Housing First, Contacts Later — The 12-Way Mod IV Receptacle
It is a free-hanging (in-line) design, so there is no panel flange or PCB retention feature — the harness floats and relies on the mating header's board lock for strain relief.
What It Does Not Include — And Why That Matters
This housing ships empty.
Mating and Fit — Which Headers Work
That includes both shrouded and unshrouded headers from the same series — the receptacle housing has no keying or polarization feature beyond the standard Mod IV profile, so it accepts a straight or right-angle header as long as the pin count and pitch match. Because the housing is free-hanging, the mated pair relies on the header's board retention (solder tails or board locks) to keep the connection stable under cable strain.
