Unknown connector (Lemo?)
(1/3) > >>
inse:
I got hold of an old FUG power supply medium voltage, 1250V, 0.5A
The high voltage output is via two circular connectors, from the look possibly Lemo brand.
The Lemo website is not really helpful for research.
Is anyone able to identify the series? Inside diameter is about 15mm and the center contact is 2.5mm.
I am not sure whether this connector is really suitable for high voltage, though there is a decent Teflon sleeve, the center contact can almost be touched with a finger…
inse:
The other question was whether I would be willing to pay for a possible Lemo counterpart or rather mount 4mm safety sockets.
Though they are only rated for 1000V - what do you think?
tggzzz:

May be worth having a look at this catalogue https://www.hivolt.de/fileadmin/hivolt/pdf/Catalog_HV_Cable_Connectors.pdf or https://www.metabee.com/blog/post/high-voltage-connectors-and-cautions-for-use

Hi inse,
 
if there is nothing on the connector (like in my photo),
then it's not a Lemo.
Maybe Fischer?

Good luck
inse:
Yes, I was already wondering because Lemo usually marks their parts.

Almost as helpful for searching as Lemo 😖 simply too many variants but thanks anyway.
What about conversion to 4mm safety connectors?
