The tonearm connector isn't a DIN, nor is it even a JIS. It is something which appears to have been designed as a tonearm-specific electrical connector. I believe that the company that designed it was called Denon Parts (no relation to the other more famous Denon).
You can find real DIN connectors and connectors used on products by Naim Audio, DNM, and probably others. If you look into these brands, you may find some reasons for why they prefer DINs over RCAs.
