It is a shrouded 4-wall header with a latch holder fastening system, meaning the mating receptacle locks positively against cable pull – a real advantage in equipment that sees vibration or frequent handling.
Tin-to-tin contacts are cost-effective for moderate mating cycles.
Board guide and polarizing key – assembly error protection
The header includes a board guide and a polarizing key. The polarizing key ensures the mating receptacle can only be inserted one way, preventing reverse-polarity connections. The insulation height is 0.465" (11.80 mm), and the mating pin length is 0.240" (6.10 mm) – enough to engage the receptacle contact fully before the latch clicks.
