5.5 x 2.1 mm DC panel jack

This four-pack supplies 5.5 x 2.1 mm DC female sockets rated for 12 V and 3 A. Each unit mounts through a drilled hole in a panel or chassis and is secured with two screws. The connectors are intended for DIY audio, video and low-voltage power projects. A rubber shell and alloy-plated contacts provide durability and reliable conductivity.

Makers needing panel-mount DC input

The adapters suit hobbyists and technicians adding a fixed power inlet to enclosures, vehicle audio gear, learning notebooks or household appliances. They are not for builders who require a different pin diameter, a higher current rating or a connector without a panel-mount footprint. The integrated waterproof cap protects the socket when not in use.

5.5 x 2.1 mm centre pin size

The critical specification is the 5.5 mm barrel and 2.1 mm centre pin, identified as the 5521 form factor. Only plugs matching these dimensions will make a secure connection. Verify the plug size on your power supply or device before purchasing.

Questions about this item

How much heat does the 12 V 3 A DC jack generate when it runs all day?

The socket is rated for 12 V at 3 A with a high-quality alloy contact and rubber shell that resists high temperature, so normal continuous use stays within its thermal design.

What panel thickness and hole size do I need to mount the 5.5 x 2.1 mm socket?

Drill a hole in the base panel, then secure the socket with two screws; the kit includes the waterproof cap and mounting hardware for a standard panel cut-out.

Will the 5521 connector fit the barrel plug on my older 12 V audio gear?

Yes, the 5.5 mm outer and 2.1 mm inner dimensions match the common 5521 barrel standard used on many legacy audio, video and appliance power supplies.
