It is a female SMT connector designed for board-to-board stacking applications where signal density and a low profile matter. Typical use is in mezzanine or parallel-board interconnects inside telecom, server, or industrial control equipment. ## Stacking Height Flexibility This connector supports seven mated stacking heights: 10mm, 10.5mm, 11mm, 11.5mm, 12.5mm, 13mm, and 15mm. That range lets the designer choose the board-to-board spacing after the footprint is fixed — the same receptacle works across multiple enclosure z-height budgets. The 0.317\" (8.05mm) height above board is the receptacle's own body height; the total stack depends on the mating male header height. ## Assembly and Placement The connector includes a board guide and pick-and-place features, which simplify automated SMT assembly. The board guide aligns the part during placement, and the pick-and-place surface lets the nozzle handle it without disturbing the contacts. Tape & Reel packaging feeds directly into a pick-and-place machine.","metaTitle":"Molex SEARAY 465571545, 40-Position Female Array","metaDescription":"Molex 465571545 SEARAY high-density array, 40 positions, 4 rows, 0.050\" (1.27mm) pitch, gold 30.0µin plating, SMT, active production.
