I recently found this part on ebay categorized under PLC parts.
I haven’t found any similar images on the web and haven’t found it by the part number.
And what is that silver part?
No parts/contacts on the other side.
After some days of research, I now think this is from a medical device (MRI/MRT/CT) like the Magnetom or Phantom series due to K2025 / K2115 on other parts.
The K2025 is part of the Model No, on the other side is a bar code and another number starting with S01, what is a serial No.
I first thought this might be from a mainframe, or a washing machine. There are thousands of parts for all kind of machines.
During research, I found these Simens product lines, most are PLC based, but the most relevant is the SIMATIC line S3/S5/S7. I only found 3 on Wikipedia, maybe there are even more
