DC Barrel Plug Adapter, 2.1mm x 5.5mm Female to 1.7mm x 4.0mm Right-Angle Male, 18 AWG | RC-X1740C1
DC Barrel Plug Adapter: 2.1mm x 5.5mm Female to 1.7mm x 4.0mm Right-Angle Male
Part RC-X1740C1 connects a power supply's 2.1mm x 5.5mm male barrel plug to equipment using a 1.7mm x 4.0mm socket. Its right-angle male plug offers an alternative cable-routing direction where a straight plug may not fit. The compact pigtail uses 18 AWG wire and a 3-inch cable length, with no soldering required.
Important compatibility check: Matching connector sizes does not establish electrical compatibility. Confirm your device's required DC voltage, current, polarity, connector insertion length, and clearance before connecting. Do not assume center-positive or center-negative wiring from connector dimensions alone. Verify the adapter's wiring and polarity before use.

Applications and Replacement Guidance
Use for connector-size adaptation only after verifying the power supply, adapter, and equipment are electrically compatible. The right-angle plug may help with cable routing in confined installations; confirm physical clearance for your equipment. No specific router, camera, LED driver, or other device compatibility is claimed.
Compatibility Checklist
- Your power supply has a compatible 2.1mm x 5.5mm male barrel plug.
- Your equipment accepts a 1.7mm x 4.0mm male plug with suitable insertion length.
- The power supply's DC voltage and polarity match the equipment requirements.
- The power supply has sufficient current capacity.
- The adapter's allowable voltage and current are verified for the installation; 18 AWG alone does not establish a complete assembly rating.
- The adapter's wiring is verified, and the resulting device-end polarity is correct.
Frequently Asked Questions
Which direction does this adapter convert?
It accepts a 2.1mm x 5.5mm male power-supply plug in its female socket and provides a 1.7mm x 4.0mm right-angle male plug for the device connection.
Does it change voltage or convert AC to DC?
This is a connector conversion pigtail, not a voltage converter, regulator, or AC-to-DC power supply. Use a power source that already meets the equipment's electrical requirements.
Is this adapter center-positive?
Do not infer polarity from barrel dimensions. Verify the adapter wiring and the polarity at the device-end plug before use. A center-positive or center-negative wiring claim has not been verified for this listing.
Will it fit my router, camera, or other equipment?
Device type alone is not enough to confirm compatibility. Check voltage, current, polarity, both connector dimensions, insertion length, and right-angle clearance against the equipment documentation.
Do I need to solder the connections?
No. The adapter uses plug-in barrel connections. Verify compatibility before connecting power.
