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

[Kosmic]

So why not just dump them altogether and replace them by obtainable and affordable connectors from Lemo/Odu or whoever that fit into the hole? Not banana sockets, but push/pull connectors. Looks like the best way to go if you ask me.

That's my plan 

I will dump the old female and male connector and replace them by similar connectors I ordered from ebay.

[tggzzz]

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

Any reason for chosing the PEEK insert (-130) in preference to the PTFE insert (-60)?

Looking at the plastics' generic properties, the PTFE may have a higher voltage limit, the PEEK may have less deformation.

Hello everybody, first of all, thanks everybody for the pictures, it seems that the mounting is not as bad as I was expecting it. actually is pretty simple to unsolder and replace the connectors.
I believe one member have said that the size is M15, that means the hole is 12mm in diameter, can it be confirmed ? Because if we change the connectors, at least not drill or affect the panel.

 Now for the few forum members, is anybody else willing to call the Fischer, I'll take two connectors, one for a 2-wire lead and one for a 4-wire lead. Should we try to do a collective order ?
Or should we replace the connectors in a consistent way and invest the difference in hi-quality shielded test leads and Kelvin clips ?

Knowing my luck, after I'll change the connectors and invest in the test leads, somehow the market will be flooded with cheap or reasonably priced original test leads, if I'll keep the connectors, most likely I'll finish my reincarnation and not even see an original Solartron lead  .

But whatever the conclusion of the forum is, I will go with the crowd wisdom and do it as such, specking of which, what are some good quality shielded leads with and without Kelvin clips.

And what are the favorites for the new connectors, here I'm listing my finds as well:

And for the Teflon or other plastic type original guy, I vote to pick up the least expensive compatible one, if one of bio-Germans will give a call to Fischer, just to get a price and availability, I'll be grateful, if not I'll try to do it, but they may close the phone )

 Waiting for your opinion,

You mean you haven't even had a look inside? I may not always take it apart before turning it on, but I always get round to taking it apart! You never know what nasty surprises might be lurking inside.

As for me, I doubt I will use this instrument much, as I have lots of other DMMs (and it is rather big). Didn't even bother to look whether it works. And I do have a plug. But a colleague got the second 7061, and he did not luck out. Coming to think of it, this might well be the source of the 7061 in the OP, so he wouldn't need one.  Anyway, his mind is currently stressed with other things.

M15 should not fit in a 12-mm hole, as it's diameter is (as the name suggests) 15 millimeters.

I might be a "Bio-German", but there's one thing I just hate: Making telephone calls (which explains in part why I don't have a mobile phone).

I don't think Solartron's engineers were all wrong. The idea of needing just one connector (with excellent handling qualities) has lots of appeal. They probably hoped to set a standard with others to follow, but that didn't work out. If it did, they'd be commonplace now.

Well, about the 7061, I can offer him asylum if it's getting bored , indeed for the M15 the diameter of the hole is 13mm, for M14 nut the hole is around 12mm, but let's wait for a measure.
If aren't any takers, I'll try to call Fischer tomorrow morning.

Well, do we have the Fischer designations?
In that case I could try.

[TAMHAN]

I usually flip out most Girls due to the way I talk on the phone (they really stress out, but cant do sh#t because of = >). I also have very impressive clients so I can also try and call.

But: if this is Fischer Elektronik, we should be prepared for very high prices. They are super high quality, but very very pricey.

[picburner]

If anyone wanted to form a buy group to get a better price from Fischer I'm here.
I have a 7081 and it took me years of hunting on ebay to find only one Fischer S104A053 connector at a decent price (28 EUR).
Two other connectors would help me.

[DC1MC]

Well, do we have the Fischer designations?

Well, the consensus seem to be that the Fischer Connectors designation is:

S104-A053-130+

One member said that may be a cheaper version with 60 instead of 130 (different plastic), but if the price difference is negligible, I will go for the original.
Also, I don't know if the above designator describe a full connector, with all bits and pieces of the shell and cable bender protection, but the sales guy from Fischer should be able to produce a complete connector.

