   "Wire-end ferrules (end sleeves, bootlace ferrules, Aderendhülsen) are crimped on the stripped end of a stranded wire so a screw or spring clamp does not splay the strands. DIN 46228 part 1 is the plain (uninsulated) sleeve, part 4 the sleeve with a plastic collar. The table is one maker's catalogue (GAM, 'insulated to DIN 46228 part 4, except #' rows): one length per cross-section plus the twin (two-wire) sleeves. Lengths come in several steps per size, so L1 / L2 / D1 / D2 change with the length you pick.",
   "Column meanings as Weidmüller labels them on its H10,0/22D sheet: L1 overall length, L2 length of the metal sleeve, D1 'contact surface diameter', D2 collar diameter, S1 metal wall, S2 plastic collar wall. The Weidmüller 10 mm² sleeve (L1 22, L2 12, D1 4.5, D2 7.6, S1 0.2, S2 0.4) matches the GAM row exactly. Otto Fischer's 1 mm² DIN 46228-4 sleeve is the same type in a longer step: l1 18, l2 12, d1 1.4, d2 3, s1 0.15, s2 0.25 (the GAM row is the 14 / 8 step: D1 1.4 agrees, D2 is 3.4 vs 3.0). Klauke's 0.75 mm² grey sleeve: L 16, pin length 10 (DIN 46228/4). Neither sheet says whether D1 is a bore or an outside diameter, so no solid is drawn.",
   "Colour codes by cross-section: the DIN 46228-4 / German / French columns come from stex24's table and agree with Phoenix Contact's colour table (DIN 46228-4, UL 486-F, NF C 63-023 and a special German code) for every size from 0.5 to 50 mm². Colour alone does not identify the size (DIN grey is both 0.75 and 4 mm²; red is 1, 10 and 35 mm²). Outside the standard: 0.14 mm² grey, 0.25 light blue, 0.34 turquoise (DIN-style practice); 70 mm² yellow, 95 mm² red, 120 mm² blue (DIN 46628 as stex24 lists it).",
