It should also be noted (I did not realize when buying and testing) that this is a pure 1: 1 pin header, that is, each pin goes right through the bar through it.
This component is not suitable for eg connecting a DOM (Disk-On-Module) to an IDE Drive Link, because a specialist Coded adapter is required.
With an adapter in this case, the pins are cross-connected, coded means, 1 pin is lacking, so DOM and IDE Drive link can not be connected incorrectly.
