DC Barrel Plug Adapter, 2.1mm x 5.5mm Female to 3.0mm x 6.3mm Male, 18 AWG | RC-X63

DC Barrel Plug Adapter: 2.1mm x 5.5mm Female to 3.0mm x 6.3mm Male

WARNING: CONNECTOR-SIZE ADAPTER ONLY, NOT A VOLTAGE CONVERTER.

Matching connector sizes does not establish electrical compatibility. Confirm DC voltage, current requirements, adapter ratings, and polarity before connecting equipment. This adapter does not regulate voltage or convert AC to DC. Incorrect voltage or polarity can damage equipment.

Part RC-X63 accepts a power supply's 2.1mm x 5.5mm male barrel plug in its female socket and provides a straight male barrel plug listed as 3.0mm inside diameter x 6.3mm outside diameter. It uses 18 AWG wire and a 3-inch cable for plug-in connector adaptation without cutting or soldering.

Intended Use

Use to adapt the connector size of an otherwise compatible DC power supply to equipment accepting the specified male barrel plug. Confirm insertion length and clearance as well as both diameters. No specific device compatibility is claimed.

VERIFY CONNECTOR DIMENSIONS AND OUTPUT POLARITY

The current product description and dimension diagram specify a 3.0mm inside diameter; the packaging photo labels it 3.1mm. Verify the required fit by measurement or supplier documentation before relying on an exact match. Do not infer wiring or resulting polarity from connector dimensions alone. Confirm the adapter's wiring and measure device-end voltage and polarity before connecting equipment.

Compatibility Checklist

• The power supply provides the equipment's required DC voltage, not AC output.
• The supply has sufficient current capacity for the equipment.
• The power-supply plug fits the 2.1mm x 5.5mm female socket.
• The equipment connection matches the male plug's measured inside and outside diameters, insertion length, and clearance.
• The adapter assembly's allowable voltage and current are verified; 18 AWG alone does not establish a complete assembly rating.
• The adapter wiring and measured device-end polarity match the equipment requirements.
• Power is disconnected before connecting or removing the adapter.
