It is the male terminal half that goes into a standard D-sub connector housing — you crimp it onto the wire, then insert it into the appropriate HDP-20 cavity.
Wire Gauge Range and Crimp Fit
This contact accepts 18-22 AWG stranded wire — the range covers the most common signal and low-power wire sizes in D-sub applications. The stamped construction keeps the contact consistent across high-volume crimp tooling; the brass body takes the crimp force without cracking the plating. For a harness builder, the 18 AWG end of the range gives the best pull-out retention; 22 AWG is fine for signal lines where flexibility matters more than tensile strength.
Plating Depth and Mating Cycle Reality
In a D-sub that sees quarterly reconnects over a decade, this plating grade keeps contact resistance stable. The tin-plated or thinner-gold variants in the same series trade cycle life for cost; the 745229-2 sits on the high-cycle side of that trade.
