This topic its a quick presentation, of a new interesting gadget, about D-SUB Breakout Board Connector with Case.
They are two major products, DB9 & DB15.
Then they come with variations, male, female, long screws, short screws and or a plain nut.
These products they are somewhat interesting, in the applications:
Prototyping and Testing
including industrial automation, process control and data acquisition.
The product is no-name, there is nowhere any information about the cover, case, box, and operating temperature specifications.
I will classify it as nylon, -10 to +50C as Max
