I bought a 350mm for my 8x16 lathe and while I might use 370mm they barely fit with the fender fitted. They look and feel very good compared to the 100mm TOAUTO brand I bought and the standard pinout worked great with my Ditron D80-2A (Ditron seller included ribbon cable for glass scales , since my device was the default setting for Ditron magnetic scales versus glass scales). The TOAUTO unit scale had to be completely rewired, but I eventually found that the side PCB connector of the ribbon cable was essentially DB9 1-9 left to right on the PCB end connector, which was a 9-pin JST XH connector. In the first photo, the pinout of the Cozyel brand scale.