I'm one of these bio-Germans  and I'll give this morning Mr. Decker from Fischer Connectors a call.
He is the representative for the southwestern part of Germany, and that's where I'm living.

I'll go for the S104-A053-130+ since this looks to me the right thing.

Will let you know here before noon today about the results.

Thanks a lot Andreas, you really did me a favor  .

Now there are two possibilities: either the price is as unbotanium as the connector, or they will come with some old stock at an acceptable price.
I'm wondering if we should register an e.V for dealing with the suppliers, but we need at least 7 members  .

OK, I'm starting the official nails chewing until the answer arrives.

  You are welcome.

In that case I would recommend one of those wooden sticks from Starbucks. They are probably better for your teeth than the official iron nails. 
And the wooden stick comes usually with a coffee.

Ok, here we go:

I had a nice call with Fischer Connectors in Germany.

I got this prices over the phone but they want me to send them an email, which I will do right after this posting.
(I am a new customer to them so they need some details. )

I asked for 10 pieces.
Prices for the S104-A053-130+ (which is a standard connector to them):
EUR 29,- per piece

plus the additional "Kabelspannzange" which is the strain relief? cable anchorage? which is
EUR 5,- per piece

And they need the outer diameter of the cable for this.

** Edit: the diameter I gave to them was 5mm **


So, overall I think the whole plug will cost about EUR 34,- (plus shipping I think and some handling. But this will be mentioned in the written quotation, I think)

Delivery time for this plug is 3 weeks.
The plug is the shielded version.

So far from my side.

Andreas

[Kosmic]

It's cool that those connectors are still available. Nevertheless it's kind of expensive considering that I paid like 55 EUR for my 7061.

On my side I will probably stick with the cheap connectors from ebay

Let's see the final quote, I'm on the edge, sadly it will be difficult to find a home for other 8, but OK, I didn't pay 50$ on mine (sadly) and maybe some time I'll get a 7081.

 In any situation, thanks again Andreas.

I may well be interested, particularly if it can mitigate any minimum order costs.

I've sent an email to the UK part of Fischer, so I'll see what happens.

[DC1MC]

Thanks @tggzzz, I'm really interested to see which side will offer better prices, I'm tempted to call on Friday their hq in Switzerland, just to have an upper limit  .

[BU508A]

Update

I got the final quote from Fischer, please see screenshot.

plug per piece:     29,49 EUR
cable relief:            5,36 EUR

complete set:       34,85 EUR
plus VAT (19%):    6,62 EUR

total:                     41,47 EUR  (without shipping and handling)

I'm thinking about of ordering 10 sets. If there are enough people interested here, I'll do so.

[frozenfrogz]

Wow. And I always thought Lemo were chichi with their pricing...

[tggzzz]

After I get a quote from Fischer UK, I may well be interested.

[DC1MC]

Lead time 3 weeks, huh ? OK, sign me in for 2pcs. and thanks Andreas for your effort.
I hope they will came with all bits and pieces necessary.

Now I've got some chinesium Kelvin clips with shielded leads, but what to get for some nice shielded dual conductor flexible cable for the main set of 2 wire test leads ?

 Cheers,
 DC1MC

[Kosmic]

but what to get for some nice shielded dual conductor flexible cable for the main set of 2 wire test leads ?

I'm going to try this one : https://www.ebay.ca/itm/NOS-PTFE-silver-plated-cable-wire-20awg-4c-Shielded-3meter-Speaker/253173432482?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

Will use it for 2 and 4 wires test leads (as recommended in the manual).

[Kosmic]

Well the manual do not recommend this particular cable but look like they use 4 cores shielded cable for both type (2/4 leads)

[Kosmic]

Look like its possible o buy the whole cable with banana plug and fischer connector for around 200eur
