Board density and footprint fit
The 6-104069-2: The 0.050" (1.27 mm) pitch on this 24-position, dual-row header sets the PCB footprint density. That saves z-height in enclosures where a vertical header would hit the lid.
Mating interface and cycle life
Through-hole termination and board anchoring
The through-hole pins take the mechanical strain from cable pull, unlike an SMT connector that relies on pad adhesion.
UL94 V-0 housing — the thermoplastic won't sustain a flame inside equipment that requires a flammability rating. RoHS3 compliant per current directive.
