The TE Connectivity 1-66504-0 is a stamped socket contact from the AMPLIMITE HDP-20 series, designed for crimp termination to 20-24 AWG wire. The gold flash finish on the phosphor bronze base provides corrosion resistance for moderate mating cycles in industrial or telecom equipment.
Wire Range and Termination Fit
Rated for 20-24 AWG stranded or solid wire, this contact accepts the typical signal and low-power conductor sizes used in D-sub backshells and panel-mount connectors. The crimp barrel is sized for the full strip length; a standard Mil-spec or commercial crimp tool with the correct die (e.g., for AMPLIMITE contacts) ensures consistent pull-off force. Gold flash on the mating surface keeps contact resistance low without the cost of thicker plating, suitable for connections that are mated and unmated a few dozen times over the equipment life.
