6-position, 2.54 mm pitch, right-angle header with friction lock
The 1718571006: It is part of the KK254 series and carries a shrouded 1-wall design with a friction lock for secure mating in vibration-prone environments. The insulation is black polyamide rated UL94 V-2.
This header mates with KK254 series crimp receptacle housings (e.g., 50-57-9406 or similar 6-position single-row housings) using the matching crimp terminals (e.g., 08-50-0114 or 08-50-0106). Build-to-print needs both halves and the contacts — the header alone is one side of the assembly.
