What the 6.50mm pitch and right-angle orientation buy you
The 2035551216: This is a 6-position, 2-row header from the CP-6.5 203555 series, rated for general-purpose and industrial use. The shrouded 4-wall design protects the rectangular tab contacts from being bent during handling or blind mating.
Latch holder and board guide keep the pair mated
The latch holder (fastening type) locks the mating receptacle in place — critical in equipment that sees vibration from fans, motors, or transport. The current rating varies by wire gauge, so the limiting factor is the wire and terminal, not the header itself.
