DC Power Jack Connector 5.5 x 2.1 mm Socket DC050
= Standard Panel-Mount or PCB Power Input Connector for DIY Electronics and Equipment =
The DC050 is a standard DC power jack featuring a 5.5mm outer diameter and a 2.1mm inner diameter barrel, widely used in industrial equipment and DIY electronics projects. It is designed for a reliable, secure connection to a standard DC power adapter .
Standardised 5.5mm x 2.1mm Barrel - The most common size for powering development boards and routers, ensuring broad compatibility .
SMD or ThroughHole Options Available for both surfacemount and panelmount (often with 3-pin) installation, providing design flexibility .
Mating Plug: Designed for standard DC plugs with a 5.5mm outer and 2.1mm inner pin .
Typical Current Rating: Up to 4A for most models .
Use for Arduino, breadboard power supplies, and peripheral device connections.
Check your power supply's tip size; mixing 2.1mm (DC050) and 2.5mm (DC052) plugs can cause poor contact .
