The angle on the DIN cable doesn't have to do with the configuration of the tonearm base. Instead the issue is whether there's enough clearance between the.bottom of he tonearm base and the shelf that the turntable rests on. The DIN connector may be only an inch or two long, but you want to have enough clearance that the cable coming out of the connector doesn't crimp against the shelf as it extends from the tonearm base.

I'm planning to get one of the new Project tonearms, and they only accept 5-pin DIN connector. Is there a specific DIN connector I need to look for or are they all the same?
