SEAMI-40-11.0-S-10-2-A-K-TR

Back-to-board connectors like this 1.27mm pitch header enable compact interconnection between stacked PCBs in high-density applications such as mobile computing devices, data center blade servers, and industrial control modules where space constraints are critical. The 85-ohm impedance and SMT mounting support signal integrity in multi-row applications requiring reliable mating across dozens of signal lines.
