It uses outer shroud contacts in a dual-row layout, mates with the matching FX2 series header, and includes an integrated strain relief for cable exit. The free-hanging (in-line) mount and IDC termination make it a straight fit for mass-terminated ribbon-cable harnesses in internal equipment wiring. The 40 positions at 1.27 mm pitch match standard ribbon cable — the IDC termination punches through the insulation in one press, no wire stripping. Gold flash on the contacts covers the mating surface; it's a light plating suited for low-cycle internal connections where corrosion resistance is secondary to cost. The outer shroud contacts mean the receptacle wraps around the header pins, giving some mechanical protection during mating. The built-in strain relief takes the tug off the IDC termination point. ## Where It Goes — Internal Ribbon-Cable Harnesses This is a board-to-board or board-to-peripheral interconnect inside an enclosure — think a disk-drive ribbon to a controller card, or a parallel data bus between PCBs in industrial gear. The free-hanging receptacle sits on the cable end, not soldered to a board. It's not sealed or rated for vibration-heavy environments; it's an internal, low-stress signal connection.","metaTitle":"Hirose FX2B-40SA-1.27R(02) 40-Position IDC Receptacle","metaDescription":"Hirose FX2 series 40-position IDC receptacle, 1.27 mm pitch, free-hanging, gold flash contacts.
