About this model
These tiny items fit into Dupont(R)-style pin header housings to prevent plugging it in unless a pin has been omitted in that location. This allows reasonable polarization protection while using common 0.1" (2.54mm) pin headers that normally could be plugged in backwards. This worked great for a 3-conductor cable; I just used a four-position housing and plugged up one of the interior holes. The first picture shows that preventing backwards connection. For a 6-pin cable, I didn't want to add just one position because 7-position housings are uncommon. So I added 2 positions and made a double plug for convenience. This is shown in the second picture. I had been using JST's MHT connectors on the board because they are polarized. But scaling this up proved a problem because the US$40 crimping p…
