Gold crimp socket for 26-30 AWG wire
The 170205-3 is a gold-plated socket contact in the TE EI series, designed for crimp termination onto 26-30 AWG wire.
Gold vs tin plating in the EI series
The 170205-3 carries gold contact finish for the 26-30 AWG range, while the 170205-1 and 170205-2 are tin-plated versions at the same wire gauge — gold suits higher mating-cycle or corrosive-environment duty. For heavier 20-26 AWG wire, the 170204-4 offers the same gold crimp socket in the EI series.
