Power socket contact for 12 AWG crimp termination
The 1648384-1 is a power socket contact from TE's ELCON series, accepting 12 AWG wire and terminating by crimp.
What the 35 A rating and gold plating mean for the fit
The 35 A per-contact rating and gold plating suit repeated mating cycles in power-distribution applications where the contact sees infrequent but reliable engagement. Crimp termination for 12 AWG means the wire barrel matches a standard ELCON applicator — retooling the press for a different terminal size is not needed.
