What this header fits and why it holds
In a field-service setting where a conveyor or panel door cycles the connection, that ramp is what stops intermittent contact from a loosened pair.
Through-hole mounting with kinked pin solder termination. The kinked pins provide retention during wave soldering and resist pull-out from cable strain after assembly. Insulation height of 0.555" (14.10mm) gives clearance for the mating receptacle's latch. Mated stacking height is 19.4mm — confirm this fits your enclosure's z-height budget before committing the BOM line.
