Can anybody identify these connectors?

Hi - I'm trying to identify these two connectors. They're off of some high voltage equipment, but one of them made me think of some connectors I've seen here so I thought I'd post it here.

The first one has written on it "Lemo Swiss FY.1.405" Lemo (http://www.lemousa.com/) seems to be the manufacturer - but for the life of me I can't find it on their website. Here are a couple blurry photos (my camera has trouble with getting close up):

The next one is the one that I thought looked like a RF connector. On it is written only Suhner. Suhner is a manufacturer of RF connectors though - which seems to confirm my suspicion. here are a couple blurry photos:

I believe this may be a Suhner SMC connector: http://www.hubersuhner.com/mozilla/p...series-smc.htm - what do you all think?

Thanks in advance!

Back to the rules section for you!

The gold one looks to be RP-SMA.


Ever consider getting a camera with a macro function?

I'm 70% sure they are not suitable for wifi as none of the models that they carry are rated for 2.4 Ghz

They could be this type

You love citing the rules don't you?

I don't think you're right about the connector type. Suhner doesn't make that kind of connector.

Awesome - I'm pretty sure that's it! I ordered up a couple that'll get here next week. Oh - and don't worry about them being suitable for wifi - they are connectors for a 1KV amplifier. I just thought since that first one is an rf connector I'd post here...

Look again AH they do make SMA connectors!

And what does a 1KV amplifier have to do with a connector being suitable for WiFi?

Do we even want to know what you're going to do with a 1KV amplifier? Or is this something we'll see either on the 6 o'clock news or the darwin awards website?

It's for some research a grad student is doing. I've already warned everybody involved about a thousand times over about the dangers of that device.

Hmm - I didn't see RP-SMA listed though - rp stands for reverse polarity I'm guessing?

And what I'm trying to say is I'm not worried whether or not the connectors are suitable for wifi - as they won't be used for such.

The first connector you might find on the trimble website. They use them on the backpack/base station GPS's. I have looked at those connectors for 6 years. Look for the RTK setups.

The second, I am not sure. But it does look like a regular cable connector. I couldn't tell from the blurry pic, but I thought I seen the center post. Maybe not.

well those Lemo connectors weren't the right part - but I now have the correct part number. The reason they couldn't be found on the lemousa website was that they aren't listed there. (they are listed on the lemo global website though). Not a single distributor has them in stock - and Lemo is quoting me 7-8 week lead time. (they're also $31.06 each - that's one spendy connector there) ARGH.

I guess I'll see what I can do about sourcing that Suhner connector - though I don't trust that thing with high voltage...

How much current you pushing through it?

It's not the current that I think he's worried about. At 1KV he's probably worried about insulation breakdown. Electricity acts 'funny' at high voltages.

If that's the case I wonder if he is worried about TRUE breakdown or just corona discharge or a single momentary flashover?

should be in the micro amps range normally. Ideally it could handle more, but it really should never even hit 1ma.

Right. I suppose it's just a single conductor connector so there shouldn't be too much to worry about - but still I'd feel better if I had that nice big Lemo connector instead...

I don't know if I'd say 1ma or less, depends.

I've seen some pretty high voltage power supplies (>2kv) that would put out well over several amps. You start messing around in the power generation industry and you get to see all kinds of interesting high power test gear and stuff.

Of course, I wouldn't be using a BNC style of connector for that.

The question becomes "what are you going to require of that power supply" when trying to replace the connectors with something that will handle the HV AND the current.
