Wire-end ferrules, DIN 46228 (end sleeves): length, collar diameter and colour code, 0.5 to 50 mm², French and German colours — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/wire-end-ferrules-din-46228/ (sheet CC BY 4.0) Basis: GAM catalogue table (one length per size), checked against Weidmüller H10,0/22D, Otto Fischer and Klauke data sheets; colour codes from stex24, cross-checked with Phoenix Contact; no CAD files Catalog version: 2026-10-20 Sizes: see table below - 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). - Uninsulated DIN 46228-1 sleeves (GLW catalogue): 1.5 and 2.5 mm² in lengths l = 7, 8, 10, 12, 15*, 18, 20* mm (* not to the standard), d1 1.7 and 2.2 mm, wall s 0.15 mm; the d1 and s values match the insulated rows. The GLW copy's d2 column did not align cleanly, so it is not used. - Rows marked # (FTR1-8#, FTR1.5-8#): the maker's footnote says the insulated ones are DIN 46228-4 'except #'; the page does not say what differs. AWG pairings are the maker's (a 1 mm² sleeve is listed against 18 AWG). - Left out: files (the sleeve bore / outside-diameter ambiguity above), crimp-die codes, other makers' length steps.
