Board-to-board receptacle, 40 positions, SMT
The 87024-620CTLF is the 40-position member of Amphenol ICC's Rib-Cage™ receptacle line, a board-to-board socket on 1.27 mm pitch in a dual-row layout. Mating contacts are gold or GXT™ plated, 30.0 µin (0.76 µm) thick, over beryllium copper — the beryllium copper spring beam holds contact force through repeated mating cycles without permanent set. The housing is rated UL94 V-0; the receptacle includes a board guide and a pick-and-place pad for automated assembly.
Contact material and plating
The beryllium copper contact material combined with 30.0 µin (0.76 µm) gold or GXT™ plating on the mating surface gives the 87024-620CTLF a high mating-cycle endurance — the contact beam resists relaxation and the thick gold layer resists fretting corrosion in industrial and telecom environments.
