24 Circuits at 0.100" Pitch — Board Fit and Current Ceiling
The 68021-124HLF: Each contact is rated 3 A, and with all 24 positions loaded, the total current budget across the connector is 72 A, though in practice the temperature rise at the centre pins will limit the per-contact derating above 25°C ambient. The 0.230" (5.84 mm) mating contact length gives enough wipe for a reliable interface with standard female sockets.
Gold Plating and Mating-Cycle Life
The mating surface carries 30.0 µinch (0.76 µm) of gold over nickel — this is a mid-grade plating that supports several hundred mating cycles in a clean environment.
The 68021 family shares the same 0.100" pitch, dual-row layout, right-angle orientation, gold plating, and 3 A rating.
