The profile of connectors above the PCB. Vertical connectors denote the stacking profile in parallel PCB applications, right angle connectors denotes height above the PCB.
Polarisation allows connectors to be plugged together in only the correct mating orientation. Achieved by a polarisation cutout or ‘key’ on PCB headers and raised polarisation bump on female connectors. Select both ‘key’ and ‘bump’ to view all polarised parts.
