DC Power Adapter 5.5mm x 2.5mm Female to 5.5mm x

This adapter converts a 5.5mm x 2.5mm female jack to a 5.5mm x 2.1mm male plug for DC power connections. It is intended for CCTV camera power supply links and similar low-voltage devices. The body measures 40mm long by 12mm diameter with a black, blue and silver finish.

Installers matching a 2.5mm centre pin to a 2.1mm

Technicians who need to bridge the 0.4mm difference between these two common barrel sizes will find this part useful. It is not for buyers who require a 5.5mm x 2.5mm male plug or a 5.5mm x 2.1mm female jack. The single-unit pack also suits one-off repairs rather than volume jobs.

Connector type 5.5mm x 2.5mm Female to 5.5mm x

The decisive specification is the gender and pin diameter on each end: a 5.5mm outer sleeve with a 2.5mm centre hole on one side and a 5.5mm outer sleeve with a 2.1mm centre pin on the other. Confirm both dimensions on your equipment before ordering.

Questions about this item

Should I choose the 5.5mm x 2.5mm female to 5.5mm x 2.1mm male version or a different size?

Choose this version when your power supply has a 5.5mm x 2.5mm jack and your CCTV camera needs a 5.5mm x 2.1mm plug; the 2.5mm centre pin on the female side accepts the supply while the 2.1mm centre pin on the male side fits the camera.

What does the 40mm length mean once the connector is installed?

The 40mm overall length adds roughly 1.57 inches between the power supply and the camera cable, keeping the joint compact inside a CCTV housing.

Is the 5.5mm x 2.5mm to 5.5mm x 2.1mm interface a standard barrel type and what does it limit?

Yes, it uses the common 5.5mm outer diameter barrel standard; the 2.5mm to 2.1mm centre-pin change adapts the connection without altering voltage or current handling.
