Female Plug

[M0ses]

This is not about basses at all. Forgive me. Talkbass is the best site for anything, ever.

I need a female version of this: 5V Adapter Not the female wall outlet, obviously. The other end.

I don't know what to search for on Mouser.

If a piece of electronics has it's power input terminals labeled positive and negative, then it matters, right? Because if not, I really could just cut off that darn circular thing and solder the wires directly to the terminals. As it is, i won't be able to tell which wire is pos or neg.

Clicky

Brilliant. Why didn't I think of searching for the dimensions? Thanks a lot.

This is direct current, so it definitely does.

You won't, but any multimeter will.

That shouldn't be necessary.

That looks like a single cable jacket, so when you strip it, you will either see a single conductor positive with a negative shield around it, or two conductors, which should be easy to identify as positive and negative.

If the cable is made up of two individually sheathed leads,the one with the ridge on the side, or a white stripe will be the negative.

It's a single cable jacket. I guessed that it would be the two conductor kind: if it is, how do you tell them apart? I have a cheapo multimeter.

Is this an analog or digital meter?

You don't want to use an analog meter, because the needle will go backwards below 0 if the polarity is reversed.

On a digital meter, it will give you a negative voltage reading when the polarity is switched.

Ok, thanks. Think I'll end up soldering it straight up and saving the cash for the connector.

If you set a higher voltage range and connect very briefly, the reverse deflection won't hurt. You'll know if the needle is moving in the right direction, even if it's just a little above/below zero.

Once you have the polarity correct, then you can select a more appropriate voltage range.
