The unobtanium connector of Solartron 7061, what to do, please help ?

[DC1MC]

Hello, I may get a Solartron 7061, but I wasn't able to find any suitable testleads or even connector for the beast, both for front and back  .
Any ideas ?

 Cheers,
 DC1MC

Pictures ?

Maybe this guy can hook you up.

Holly mother of crappy crap 

And the Farnell website is down

Looking at the data sheet and at the previous mentioned blog, indeed the connector has an voltage isolation of about 320V, how in the world was supposed to measure 1000V ?!?!?

Also the right type seem to be: Fischer Connectors S 104A053-130+

 Did anybody actually have seen such a Solartron probe, did I miss something, is it an active probe or has an embedded divider ?

 Vielen Dank @frozenfrogs, it's really painful to get one of these probes, I'm wondering what happend wit them.

 Cheers,

Maybe the other way around is deemed to be less painful...
There has to be some option to retrofit a decent - still in active production - connector.

Can't you swap out the socket on the meter for something more common?

This guy, Ian, made a post here on getting a connector for a 7075, didn't get any joy so decided to replace the DIN connector with bananas:

Hi Gerry, thanks for the tip, I've seen the thread and Jan was thinking and considering to install bananas, drilling, vibrating and masacrating the cables will most likely completely destroy the little calibration and stabilization that the device have , so I keep this option as plan N.

It is a thread about something similar indeed, but little does help me to get a connector or the Fata Morgana probe  .

Sure I can, there is nothing easier than drilling holes, but to do this I should either disassemble the beast or vibrate it with the drill, nothing that will increase the health, stability or exactness  of the old timer.
I'll still fight for a suitable connector, I was able to find one for the other ridiculous crap that my EFRATOM Rubidium oscillator has, one it will appear for this guy as well, I hope  .

ok if you say so    from that thread I got a cross reference on google to a Chinese supplier in that pdf I found that its generic name is a 'Pull-push F Series Connector'

cross ref the specs of the fischer and the other manufactures to get the connector you need first google result brings up lemo

Thanks Bob, for your continued effort, I'm getting blind with age,  because I didn't see this reference to the Chinese site, my 7061 will arrive in ca. two weeks, so there is a bit of time for exploring.
I did a look at the Lemo guys, but wasn't able to understand if there is a compatible model.
Anyway, If someone finds a (compatible) connector that can be used without modifying the device connector, it has guaranteed a pair of beers form me, if also finds somewhere a working probe at an acceptable price, a double pair of beers will wait him/her .

From the thread I linked to come up with

Fischer - SC 104 A 053, 104 series

googled without the spaces SC104A053

that led me to http://www.anovaypart.com/goods-108679-SC104A053+-130.html

And this data sheet http://www.anovaypart.com/datasheet/connector/Pull-push%20F%20Series%20connectors.pdf

SC104A053 crosses to ANPP0127841

Using the generic name brings up lemo

[DC1MC]

The sad story it that actually none of this sites has a stock, a price, or a way to buy a few , just "put here your email and will eventually send you a quote"

I think that the best hope is Lemo, but still wasn't able to get the equivalent, if any 

 DC1MC

[GerryBags]

You could try making one? A cylinder of insulating material (nylon, teflon?) that will fit inside an existing existing plug that will donate its case (something of similar size, obv, XLR?). you can get the inserts in strips, solder the wires from your cable on and use epoxy to insulate the joins from each other. You could the fit the whole thing into your case. I still think that removing the front panel entirely, fitting your new terminals and then reinstalling it would be the way to go. I fail to see how that would affect the cal in any way. 

[BravoV]

If you could find Lemo's equivalent part number, and then try Aliexpress, got mine the "fake" one which I think pretty decent and for sure its damn cheap compared to genuine Lemo. 

Here are the comparisons of fake vs genuine, I won't tell which one (left or right). 

[bob225]

Mouser stock Lemo not exactly cheap, Hirose may also do a equivalent

[DC1MC]

Sure I can try and succeed to make what the Germans here call a "pfuscherei", that is some kind of pathetic improvisation, and while it will probably do make some numbers on the display, I think I will not be able to call this dmm not even close a 7 1/2 digits, not to mention that I don't have quality contacts and the HV resistance/capacitance of those plastics + epoxy is totally unknown ( I did see a glorious explosion  of a main connector filled with epoxy, it was a very nice and "glass like" dual component resin, looking at it would have thought that is at least 10KV/mm  ).

Tho only ones that seem to be the originals, I have found on fleabay, of course, you get a ridiculous connector at a ridiculous price and ridiculous  shipping to have a trifecta , but at least seem to be  the real thing:

Still waiting for the knight in shiny armor to provide us an equivalent at a human price

BravoV, at this moment, looking at the prices and materials and tools that I have, a Chinese fake will be better and more affordable then whatever I could produce.

Farnell is back up so.................

SC 104 A 053 - https://www.farnell.com/datasheets/1320348.pdf

Find the lemo part an you will find the Chinese special

[DC1MC]

I'm looking at it Bob, but I didn't find yet this specific layout of the pins anywhere , Farnell seem to not carry the originals anymore, the ANOVAY Chinese replicators seem to have been banned everywhere except India and China, and I don't see anything with this layout, depressing.

Yet another source for rich (US) people:

https://ecommerce.keiconn.com/s-104-a053-130.html

Edit, to crush others hopes and spare some effort:

 - LEMO: No such arrangement of the pins, case closed

 - Hirose: No such arrangement of the pins, case closed

 - ITT Cannon: No such arrangement of the pins, case closed

 - NorComp: No such arrangement of the pins, case closed

 - Amphenol-Alden: No such arrangement of the pins, case closed

 - Souriau: No such arrangement of the pins, case closed

 So except if someone proves me wrong with the above, finds some new old stock or some Chinese clones, I will have to destroy the instrument and improvise some sockets, to not have thrown away almost 400 EUR.
The original ultra-expensive ones ones are nice, but more suitable for a 7071/7081 where the price and performance make it worth paying the super-extra premium with EU shipping and customs on top.

Of course if you find something, all hints are welcome and the beers are permanently available, but now I'm taking ideas about what to replace with these infernal sockets  .

I got the same problem. Just got a Solartron 7061 but can't find the connector.

So I'm planning to replace the probe connector by this one: https://www.ebay.ca/itm/1Set-8mm-9mm-10mm-12mm-XLR-Aviation-Panel-Chassis-Metal-Quick-Fast-Connector/321605780222?ssPageName=STRK%3AMEBIDX%3AIT&var=510491955786&_trksid=p2060353.m2749.l2649

I figured it was easier and less destructive than drilling 5 holes for some banana plug connector.

Still waiting for the connector from ebay thought.
