Four-piece barrel connector set

This pack contains four DC power pigtails each with a 5.5mm by 2.1mm male barrel plug. The 28cm leads suit hobbyists and technicians who need short, ready-made connections for low-voltage devices such as LED strips or CCTV cameras. Rated at 2A, they are intended for modest current loads rather than high-power distribution.

Pure copper conductors

Each cable uses a 2 by 0.75mm2 pure copper core that the supplier says gives strong electrical conductivity. The 3.5mm outer jacket protects the conductors while remaining flexible enough for tight routing inside enclosures or along mounting rails. No additional connectors, heat-shrink or tools are included in the package.

Fixed plug geometry

The 5.5mm by 2.1mm barrel size is a common standard but not universal, so the plug must match the target device exactly. Because the leads are only 28cm long, they work best where the power source sits close to the load; longer runs would require a separate extension. Builders needing right-angle plugs or locking collars will need a different product.

Questions about this item

Will the 28 cm pigtail need replacement if the 2 A rating is exceeded?

The pigtail is rated for 2 A continuous use; exceeding that limit can overheat the 0.75 mm² copper conductors and require replacement.

What limit appears first when the 5.5 × 2.1 mm barrel plug runs at full load for hours?

The 2 A current rating is the first constraint; sustained loads above 2 A will heat the 3.5 mm diameter cable beyond its design margin.

How much heat or noise does the 0.75 mm² pure copper wire produce during all-day operation?

The copper core runs silently and generates only modest warmth at the rated 2 A; no fan or active cooling is involved.
