MS3476A20-39S is a MIL-DTL-26482 Series II Straight Plug (MS3476) on shell 20, arrangement 20-39, with 39 × #20 socket contacts. Series II is the crimp, rear-release removable-contact branch of MIL-DTL-26482 — it keeps the Series I bayonet (1/3-turn) coupling and insert arrangements but adds a rear-release contact system for higher-density production harnesses. Class A gives the black anodised finish for service from -55 °C to +125 °C. The MS part number is shared by every QPL source (Airoadcon, Amphenol, ITT Cannon, Souriau, Conesys / Aero-Electric).
