Power Connectors

Power connectors provide the physical link between a power source and a circuit, translating wall‑adapter voltages or battery outputs into reliable feed points for boards and modules. Typical options include rectangular ATX plugs that expose multiple rails, barrel jacks that mate with standard 5.5 mm × 2.1 mm supplies, and high‑current XT60 pairs that prevent reverse polarity and hold up under heavy loads. Variants come in through‑hole, surface‑mount, and right‑angle styles, allowing straightforward routing on PCBs, breadboards or chassis. Binding posts add flexibility for banana‑plug leads or single‑wire connections, while strain‑relief features protect solder joints during vibration. Selecting the right type hinges on voltage range, current capacity, mechanical layout and the need for secure, repeatable mating.
