You were lucky to catch that very rare moment it worked. I don't need those
connectors much -- have a bunch of dead sensors that I can use to build my
own calibrator and those already have the entire driving circuitry in them
so I don't have to build it from scratch. Just tried to get some to have
them in stock, just in case. I actually don't see any other use for them
except building a calibrator so not a big loss...
I just purchased 12 pcs without difficulty using a credit card for payment.

Newark became a buggy horror, I was not been able to purchase ANYTHING from
them for last 2 years or so -- there was ALWAYS an issue and their site
never worked since something like couple of years ago.
Do NOT buy anything from them, don't support the incompetence.
This is about the Amphenol Tuchel female connector discussed in this
thread's history (used by HP for panel and device mounting the 8480 series
power sensors and 43x series power meters.)
This posting (9 April 2025) probably has limited utility and will at
some point become moot, but wanted pass this along in case anyone was
interested in homebrewing HP power sensor or power meter, as the ebay
listing (offering the same connector) cited previously in the thread
disappeared some time ago.
I located stock (in US distributor Newark) a version of the female panel
connector cited in the discussion thread. They appear to be a "close out"
(from time to time, Newark reprices an item in what appears to be an
end-of-stock circumstance (the notation includes "available in quantity
shown".)
This connector is female, panel mount, with solder cup pins (12 pins.)
There are other variants of the same connector type (solder pins, etc.)
The part appears to show stock of 82 pieces (in US) at price of USD 4.12
today 9 April 2025.
Amphenol-Sine has online a data catalog which includes mechanical
drawings for this specific connector:
See page 22 for PCB layout applicable to the 12 pin thru-hole version
(PNG captured from that page is attached).
I rotated the (above) drawing of the 12 pin connector by 37.5 degrees
counter-clockwise - using powerpoint - to bring the key down to the bottom
of the connector, matching how it is used in the HP devices - and scaled it
(pins E and K are separated by 9.0 mm) so that I could use the circles
representing the 12 pins as a position guide for corresponding holes in a
PC board layout (idea is a small PCB that adapts the connector's rear pins
to a 2x4 2.54mm header for mating to a prototyping board.) Somewhat
brute-force but this was a last-minute add to a PCB layout that was headed
out for fab.
I ordered and received a couple of these connectors and they appear to
mate with the typical HP sensor cable without difficulty. The panel
mounting nut (ring) - included - would require a 2-pin hand tool to tighten.
I have a similar question as most-recent posting to this thread asked -
about whether this project got built and what the experience was!
