Need assistance with 37 pin connector and contact pins

Hello,
I am looking for assistance locating the connector and extra pins. I am newer to identifying these connectors and trying to get the correct pins. The info stamped on the connectors are not bringing up any info nor do I find results when looking at circular connectors to have anything match.

The writing on the 37 pin connector:
MC 16/250
E3-36 PE/S

The pin sizes, in MM are below:
Overall Length – 33.25mm
Pin tip Diameter - ~1.5mm
Pin end that solders to wire – 2mm



Hello splitxserenade,

I see a few connectors with the same pin arrangement. Click here for those options.
But I did not find anything that looked like your connector, without a thread or bayonet section, to fasten it to the mating connectors. We would need to identify the connector, to find the pins that are associated to it.
