The TE Connectivity AMP-Latch 1-1658526-5 is a 26-position female socket receptacle designed for mass-termination to 28-30 AWG ribbon cable via IDC (Insulation Displacement Contact). The blue polarizing key prevents incorrect orientation during mating — a practical safeguard in multi-connector harnesses where several AMP-Latch receptacles sit side-by-side on the same cable.
The specified 28-30 AWG range covers the standard ribbon cable gauges used in internal data and signal harnesses.
Tin plating would suffice for a one-time install, but the gold here supports a higher reconnect duty without fretting corrosion at the interface.
