The MS3476L12-10S is a MIL-DTL-26482 Series II straight plug in shell size 12 with insert arrangement 12-10, carrying 10 × #20 crimp contacts. Series II is the rear-release crimp generation: contacts are inserted and extracted from the rear with standard M39029 tooling, which cuts harness assembly time versus Series I solder cups.
On Series II the letter following the MS347x style code is the finish code, not a service class. Class L here is electroless nickel (conductive, environmental). The insert arrangements themselves are the same MIL-C-26482 layouts as Series I — only contact retention and tooling differ.
Each #20 contact is rated 7.5 A at 20 °C; the assembly is rated 600 VAC (RMS) and operates from -55 °C to +125 °C with 5,000 MΩ minimum insulation resistance. Airoadcon supplies the same MIL part number, interchangeable with the original QPL manufacturers.
