| Pole notation | Most drawings show 2×XXP for per-row count; the KNRHM ordering diagram shows XXP. Specify both row count and total contacts when ordering. |
| Colour field Y | 1 grey; 2 blue; 3 black; 4 green; 5 orange; 6 red; 7 transparent; 8 yellow; 9 white |
| Customer suffix | 000A after colour in the model drawings |
| General screw-head field | 0 slot; 1 cross |
| General screw-clamping field | 0 screw down; 1 screw up |
| General standard-product field | 0A |
The general legend covers the wider terminal range. Its 02–99 pole field does not extend this range, and its screw fields do not define wire clamps on these PCB headers. The legend does not establish every colour and screw-option combination for every model.
N is the number of contacts in one row, from 2 to 24; total contacts equal 2N. All formulas give millimetres.
