The 1718560007: This 7-position header uses the classic 0.100" (2.54mm) pitch, which sets the board footprint and determines which receptacle it mates with. The friction lock is the key retention feature — it prevents the header from backing out of the mating receptacle under cable strain or vibration. No secondary latch needed.
The 1-wall shrouding guides the mating half and protects the pins during handling.
ROHS3 compliant. Bulk packaging.
