The MS3108A20-15S is a MIL-DTL-5015 90° angle plug in shell size 20 with insert arrangement 20-15, carrying 7 × #12 socket solder contacts. MIL-DTL-5015 is the original Army-Navy circular standard - the 5015 shell sizes and insert arrangements are the reference that the 26482, 38999 and VG95234 families each re-use in some form.
Class A is the solid shell, general purpose. The coupling thread for this shell is 1-7/16-18 UNEF, and the class-DJ, E, F and R variants add grommets, cable clamps or fluid resistance on the same shell. Note that two connectors can share a shell size and still be completely different inside: a shell-18 18-1 (10 × #16) and a shell-18 18-11 (5 × #12) look related on paper and are not interchangeable in practice.
Each #12 contact carries 23 A; the wider MIL-DTL-5015 range covers #16 at 13 A through #4 at 80 A. Solder versions use silver-plated contacts and olive drab cadmium shells as standard. Airoadcon supplies the same MIL part number, interchangeable with Amphenol 97-series and ITT Cannon CA-series equivalents.
