The 40-position variant is the mid-density option — it matches a 40-signal bus without wasting board space on unused contacts, while the 20-position is for narrower data paths and the 52-position for wider parallel interfaces. All three carry the same 7.87 µin gold plating and board lock feature, so the choice is purely a circuit-count decision against the BOM.","metaTitle":"Hirose FX2B-40PA-1.27DSL(71) 40-Pos 1.27mm Board-to-Board","metaDescription":"Hirose FX2B-40PA-1.27DSL(71) board-to-board plug, 40 positions, 1.27 mm pitch, right-angle through-hole, gold contacts, board lock.
