I ordered a Newark Electronics catalog about two weeks ago and it finally came in on Monday. It turns out that the technical name for the plugs is "Mod IV Nonpolarized Wire-Applied Housings" and the crimpable pins that go inside are called "Snap-in Mod IV Pin and Receptacle Contacts". Newark sells the housings in single or double row with 2 to 7 pins per row. Note that these housings are rectangular and not keyed, just like the ones our team has been using thus far.
