Shop 2.5mm DC barrel connectors for low-voltage power wiring, cable repair, custom leads, and equipment hookups. This collection includes 2.5mm DC barrel plugs, 2.5mm DC barrel jacks, inline connectors, panel mount jacks, bulkhead feed-through jacks, solder-type connectors, solderless screw terminal versions, barrel adapters, and extension cables. These parts are commonly used anywhere a 5.5mm x 2.5mm DC power connector is needed for dependable DC power connections.

5.5mm x 2.5mm DC Power Connectors for Repairs, Power Distribution, and Bench Work

5.5 x 2.5mm DC barrel plugs and jacks are commonly used for low-voltage electronics, test equipment, bench power setups, enclosures, and general DC wiring. Inline connectors are useful for replacing worn or damaged cable ends, while panel mount and bulkhead DC jacks are better for projects that need a fixed connection point on a box or chassis. This category also includes extension cables and adapter styles that help simplify power connections without rebuilding an entire cable.

Inline, Panel Mount, Bulkhead, Solder-Type, and Screw Terminal Options

This collection includes multiple connector formats for different installation needs. You will find inline DC plugs and jacks for cable assembly, panel mount jacks for permanent installations, bulkhead feed-through jacks for pass-through mounting, traditional solder-type connectors for secure permanent wiring, and solderless screw terminal DC connectors for faster field connections without soldering. That mix makes it easier to choose the right connector style for the actual job instead of forcing a workaround.

How to Choose the Right 2.5mm DC Barrel Connector

Start by confirming whether you need a plug, a jack, a panel mount connector, an adapter, or a complete extension cable. Then match the connector style to the installation. A standard inline connector works well for cable repair and custom leads. A panel mount or bulkhead jack is the better choice when you need a secure mounting point on an enclosure. If you are connecting between different barrel sizes, a 2.5mm to 2.1mm barrel adapter may be the simplest solution.

Adapters and Extension Cables for 2.5mm DC Power Connections

Along with loose connectors, this category includes practical cable and adapter options such as 2.5mm DC extension cables and barrel size adapters for matching existing power supplies and equipment. These are useful when you need to extend a power run, adapt between connector sizes, or complete a repair without replacing an entire power lead.
