Crimp termination, 22-26 AWG range
The 1-175161-1 is a tin-plated socket contact from TE's CT series, accepting 22-26 AWG wire with a crimp termination. The contact finish thickness is 10.0µin (0.25µm) — a standard tin layer for signal-level current in a dry environment.
Tin plating and wire fit
Tin-plated contacts mate well with tin-plated header pins in the same CT series; the 10.0µin (0.25µm) finish suits applications where the mating cycle count stays under 25. The 22-26 AWG range covers common signal and low-power wiring — the crimp barrel deforms around the conductor strands, so the strip length and tool die must match the wire gauge.
