Article0906-3-15-20-75-14-11-0 · 0.5 µm gold over nickel · through-hole
Stroke0.7 mm working, 1.4 mm to solid — the working stroke is the tolerance a joint may stack; at solid the pin stops being a spring
Working height4.81 mm nominal, 4.11 mm at solid, 5.51 mm free
Force0.245 N preload → 0.588 N at working stroke, per contact
Electrical2 A continuous, 3 A peak · 20 mΩ
EnvelopeØ1.5 mm sleeve · Ø1.07 mm plunger · 5.51 mm free length
Board footprintØ1.83 mm pad over a Ø0.51 mm minimum hole — what the pin lands in, not what it mates against
Materialscopper alloy sleeve and plunger · beryllium copper spring
Cycle life1,000,000 mating cycles
Geometry authority: manufacturer-drawing
Datum: Board top face at z = 0; pin axis +Z; tail modelled below the board.
Exact selected Mill-Max 0906-3-15-20-75-14-11-0 article: catalog free length, sleeve/plunger/shoulder/tail diameters, mounting hole and pad, spring-75 strokes and forces, materials, current, contact resistance and cycle life. Mass is the distributor’s. The solid is the drawing envelope at FREE length, uncompressed; internal spring geometry, the retained plunger shoulder and the crimp are not drawn and not inferred. The catalog publishes nothing about the pad this pin mates against across a seam, so no mating-pad figure is recorded. Current at working stroke, resistance after cycling, fretting under vibration, and behaviour across a hand-assembled joint remain unvalidated.
