension cable 5.5 x 2.1 mm plug to socket with bayonet lock, 18 AWG, 2 m, black is a purpose-built cable for extending low-voltage DC connections. The cable features a 5.5 x 2.1 mm barrel plug and matching socket with a bayonet locking mechanism, an 18 AWG conductor for reliable current carrying, and a 2 metre flexible black jacket suitable for indoor and sheltered outdoor installations. It is designed to maintain a stable power connection for devices such as routers, CCTV cameras, LED drivers and other low-voltage equipment that use the common 5.5 x 2.1 mm DC connector.

Advantages

The bayonet lock secures the plug to the socket and reduces the risk of accidental disconnection during vibration or movement. The 18 AWG conductor provides lower resistance compared with thinner wires, improving voltage stability over the 2 m span. The flexible black jacket offers mechanical protection and ease of routing in installations where a neat, concealed cable run is required.

Suitable for

• Extending power to routers and network equipment using 5.5 x 2.1 mm DC connectors
• Powering CCTV and surveillance cameras where a secure connection is needed
• Connecting LED drivers, small monitors and point-of-sale devices with compatible DC barrels
• Temporary or semi-permanent indoor installations and sheltered outdoor setups

When it may not be suitable

This cable is intended for low-voltage DC applications using a 5.5 x 2.1 mm plug/socket and is not suitable for mains AC power or devices requiring higher voltages or specialized connectors. It is not intended for fully exposed outdoor use without additional protection against weather and UV exposure.

Key specifications

• Connector type: 5.5 x 2.1 mm barrel plug to matching socket with bayonet lock
• Conductor size: 18 AWG
• Cable length: 2 m
• Colour: black
• Usage: low-voltage DC power extension

How to use

Ensure the device and power source are powered off before connecting. Insert the 5.5 x 2.1 mm plug into the device or power adapter corresponding socket, then engage the bayonet lock by twisting or pushing according to the connector design until it seats securely. Route the cable to avoid sharp edges and excessive bending; leave service loops where necessary. To disconnect, release the bayonet locking mechanism before pulling the plug free.

What to consider before purchase

• Confirm your device uses a 5.5 x 2.1 mm DC connector and that polarity matches
• Verify that 2 m length and 18 AWG conductor meet your voltage drop and routing requirements
• Consider environmental exposure—provide additional protection for fully outdoor installations

Usage recommendations

For reliable performance, use the cable within the intended low-voltage range of your equipment, avoid running alongside high-voltage AC cables to reduce interference, and check the connection periodically to ensure the bayonet lock remains engaged and free of corrosion or debris.
