Source note: Every value is taken from the SUYEEGO DD20048 datasheet, which also supplies the feature bullets apart from the mounting details, which come from the supplied mounting-structure graphic. The datasheet states no certification or warranty terms, so none are shown, and it does not say which dimension is which — the three figures are printed here in the order the source gives them.
