Power adapter DC Dongle ProXtend DCDONGLE-7450-6037-AS 7.4mm to 6.0mm DC barrel connector adapter

ProXtend DC Dongle DCDONGLE-7450-6037-AS is a compact passive adapter that converts a 7.4 mm DC barrel plug to a 6.0 mm DC barrel plug. It enables direct mechanical compatibility between power supplies and devices with differing barrel jack diameters without altering electrical polarity or voltage. The adapter is intended for applications where a simple physical size conversion is required for laptops, routers and other consumer electronics.

Advantages

The adapter offers a straightforward and reliable mechanical conversion that preserves the original electrical connection. Its small form factor requires minimal space and adds negligible weight to a cable assembly. Because it is a passive barrel-to-barrel adapter, there are no active components that could affect voltage regulation or introduce failure points. The adapter is suitable for intermittent use or as a practical field solution when the correct plug size is not available.

Suitable for

• Converting a 7.4 mm DC barrel plug to fit a 6.0 mm DC jack
• Temporary or emergency power connections for laptops and notebooks
• Connecting power adapters to routers, switches and small network appliances
• Field service, repairs and testing where plug size mismatch occurs

Key specifications

• Connector conversion: 7.4 mm (male) to 6.0 mm (female) DC barrel
• Type: passive mechanical barrel adapter
• Typical use: low-voltage DC power interconnection (no voltage conversion)
• Material: conductive metal contacts with insulating body (manufacturer typical materials)
• Form factor: compact inline dongle, lightweight

How to use

To use the DC Dongle, insert the 7.4 mm plug of the power supply into the adapter's 7.4 mm end, then insert the adapter's 6.0 mm end into the device's DC jack. Ensure the connection is fully seated to maintain proper contact. Verify that the power supply voltage and polarity match the device requirements before powering on. Because the adapter is passive, it will not change voltage, current rating, or polarity—confirm electrical compatibility to prevent damage.

Usage recommendations

Use this adapter only when the voltage, current capability and polarity of the power source are already compatible with the device. Avoid using the adapter in high-vibration or exposed outdoor environments without additional strain relief or weather protection. Inspect contacts for wear or corrosion periodically and replace the adapter if any damage or poor contact is observed.
