Construction and Materials
Moulded red-and-black plug housings (red = center conductor, black = shield return) make the reverse polarity visually obvious. Cable marked AWM 2464 80°C 300V VW-1, stranded copper cores, smooth black PVC jacket.
Typical Applications
Legacy networking gear, certain LED controllers, point-of-sale peripherals, and any DC device labelled or documented as requiring center-negative 5.5 x 2.1 mm input.
Compatibility and Fitment
Match only to equipment that explicitly calls for center-negative polarity. Standard center-positive gear can be damaged — confirm the device’s polarity marking before connecting.
Custom Builds and Ordering
Cable length, jacket colour, polarity, and connector orientation can be tailored to your build. Contact our sales team for OEM / ODM lead times, MOQ, and custom connector combinations on this DC plug power cable line. We support low-volume prototypes and high-volume production runs with consistent batch testing on every shipment, and can match the connector housing colour to your brand if requested.
Packaging and Shipping
Each DC plug power cable is bulk-packed in PE bags and shipped in export cartons. Standard packaging fits courier pallets; custom retail blister packs, header cards, and private-label boxes are available on request. Lead time for stocked items is typically 3–7 days; custom builds 2–4 weeks depending on quantity.
Quality and Compliance
Every assembly is continuity-tested and visually inspected before dispatch. Our manufacturing partners hold ISO 9001 quality systems; specific regulatory approvals (UL, CE, RoHS, REACH) for finished assemblies depend on the chosen jacket material and connector brand — please confirm requirements when requesting a quote.
