Each plug measures 45 mm long with a maximum diameter of 10 mm and accepts cable up to 5 mm thick. The housing combines plastic and metal with a black and silver-tone finish, and the set weighs 17 g in total.

Questions about this item

What DC voltage and current does the 5.5 mm x 2.1 mm barrel interface on these plugs support?

The 5.5 mm x 2.1 mm barrel is a common low-voltage DC standard; the plug housing itself does not set a voltage or current limit — that is determined by the power supply and cable you attach.

What are the overall length and maximum diameter of each plug, and what cable diameter does the strain relief accept?

Each plug measures 45 mm long with a maximum diameter of 10 mm, and the strain relief is sized for cables up to 5 mm in diameter.

How do you assemble the plug onto a cable, and which step is most often done incorrectly?

Slide the housing onto the cable first, strip the conductors, solder the centre pin to positive and the outer sleeve to negative, then screw the housing on — the step most often missed is threading the housing onto the cable before soldering.
