iainmaoileoin Posted September 23, 2019 Share Posted September 23, 2019 I have various bits of (old) kit that use these connectors to get low volt DC (18-32) into equipment. Gas detectors and luggable computers. Any clues what they are called/part-numbers/how to find them. My search skills on the web just never find me the right thing Thanks Quote Link to comment Share on other sites More sharing options...
0 andym Posted September 24, 2019 Share Posted September 24, 2019 I can't see the thread but they look like standard Clansman power connectors to me. Try eBay item 123790416974 as an example, which also shows the NSN and ab connectors part number. Andy Quote Link to comment Share on other sites More sharing options...
0 iainmaoileoin Posted September 24, 2019 Author Share Posted September 24, 2019 Thanks I bought them already - thinking the same! They are male, I needed female - doh ;-( Also the pins on them are also "too far apart" so even if I got the female equivalent I would be stuck. The unit I am going into is a GID-3 Chemical detector - 1980s-1990s I would guess. Quote Link to comment Share on other sites More sharing options...
0 andym Posted September 24, 2019 Share Posted September 24, 2019 Standardisation is wonderful, isn't it? 🙂 There should be a part number on the connector, possibly on the flange inside. Andy Quote Link to comment Share on other sites More sharing options...
0 iainmaoileoin Posted September 24, 2019 Author Share Posted September 24, 2019 Been there! Tried 62GB-57A08-02PN(595). The only things I can find on the web look much more like it would plug into a hedgehog, not a 2 pin connector! I cant help feeling I have the wrong part number. Is there a good connectors site I dont know about? Quote Link to comment Share on other sites More sharing options...
0 MatchFuzee Posted September 24, 2019 Share Posted September 24, 2019 Farnell list over 100,000 circular MIL spec connectors:- https://uk.farnell.com/c/connectors/circular-connectors-components/circular-mil-spec-connectors Quote Link to comment Share on other sites More sharing options...
0 andym Posted September 24, 2019 Share Posted September 24, 2019 According to the Amphenol 62GB datasheet, 62GB-57A08-02PN(595) is a 2 pin shell size 8 jam nut receptacle with normal keyway orientation. Clansman connectors are shell size 10, hence too big. You need something like a 62GB-16F08-02SE to mate with it. A mere £48 from Farnell but they're out of stock anyway. 😞 Andy Quote Link to comment Share on other sites More sharing options...
0 iainmaoileoin Posted September 24, 2019 Author Share Posted September 24, 2019 Andym - well done and thanks, I had been trawling amphenol datasheets but only got as far as 62GB-56A08 and that did not exist. So I gave up! I will go read again, but £48 each - that is a joke for me. MactchFuzee I had been around french and uk web-sites for a while but the sheer volume of connectors (and pictures of supposed 8-2s that had 50pins and were like 25-50 just confused me). At £48 a connector I may just stay confused. Perhaps I need to open the kit up and put in a 2 pin din ;-) ta Quote Link to comment Share on other sites More sharing options...
0 andym Posted September 27, 2019 Share Posted September 27, 2019 A 2 pin DIN would be utter sacrilege - there's no worse connector in the world other than a SCART! I'd suggest replacing with a Clansman 2-pin, I've done that a couple of times when encountering weird and wonderful connectors (usually of US origin).

0 iainmaoileoin Posted September 27, 2019 Author Share Posted September 27, 2019 (edited) The 8mm JUST fits in the space between the comms connector and the base of the unit. The nut has to be aligned to the lip at the base. (The unit is a GID-3 Chemical detector). I just dont have any more mm. I may just solder up straight to the pins and then epoxy the result, sure crap but £50 for a connector is just a joke. I could leave the conector and parallel a 10mm somewhere else I guess. I have 100s of connectors - just nothing at the 08-02 size ;-( However I have read the RS site and now know abd 62GB and all the numbers and what they mean. I will keep hunting the e-pay sites in the hope something appears that is sensible in price.

0 andym Posted September 28, 2019 Share Posted September 28, 2019 Not a lot of space in there! I think as you suggest, seeing if something suitable pops up on eBay or whatever seems best. Andy Quote Link to comment Share on other sites More sharing options...
0 iainmaoileoin Posted September 28, 2019 Author Share Posted September 28, 2019 All the external connectors + the alarm switches fit in that wee "screening" box. I was hopeful I could "expand" the hole for the 8 to a 10, but that just aint going to happen ;-( The unit works OK if I fit a pin to the +ve terminal on the 08-2 and use the chassis as the ground - the resistance meters seemed to suggest that was the right way around - a dangerous testing ploy, I know. Now, I just need to find some VX/HD/HV/GB/L/GD/Chlorine and phosgene gases to test the detectors ;-) Let me not go there. Quote Link to comment Share on other sites More sharing options...
0 david1212 Posted September 29, 2019 Share Posted September 29, 2019 As a stop-gap if you can find a couple of contact sockets that fit the pins you could solder wires to them then mould around with araldite, plastic padding or similar. By coating the chassis part with silicon grease / lubricant first it will, or at least should !, not stick to the body. Then should you source a connector nothing has been damaged.

0 iainmaoileoin Posted September 30, 2019 Author Share Posted September 30, 2019 Thanks for that idea. I have my PSU connected via one pin and the crock clip on a bolt for ground, so I have pins that are OK. Silicon grease is a good idea. I had been thinking vaseline and polymorph - but was not happy getting gunge stuck in the 08-02. Polymorph is warm and might have liquified the vaseline. I will try your idea on an old wire 10-02 and report back where I get to. Quote Link to comment Share on other sites More sharing options...
0 iainmaoileoin Posted September 30, 2019 Author Share Posted September 30, 2019 David thanks for the kick. Job done. Nothing to write home to granny about, but it works. Polythene along the bottom of the plug to keep the epoxy from bonding. A cut off pen top that fits in the connector. Soldered up + and - to two pins. Fitted the pins to the plug, heat-shrunk. Used Araldite "metal" (rapid set) as the epoxy - metal does not mean conducting, just it can be shaped, drilled later. A cocktail stick pushed the epoxy into the gaps. Waited 10 mins and gingerly tried to withdraw the pen top. Results are "OK". Keeps me moving. Sure, the use of the pen-top means I have no keyways to prevent errors, but it allows me to get on an examine the rsr232 comms signals. See photos for the job and the results 1 Quote Link to comment Share on other sites More sharing options...
0 andym Posted October 1, 2019 Share Posted October 1, 2019 That should do the trick nicely! Andy Quote Link to comment Share on other sites More sharing options...
0 david1212 Posted October 6, 2019 Share Posted October 6, 2019 Looks good to me, better than I would have done. Metal loaded epoxy a good idea too as both it runs better and is more robust than Plastic Padding type fillers yet soon goes hard enough to handle. You ought to be able to form and glue a rib on to mate with the largest keyway to prevent reverse insertion. Quote Link to comment Share on other sites More sharing options...
Question
iainmaoileoin
I have various bits of (old) kit that use these connectors to get low volt DC (18-32) into equipment.
Gas detectors and luggable computers.
Any clues what they are called/part-numbers/how to find them. My search skills on the web just never find me the right thing
Thanks
