Board-to-Board Receptacle for Mezzanine Stacks
The 55510-112TR: The 2.00mm pitch and 0.177" (4.50mm) insulation height set the mated stack height and board spacing — typical for signal-level interconnects in industrial control, medical equipment, and general-purpose electronics. The 2A per-contact rating at 200V covers low-power signal and sensor circuits.
