5.5 mm × 2.1 mm Barrel Plug Pigtail Set
This pack contains five new DC power pigtails with a 5.5 mm outer diameter and 2.1 mm inner pin barrel male connector. Each lead is 28 cm long and uses a 3.5 mm outer-diameter cable with two 0.75 mm² pure-copper conductors. The assembly is rated for 2 A continuous current and suits low-voltage monitoring or LED equipment.
Verify Connector Size and Polarity Before Buying
Measure the jack on your device to confirm it accepts a 5.5 mm by 2.1 mm barrel plug and check the centre-pin polarity required by the equipment. The pigtail provides bare leads rather than a pre-wired socket, so you must terminate or solder them to match your circuit. Ensure the 2 A rating covers the load you intend to connect.
Pure-Copper Core Handles Steady 2 A Loads
The 0.75 mm² copper conductors maintain low resistance over the 28 cm length, keeping voltage drop minimal during continuous 2 A operation. Insulation and the 3.5 mm jacket remain stable under sustained current without the overheating seen in thinner stranded leads. The fixed cable length limits reach, so plan routing for permanent installations rather than temporary test bench use.

Questions about this item
What comes in the package and do I need any extra parts to use it?
The pack contains five 28 cm pigtails, each with a 5.5 mm × 2.1 mm barrel male plug on one end and bare wires on the other. No additional components are required for a standard DC connection.
How do I pick the right version for my device?
Match the 5.5 mm outer diameter and 2.1 mm inner diameter of the plug to your equipment's DC jack; the wire gauge is 2 × 0.75 mm² and the cable is rated for 2 A continuous current.
What does the 2 A rating mean when I plug this into my LED strip?
The 2 A rating is the maximum continuous current the 0.75 mm² copper conductors can carry safely; ensure your LED load stays at or below 2 A to avoid overheating the cable.
