Deutsch Autosport AS 39-Way Plug — Pin (Male) — Yellow Key (A)

The Deutsch Autosport AS 39-Way Plug Pin (Male) Connector with Yellow (A) Keying Insert — SKU: AS620-39SA is a professional MIL-spec-grade Deutsch Autosport AS series connector for high-density ECU harness sub-connectors, primary PDM circuit interfaces, and complex race car loom separable joins in race cars and high-performance vehicles across Norway, Sweden, and Denmark. As a plug connector, the 39-way AS provides a high-density free plug half for ECU harness and PDM separable joins requiring exactly 39 circuits — bridging the 37 and 41-way range.

Deutsch Autosport AS 39-Way — Series Design and Circuit Application

The Deutsch Autosport AS series is the professional standard circular connector format for motorsport wiring — featuring an aluminium alloy shell machined to MIL-spec tolerances, gold-plated contact interfaces for consistent low-resistance electrical performance across the connector’s service life, and a positive push-pull locking mechanism that holds secure under sustained race vibration and rapid connector cycling at service intervals. The 39-way AS sits between the 37 and 41-way — used for high-density ECU main harness interfaces and primary PDM separable joins where the 37-circuit count is marginally insufficient.

Pin (Male) — 39-Circuit Contact Array

This listing is the pin half of the 39-way AS plug pair. Thirty-nine pin contacts carry thirty-nine individual circuits — the active contact array bridging the 37 and 41-way range in the Deutsch Autosport AS series. The corresponding socket half of the same circuit count and key colour is required to complete the mated connector pair — both halves must be ordered to form a functional separable join. AS contacts are ordered separately; select the correct contact part number for your wire gauge and current requirements.

Yellow Key (A) — Keying Position and Mis-Mate Prevention

Yellow A is the first key assigned in any AS plug harness keying plan. When a harness includes multiple 39-circuit AS plug connectors at the same separation point — for example, where two parallel 39-circuit cable bundles each have their own plug connector mating into a fixed receptacle panel — keying ensures each plug can only connect to its own correct receptacle, preventing cross-connection during harness assembly and race event connector operations. The Yellow A key tab on this plug half ensures it accepts only a matching Yellow A-keyed mating half — making it the primary connector in any multi-pair 39-circuit AS plug arrangement. Professional harness builders across Norway, Sweden, and Denmark standardise on Yellow A as the primary key for consistency across multiple builds.

Plug Configuration — The Movable, Cable-Mounted Connector Half

The AS plug configuration is a free, cable-mounted connector half — it does not mount to a panel or chassis surface. Instead, the plug is the movable, harness-side half that disconnects from a fixed receptacle (either a flange-mounted panel connector or a corresponding inline half) to allow component removal, harness separation, and servicing. The plug carries the cable bundle from the removable component or sub-harness and mates into the fixed chassis-side or loom-side receptacle when the system is assembled.

The 39-way AS plug is used for high-density ECU and PDM primary interface removable joins in race cars and performance vehicles across Norway, Sweden, and Denmark. The plug format is specified wherever one connector half must be freely movable — for example, at engine removal points where the engine-side harness plug disconnects from the chassis-side flange, at removable dashboard assemblies where the instrument harness plug mates into a fixed bulkhead connector, and at any harness separation point where the plug side follows a removable component when it is extracted from the vehicle.

Unlike flange or inline connectors that create a two-sided free connection, the AS plug is always the movable half in a plug-to-receptacle pair — providing the connector architecture needed for clean, repeatable component removal and installation across the race service life of the vehicle.
