Board-to-Board Receptacle with Outer Shroud Contacts
The Hirose FX2CA-20S-1.27DSA(71) is a 20-position board-to-board receptacle from the FX2 series, designed with outer shroud contacts that wrap around the mating interface. Through-hole termination locks the connector into the PCB for mechanical stability in the stack.
What Mates with This Receptacle?
This receptacle mates with the corresponding FX2 series header — look for the FX2BA or FX2CA header variant with the same 20-position, 1.27 mm pitch, dual-row layout. The outer shroud on the receptacle accepts the header's pin blade, providing alignment and a degree of EMI containment between the boards. Confirm the header's stacking height matches your board-to-board gap before specifying.
