DC Power Jack Socket Kit

This pack contains five 5.5 x 2.1 mm threaded female panel-mount sockets with pre-attached 20 cm 18 AWG pigtails. Each cable uses 41 strands of 0.16 mm brass tin-plated copper per conductor, giving 82 strands total across the red and black leads. The zinc-alloy housings are nickel-plated for conductivity and oxidation resistance. Dust caps, washers and nuts are included for a complete panel installation.

DIY Installers and CCTV Integrators

The kit suits anyone adding low-voltage DC power to an enclosure, security camera or custom project where a secure threaded connection is required. Builders needing a different barrel size such as 2.5 mm, or those who require longer leads without splicing, should look at other options. The 11 mm mounting hole diameter must match the panel cut-out.

Check Panel Thickness and Polarity

Verify that your enclosure material allows an 11 mm clearance hole and that the panel thickness accommodates the supplied nut and washer stack. Confirm the power supply polarity matches the red-positive and black-negative colour coding before soldering or crimping. Ensure the 18 AWG gauge meets the current demand of the connected device.

Questions about this item

What size panel cut-out do I need for the 11 mm threaded barrel on these sockets?

Drill an 11 mm hole; the threaded 5.5 x 2.1 mm barrel fits through and secures with the supplied nut and washer.

Will the 18 AWG pigtails handle the same current as the 22 AWG leads on my existing CCTV power supply?

Each 18 AWG lead uses 41 strands of 0.16 mm brass tin-plated copper — 82 strands total per cable — so it carries more current with less voltage drop than typical 22 AWG pigtails.

How can I confirm the polarity is correct once the red and black leads are soldered to my board?

The red lead is the positive centre-contact and the black lead is the negative barrel; measure continuity from the centre pin to the red wire and from the barrel to the black wire to verify.
