Upgrade your project's power capabilities with our 5.5mm x 2.5mm Panel Mount DC Power Jack. This heavy-duty female socket is designed for applications that require a larger 2.5mm center pin, often found in high-wattage power adapters for laptops, high-power LED arrays, and industrial chargers. With its robust threaded body and secure hex nut, this jack provides a professional, stable power input for any enclosure or control panel.
High-Wattage DIY Projects: The standard choice for projects involving high-current motors, high-power LED drivers, or battery charging stations.
Laptop Power Repair: A common replacement jack for older laptops and docking stations that use the 2.5mm pin standard.
Audio Amplifiers: Ideal for powering Class-D digital amplifiers and studio gear that demand a stable, high-current DC feed.
Industrial Equipment: Perfect for 12V–24V industrial control panels requiring a rugged, board-to-chassis power link.
Large 2.5mm Center Pin: Specifically designed for the 5.5 x 2.5mm "Type B" DC plug standard, preventing accidental use of lower-rated 2.1mm adapters.
Professional Panel Mounting: Features a threaded metal or high-impact plastic barrel with a matching hex nut for secure installation in project boxes.
Heavy-Duty Solder Lugs: Built with thick, high-conductivity terminals that can handle larger gauge wires for high-current loads without overheating.
Stable Connection: Internal high-tension leaf springs ensure a firm grip on the male plug, reducing contact resistance and preventing intermittent power loss.
High Amperage Rating: Often rated for higher current (typically up to 5A–10A depending on the model) compared to standard 2.1mm jacks.
Heat-Resistant Insulation: Constructed with UL-rated PBT or Nylon to withstand prolonged soldering and high-temperature operating environments.
Precision Fit: Ensures a "click-in" feel with matching 2.5mm male plugs for maximum electrical safety.
Connector Size: 5.5mm (Outer Diameter) x 2.5mm (Inner Pin)
Mounting Type: Panel Mount (Threaded)
Will my 2.1mm power adapter work with this?
No. While a 2.1mm plug will physically enter the 5.5mm hole, it will not make contact with the 2.5mm center pin, resulting in no power. Always match your plug and socket sizes exactly.
How do I tell the difference between 2.1mm and 2.5mm visually?
It can be difficult to see with the naked eye, but the 2.5mm pin is noticeably thicker. If your plug fits but the power is "wiggly" or intermittent, you likely have a size mismatch.
What size drill bit do I need for mounting?
Most 2.5mm panel mount jacks require an 11mm or 12mm mounting hole. Check the specific barrel diameter before drilling.
