I have found them to be not nearly as weather-tight as Deutsch and other newer technologies. I finally found these as Packard Electric Systems connectors and they are now part of Delphi Electronics as are many of the others you’ll see out there. Here’s a link to Mousers site that lists all the Delphi connectors at Mouser.
There are almost 6,000 items and you can browse the page and click on the connector that looks like the one you want then find additional information from there.
There are two different versions of these Weather-Pack connectors. The difference is the locking mechanism that holds the two mating connectors together. I’ve seen both on the same piece of equipment. Fig. 1 gives you some detail.
The sexing terminology used is “Tower” for the female and “Shroud” for the male. Parts include the tower or shroud, pins or sockets and the insulator, which is available in lots of sizes. The connectors are used by some component manufacturers.
Position sensors used by Case IH, John Deere, Trimble, Ag Leader and others are “reverse polarity.” These have the female connection in the shroud, in this case you need to build the connector backwards. You’ll find the pins and sockets don’t want to align properly but it works. A position sensor is shown in Fig. 2.
In my next installment, I’ll be taking a look at the Metri-Pack Series of connectors, which we tend to see more commonly used in the automotive industry.
