15-piece screw-in DC jack kit

This pack contains fifteen female DC power jack sockets sized at 5.5mm by 2.1mm. Each unit has a three-pin layout with two active contacts and a third pin for mounting stability. The screw-thread barrel lets you secure the jack to a panel or enclosure. They are suited for automotive accessory wiring and general low-voltage board work.

Solder-ready pins and panel threading

The pins accept solder for direct PCB or breadboard attachment. A threaded collar allows the jack to be fixed through a chassis cut-out without extra hardware. The metal and plastic construction resists vibration in vehicle environments. The mixed silver, black and grey finish helps identify polarity during assembly.

Simple panel mount with basic tools

Drill a hole matching the 11mm ring diameter, insert the jack and tighten the threaded collar by hand or with a spanner. Solder the two active pins to your circuit; the third pin only adds mechanical support. Misaligned holes or over-tightening can crack the plastic insulator. Builders needing a different barrel size or pin count must source another part.

Questions about this item

Will the 3-pin solder joints on these 5.5x2.1 mm jacks need rework after repeated plug cycles?

The two active pins carry the electrical connection while the third pin provides mechanical stability; normal mating cycles should not fatigue the solder joints if the board pads are properly sized.

What stops me from tightening the 11 mm threaded ring beyond the panel thickness?

The 18 x 14 mm body length and 11 mm ring diameter limit how far the jack can protrude; once the threads bottom out against the panel, further torque risks cracking the plastic insulator.

Do the metal shells and plastic insulators get hot when the connector runs at its rated current all day?

The metal housing and plastic body dissipate the small contact resistance of a 5.5x2.1 mm barrel jack; under continuous rated load the parts stay warm but not hot enough to degrade the insulator.
