The 5-103948-3: The closed-end feature prevents the cable from pushing through the housing during termination, which keeps the wire alignment consistent across the row.
No stripping, no crimping, no soldering. The 26-30 AWG range covers common 0.025"-pitch ribbon cable; a 28 AWG cable falls right in the middle of that range and is fully compatible. The single-row, 4-position layout is common for low-count signal buses or sensor interfaces where space on the PCB edge is tight.
