What this cable does

This is a 1.2 metre DC power extension cord with a 4.0 mm by 1.7 mm male barrel plug on one end and stripped, tinned leads on the other. It is built for CCTV cameras, DVRs and similar low-voltage devices that use this exact connector size. The cord includes a ferrite magnetic ring to suppress high-frequency interference on the power line.

Connector fit is the deciding factor

The plug has a 4.0 mm outer diameter and a 1.7 mm inner diameter, so it only fits female jacks with those precise dimensions. Verify the device socket before ordering because a mismatched barrel will not connect and no adapter is included.

Thermals noise and power draw

The cable is rated for 2 A continuous current and uses a 2.0 mm diameter PVC jacket with pure copper conductors. In normal operation it runs cool, adds no audible noise and the magnetic ring reduces conducted EMI without affecting voltage delivery.

Questions about this item

What does the 2 A current rating mean once the cable is connected to a device?

It indicates the cable can safely carry up to 2 A of DC current, so the connected equipment must draw no more than that to avoid overheating the conductors.

What does the 4.0 mm × 1.7 mm male barrel plug cap in practice?

It mates only with a matching 4.0 mm outer and 1.7 mm inner diameter female jack, limiting use to devices that specify exactly that barrel size.

What physical clearance does the 1.2 m length and 2.0 mm outer diameter require for routing?

The cord needs a 1.2 m reach from the power source to the device and enough space to accommodate a 2.0 mm thick cable along its path.
