Deutsch Autosport AS 41-Way Plug — Pin (Male) — Green Key (D)

The Deutsch Autosport AS 41-Way Plug Pin (Male) Connector with Green (D) Keying Insert — SKU: AS620-41SD is a professional MIL-spec-grade Deutsch Autosport AS series connector for primary ECU harness separable joins, main PDM wiring interfaces, and high-density motorsport loom separation points in race cars and high-performance vehicles across Norway, Sweden, and Denmark. As a plug connector, the 41-way AS is one of the most widely-used AS plug configurations in professional motorsport — the primary high-density cable-mounted plug half for ECU main harness joins and PDM wiring system separable interfaces in race cars across Norway, Sweden, and Denmark.

Deutsch Autosport AS 41-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 41-way AS is one of the most widely specified circuit counts in professional motorsport harness design — used across circuit racing, rally, and endurance motorsport throughout Scandinavia for primary ECU main harness and PDM wiring system separable interfaces.

Pin (Male) — 41-Circuit Contact Array

This listing is the pin half of the 41-way AS plug pair. Forty-one gold-plated pin contacts transfer forty-one individual circuits simultaneously — the active array of the most widely-specified high-circuit-count configuration in professional motorsport AS harness design. 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.

Green Key (D) — Keying Position and Mis-Mate Prevention

Green D completes the four-key set at a plug separation point carrying four parallel 41-circuit bundles. When a harness includes multiple 41-circuit AS plug connectors at the same separation point — for example, where two parallel 41-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. With all four keys assigned (Yellow A, Blue B, Orange C, Green D), four physically identical 41-circuit AS plug connectors can operate at the same separation point with complete mis-mate prevention under all conditions — the maximum keying complexity available in the Deutsch AS system.

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 41-way AS plug is used for primary ECU main harness and PDM system removable separable joins across professional Scandinavian motorsport 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.
