I recently got a used Data Precision 8200 voltage/current standard. It uses the attached connector for its 100mV output. Is there a name for this type of connector? Where can I buy a male plug that will connect to it properly?
The diameter of the inner black plastic part is about 16mm and that of the outter metal threaded part is 20mm.

Pretty sure that's just a locking DIN connector. Mouser, DigiKey, and the like have them in almost infinite variations of pin count and arrangements.

In the service manual it says its a 3 terminal shielded connector. I think it is a DIN as rexxar said.

Thank you! I'll look into these more.

Make sure to get gold plated pins on whatever connector you get with such a low signal level. 100mV typically wont be enough to help break though an oxide layer if the connector doesnt have good wiping action when you mate it.

This connector is actually a microphone connector. It is an Amphenol 91-PC3F. The mating connector is 91-MC3M. I've attached the datasheet. These are now obsolete. I found one on Ebay (NOS) and bought it. Be warned, though, that since these are used on microphones (both ham and professional), the audiophiles create a demand which runs the prices up. I also found several people making cables with the other end being an XLR connector. Hope this helps.
Gold plated pins were never an option. The contacts seem to be somewhat of a tuning fork with high pressure. I would not expect a problem.
