   "D2F: body 12.8 (±0.15) × 5.8 (±0.15) × 6.5 (±0.1) mm and the two Ø2.0 (+0.12 / 0) mounting holes come from the leocom copy of the data sheet, whose own extraction warns that drawing labels are hard to read; the 'W × H × D' header (12.8 × 6.5 × 5.8) fixes the order. A mounting-hole spacing of 12.7 mm appeared in that read but was not confirmed as a hole-centre spacing, so it is not used. The OnlineComponents copy states 'use M2 screws together with washers' and terminals on a '2-pitch (2 × 2.54 mm)' spacing. General tolerance ±0.4 mm unless otherwise stated.",

   "V-15: two reads agree on the #187 quick-connect terminal (t = 0.5, tolerance +0.13 / −0.03 as printed) and on a Ø3.1 mounting hole; the V-15G sheet says the K models have Ø2.9. The numbers 22.2 ± 0.1, 27.8, 37.8 ± 0.8 and 10.3 ± 0.1 appear in the outline drawings, but their labels (hole spacing or body width) were lost in both extractions, so none is assigned here.
