Female DC Power Socket Jack Prewired
The Female DC Power Socket Jack Prewired is a convenient and ready-to-use DC connector designed for quick and secure low-voltage power connections in a wide range of DIY electronics, CCTV systems, LED lighting, and small appliances. This socket comes prewired with insulated leads, eliminating the need for soldering or crimping, and making it ideal for rapid installation or repairs. It features a standard barrel-style female DC socket, compatible with common 2.1mm or 2.5mm male DC plugs, depending on the version.
The robust molded housing ensures a stable connection while the pre-attached wires offer flexibility in connecting directly to power circuits, terminal blocks, or screw terminals. This connector is especially popular among hobbyists and installers for prototyping and plug-and-play DC power setups.
