Stamped Socket for HDP-20 D-Sub Housings
It accepts 18-22 AWG wire and carries a 30.0µin (0.76µm) gold plating on the contact finish — that thickness is well into the field-service grade, good for repeated mating cycles in equipment that gets reconnected during maintenance. The phosphor bronze base material gives a spring temper that holds crimp force over the wire range without relaxing.
This socket uses a standard crimp termination — no solder, no insulation displacement. The 18-22 AWG range covers the most common signal and low-power wire sizes for D-sub pinouts in control cabinets and serial interfaces. The stamped construction keeps the contact cost lower than a machined version, which matters when you are populating a 25- or 37-position connector and the BOM quantity runs into the hundreds.
Plating Grade and Mating Duty
That thickness is standard for AMPLIMITE HDP-20 contacts that see field service — it resists corrosion in industrial cabinet environments and holds contact resistance stable through dozens of mate-unmate cycles. For a one-time permanent harness build, a lesser plating would work; for a connector that gets unplugged during panel rework, this is the right call.
