DC Power Male Plugs 6.3mm x 3.0mm

These two straight blade plugs suit hobbyists repairing or building low voltage DC leads for small electronics and CCTV devices. Each connector accepts a 6.3 mm outer diameter and 3.0 mm inner diameter barrel jack. The PVC flame retardant housing resists heat and corrosion during soldering and long term use.

Connector size 6.3 x 3.0 mm

The critical specification is the 6.3 mm external by 3.0 mm internal barrel dimension which must match the target jack exactly. Mismatched diameters will prevent a secure fit or cause intermittent power. Verify the required size on the device or existing plug before ordering.

Thermals noise and power draw

The plugs are passive components so they generate no noise and draw no power themselves. The flame retardant PVC body withstands normal soldering temperatures without deforming. Current capacity depends entirely on the wire gauge and the connected power supply not on the connector alone.

Questions about this item

What does the 6.3mm x 3.0mm size mean when I am matching this plug to a device jack?

The 6.3mm outer diameter and 3.0mm inner diameter must match the socket exactly; a mismatch will prevent a secure connection or cause intermittent power.

Is this a standard coaxial barrel connector, and does the 6.3mm x 3.0mm dimension follow a common industry pinout?

Yes, it uses the common centre-positive coaxial barrel format; the 6.3mm x 3.0mm sizing is a widely used variant for low-voltage DC devices such as CCTV cameras and small electronics.

What do I need to fit these plugs onto a bare cable?

You need a soldering iron, solder, and heat-shrink or electrical tape; the plug housing slides over the cable before the centre pin and outer sleeve are soldered to the respective conductors.
