Five-piece DC jack set

This pack contains five 2.1mm x 5.5mm female DC power socket jack connectors. They provide a straight blade plug interface for connecting power sources to compatible devices. The plastic construction includes strain relief to protect the wire termination. Each unit measures 4.4cm total length and the pack weighs 17g.

Suits low-voltage camera wiring

These adapters suit installers fitting CCTV cameras or similar low-voltage equipment that uses the 2.1mm x 5.5mm barrel standard. The female socket accepts a matching male plug from a power supply. Buyers needing a male plug, a different barrel diameter, or a screw-terminal block should look at other connector types.

Connector size is 2.1mm x 5.5mm

The critical specification is the 2.1mm inner pin diameter paired with a 5.5mm outer sleeve diameter. This exact combination must match the device power input to ensure a secure connection and correct polarity. Verify the required dimensions on the target hardware before ordering.

Questions about this item

What cable diameter must I already have to use the 2.1mm x 5.5mm female DC power socket?

The connector accepts a 2.1mm centre pin and 5.5mm outer barrel, so your existing cable must match those dimensions.

Can I connect these adapters to older equipment that uses the same 2.1mm x 5.5mm barrel size?

Yes, the 2.1mm x 5.5mm interface is a long-standing standard, so older devices with that barrel size will fit directly.

How can I confirm each of the five adapters is working after wiring them?

Apply power and verify the connected device receives voltage; the plastic strain relief should hold the cable firmly without movement.
