I'm planning to use this power adapter which says its connector is 5.5 x 2.1 x 12mm DC jack.

I need to find its panel mount counterpart to install in an enclosure, but there are many types of DC sockets where some are female some are male. I cannot conclude the exact type of the connector from the datasheet of this adapter so I cannot figure out a counterpart.

Would this work as counterpart?

Which parameter(s) should I look at?

  • \$\begingroup\$ No, the power supply has a 2.1mm centre hole, and the counter part you linked has a 2.5 mm pin (right at the bottom of the page, specificartions). Look for one with a 2.1mm pin. \$\endgroup\$

  • \$\begingroup\$ @Neil_UK Thanks for the feedback. I checked for 2.1mm but for sockets theres only 2mm ones. Like this uk.rs-online.com/web/p/dc-power-connectors/8782628 There's no 2.1mm inner diameter socket for some reason. \$\endgroup\$

  • \$\begingroup\$ I got it 2mm pin is fine for 2.1mm diameter \$\endgroup\$

  • \$\begingroup\$ IME these connectors are already de-facto standardized; you just need the right one; if you find something labelled as 5.5/2.1 (or 2.1/5.5) barrel jack, it'll be the right one. Then you can choose one that's panel mount and whatever you need. \$\endgroup\$

The easiest way to find a manufacturer/type number of a matching socket, as there are so many, is going to one of the larger component sellers like Mouser or DigiKey and do a search for "power connectors" yielding this, for example. Check visually if the results contain what you are looking for.

Then filter on what you know (inside diameter, outside diameter, panel-mount, current, depth, etc.), to find what you need, like so, for example.

This should give you a list of type numbers to use for your shopping.

I'm not sure the links I included are persistent or session-bound, but you get the idea.
