Contact Metallurgy and Mating Cycle Life
The 87471-650LF: Beryllium copper is specified for the female socket contacts — a material choice that maintains elastic recovery over hundreds of mating cycles, resisting permanent set in the contact beam.
Mating Half and Build-to-Print Fit
This receptacle mates with a 100-position, 1.27 mm pitch board-to-board pin header from the same Rib-Cage™ series. The push-pull fastening and board guide on the receptacle align with the header's guide posts — build-to-print needs both halves specified on the BOM. Confirm the header's mating post height to meet the board-to-board spacing budget.
