I found the CP-7340-ND. Please review for your needs!
Thank you for your fast reply, and for the part number PDP-40 (mfr. CUI Devices, DigiKey p/n CP-7340-ND).
I also received a different response from Robert Fay who said the mating male connector is the KPPX-4P (mfr. Kycon Inc., DigiKey p/n 2092-KPPX-4P-ND).
They both look very similar, but to be on the safe side, I will order a couple of each model. At least one of them should work.
Thank you again for your kind help.
