Banana plugs, dual 4mm standard 0.75 (3/4) inch. Plugs, not sockets, plugs!

[Faranight]

Hey.

Does anyone know where to get one of those standard insulated panel-mount 4mm 3/4" banana plug assemblies? You know, the classic double banana plugs with some plastic holding them together.
Yes, I can find plenty of results for banana sockets, but I can't seem to find any equivalent double banana plugs. The opposite of what's on the picture below (with plugs instead of sockets).



Does anyone know where to get these with plugs instead of sockets?

I haven't seen a panel mount plug.

Never seen one either.

There are these types of panel mount male plugs, though. Maybe you could manufacture a shroud?

An adapter like this could maybe be mounted with the help of the binding posts:

Shops in the audio category also have a variety of banana jacks and binding posts.

Panel mount plugs are common, but the pairs, if available, are rare.   I do have little plug in boxes with paired plugs (Pomona #2098), which are now obsolete.

I got several years ago from a surplus dealer.

Out of curiosity, why do you need paired panel mounted plugs? Surely if they are going into a panel, single plugs can be individually mounted the correct distance apart (with minor errors of spacing being taken up by the compliance in the springs)?

The main advantages I can see to using paired plugs (as opposed to 2 single plugs) come with leads, preventing accidental shorting, or just a single lead being connected.

JohanH: Yes, I already have the single banana pins with a thread on the other side. Just wondering, if there is a double one available.

jpanhalt: Hmm, that's an interesting find. Probably just what I was looking for - an enclosure for a custom current shunt resistor. It's obsolete and out-of-stock though.

ralphrmartin: Yeah, I know. I already have the individual threaded banana plugs, but the problem is that the tiny enclosure I'm using is made of aluminium, so, as you've already stated, it's a no-go.
The thing with these double banana plugs is that they're held together by plastic which also insulates them from the panel. It does require you to drill a bit larger holes though.

I'm looking for something to make a DIY current sense shunt that's small enough to be plugged directly into a benchtop DMM.
Something like this (although the enclosure seems 3D-printed): https://ynformatics.com/2020/precision-30-a-current-shunt/

I suppose you could use a BNC connector on the chassis and use an adaptor on the BNC

Maybe you could use THIS part:

and use the 'cable guide hole' for mounting?
