Help with pin connector identification

[Streeter8]

Hello - I have been trying to track down this connector someone gave me years ago. The diameter of the 4 prongs together is approx. 0.085". There are a few threads that the plastic cover uses to tighten up.

This looks like a typical 2 mm banana plug (2mm equals approx. 0,085''). These come in various forms.

Agree on banana plugs.
Here are images from google images.

Do y’all happen to know the name of the specific style? I’ve ordered the mini 2mm bananas but they do not fit well for the application I use them for.

Has your device got ‘female’ banana sockets?

Too loose? You can open them up a little by spreading the blades out. Quite common for older jacks.

I use them for testing with proximitors. They have test ports (circled in thumbnail) so the permanent wiring doesn’t need to be removed. The leaves on the mini plugs tend to break off when removing them and the body is much wider than the tip so they knock together and cause my connect to drop out.

Ah ok. That unit doesn’t look like it has banana sockets.
Did your original wire and plug come with it from new?.
I would think somebody on here can tell you what connectors/jacks your unit requires.

No, they don’t officially make any testers for them. I’ve ordered some different parts to see if I can get something else to work.

Bootlace ferrules?

Do they lock in and pressing the plastic lever above, unlock them?
The ferrules that @Kiwi mentioned might well work better than banana plugs.

Martin - the levers are for releasing the permanent wires. The test ports have a tension piece near the bottom that holds the pin in place but nothing locks it in.

I’m going to order a few of the piece Kiwi shared. That looks promising!

Good idea, they’re not expensive.
You could always add your own connector type if you don’t mind opening the unit and changing them? Or hardwire to inside and have external connections?. Just another idea.
