How it sits against the LD75P2-CM and LD75D4-CM
Versus the sibling LD75P2-CM, also 2 axes, the LD75D2-CM runs 4M pulses/s at 10m distance versus 200K pulses/s at 2m. If your application needs high speed or longer cable runs, the D2 is the one. The LD75D4-CM adds two more axes but shares the same 4M pulse speed and 10m distance—so if you need 4 axes, step up to that; but it won't drop into a 2-axis wiring plan without additional cables.
