MS3456KS20-29SY is a MIL-DTL-5015 Series III straight plug built with rear-release crimp contacts — the modern 'Series III' branch of the classic MS310x 5015 family. The part number decodes as shell style MS3456 (Straight Plug), service class KS, shell size 20 and insert arrangement 20-29, which carries 17 × #16. Contacts are terminated with standard M39029 crimp contacts rather than solder cups, and the coupling is the family's 3/4-turn threaded ring. Alternate insert position Y prevents cross-mating of adjacent connectors carrying different voltages or signals.
