It is the male half of the crimp termination system — you crimp this pin onto a 20-24 AWG wire, then insert it into the appropriate HDP-20 pin housing. The stamped construction keeps per-contact cost down compared to the machined pins in the same series, while the gold flash plating on the brass base gives enough corrosion protection for typical equipment-room duty cycles.
Wire sizing and termination reality
The crimp barrel accepts 20-24 AWG stranded wire — that is the range the contact is designed to grip without cold flow or pull-out. Use the TE-certified crimp tool (typically a frame-and-die set from the PRO-CRIMPER III family) to get the correct crimp height for the wire gauge. A too-heavy crimp on 20 AWG or a loose crimp on 24 AWG both risk intermittent contact in the mated D-sub shell.
