Works well - just want to make a note
Just a heads up, these are inside negative, outside positive (if you follow the lead length conventions). This is opposite of most things in North America. I'm glad I checked before I soldered it! It's easy enough to flip around the wires. Otherwise a great product, the plastic threads worked well for me, didn't strip like I saw in some other reviews.

    5.0 out of 5 stars Terrific Value
    Reviewed in Canada on June 4, 2021
    Verified Purchase
    I only needed two of these, to connect a DC control voltage from a PID controller to a Solid State Relay, via a double male patch-cord. These were inexpensive and now I have spares. Note that they are plastic. This has good and bad points; the good is that they are isolated from the chassis, so can be used without grounding to the metal chassis. This is sometimes needed to avoid stray currents from having multiple ground points. On the other hand, being plastic the threads could strip; that said, mine did not strip. The lugs are small and have a little hole to take a wire; they must be pre-tinned, as they took solder very readily.

    5.0 out of 5 stars Solidly made
    Reviewed in Canada on August 6, 2020
    Verified Purchase
    I feel better putting 5 (or more) amps through these connectors than the other type of commonly available chassis mount female 2.1/5.5 mm connector. These connectors use thicker gauge metal for the contacts. They also require a smaller mounting hole. The only possible disadvantage is that these guys don't have a third terminal that disconnects when a mating connector is inserted. (Like the old style earphone jack that would automatically disconnect the speaker.) But I've never needed this feature so these connectors are just fine for my purposes.

    5.0 out of 5 stars Compact and reliable
    Reviewed in the United Kingdom on April 27, 2023
    Verified Purchase
    I was needing power inlets that were compact in order to fit into a project without much depth, and these do the job well. The seem well made and soldered easily. It was necessary in my case to solder before fitting into a panel, and getting the nut over the soldered connections was then tricky, but bending the lugs slightly was possible without breakage and solved the issue.
