The 1-2842142-0: The gold flash provides corrosion resistance for occasional mating cycles — expect several hundred cycles before wear-through, suitable for field-service or rework scenarios.
Surface-mount termination with a pick-and-place feature — the flat top of the header allows vacuum nozzle pick-up during automated assembly. The insulation height is only 1.50 mm, keeping the z-height low in stacked board designs. Contact posts are tin-plated (2.00 µm) for reliable solder wetting; the mating contact length of 4.00 mm provides sufficient wipe for a stable connection.
RoHS3 compliant.
