DC Connector Adaptor Pack
This pack contains four new DC power adaptors that convert a 5.5mm x 2.1mm male plug to a 5.5mm x 2.5mm female socket. They suit hobbyists, installers and repairers who need to match barrel-connector sizes on CCTV cameras, routers or small electronics projects. Each adaptor is a compact passive coupler with no active electronics.
5.5 mm Barrel Conversion
The 2.1 mm centre pin on the male side mates with the 2.5 mm bore on the female side, bridging the two common barrel standards. This lets you extend or repair existing cables without soldering. The adaptor handles only the physical connection; current capacity and voltage limits remain those of the cable and power supply you attach.
Yellow Plastic Housing
Each unit measures 42 x 12.5 mm (1.65 x 0.49 in) and is moulded in yellow plastic for visibility in a parts bin. The straight barrel-to-barrel layout adds minimal bulk, so it fits inside tight enclosures or behind mounted equipment. No mounting hardware or locking mechanism is included; retention relies on the friction fit of the barrel jack.
