5.5mm x 2.1mm DC Female Power Jack with Wire Cable

Pre-wired DC female socket cable

This DC female power jack provides a socket and attached wire leads for a suitable low-voltage DC connection. The listed 5.5mm x 2.1mm size identifies the compatible barrel-plug format.

It can be considered for a project power input, replacement socket connection or suitable extension assembly. Uses such as CCTV equipment, LED lighting or electronics projects still require the correct electrical and mechanical match.

Check the connector fit

Use a compatible male barrel plug and confirm its size, engagement length and contact fit. A 5.5mm plug with a different centre size should not be assumed interchangeable, even if it appears to fit loosely.

For the mating connector, see the 5.5mm x 2.1mm DC male jack cable. Matching product names alone do not establish the current rating or suitability of a complete assembly.

Verify polarity and power requirements

Check which wire connects to the centre and outer contacts using suitable test equipment. Do not assume centre-positive wiring from the connector type or lead colours. The source voltage, polarity and load requirements must match the equipment.

Cable length, wire gauge, maximum current and voltage limits are not specified here. Confirm those details before selecting a load. Insulate exposed connections, provide appropriate strain relief and make connections with power disconnected.

This cable is not a voltage regulator or power supply and is not intended for direct AC mains wiring. Browse connectors and cables at EPRO for other options.
