Panel mounting from the rear of a bulkhead, with the jam nut locking the shell onto the panel.
MS3474W22-55P is the jam nut receptacle of MIL-DTL-26482 Series II. Series II keeps the Series I bayonet interface and MIL-STD-1669 inserts but replaces solder cups with rear-release crimp contacts held by a beryllium-copper clip. Shell 22 with insert 22-55 carries 55 × #20. A Series I plug of the same shell size, insert and polarization will still mate; the contacts, tools and backshells do not interchange.
