I'm pretty sure it is *not* (compatible with) a Lemo connector: The "Sealectro" has anNo worries. I think your assessment is indeed correct, I don't think it's even
worth trying, so LEMO model 303 is not compatible with Sealectro 950-0019-86,
I've canceled the order.
The biggest problem is that, in the current catalog from Sealectro, it doesn't
even have a 950 prefix, it seems the series has been permanently discontinued
and there is no information about substitute. I went to Q-service's website as
suggested by Bruce as well, but it requires dedication to find the part in the
huge listings, not to mention the multi-week international shipping.
Now I decide to replace the power cord with a generic one with a DIN connector.
The power cord is not a impedance-controlled coax, replacing it should be straightforward,
getting a shielded cord should work well.
Meanwhile, if anyone has ideas about potentially compatible parts, I would
purchase and test them. I think it may help someone else in the future, my
thread seems to be the only discussion about the 3-pin power connector I
can find on the entire web.
