Deutsch Autosport AS 39-Way Inline — Pin (Male) — Green Key (D)
The Deutsch Autosport AS 39-Way Inline Pin (Male) Connector with Green (D) Keying Insert — SKU: AS120-39PD is a professional MIL-spec-grade motorsport connector for high-density ECU main harness sub-connectors, primary PDM wiring interfaces, and complex race car loom separable joins in race cars and performance vehicles across Norway, Sweden, and Denmark. This pin half is the active contact side — the gold-plated pin terminals mate with the corresponding socket (socket) half, transferring all 39 circuits across the inline separable join when the connector is locked. Configured as an inline connector — in-line harness separable join — both halves are free, cable-mounted connectors within the wire run.
Deutsch Autosport AS — 39-circuit Inline Connector
The Deutsch AS series is the standard Autosport circular connector format for professional motorsport — providing the 39-circuit capacity required for this application in a robust aluminium alloy shell with push-pull positive locking, gold-plated contacts, and full MIL-spec environmental sealing for race-condition reliability. Sits between the 37-way and 41-way configurations, providing high circuit density for primary ecu harness and pdm separable joins in professional motorsport builds. The 39-circuit inline is used for high-density ECU harness interfaces and primary PDM wiring separable joins where the 37-way circuit count is marginally insufficient and the 41-way is the next available option.
Green Key (D) — The fourth keying position in the deutsch as system
As the fourth keying position in the Deutsch AS system, the Green D key completes the four-position keying system — used when four 39-way AS inline connectors are required at the same separation point on a complex race car harness. Green D is the fourth key assignment in a multi-connector harness. The availability of four colour-coded keying positions (Yellow A through Green D) means that up to four identical-size AS connectors can be used on the same harness without any risk of mis-mating — covering virtually all professional motorsport harness separation point requirements. With all four key colours assigned (Yellow A, Blue B, Orange C, Green D), up to four physically identical 39-way AS inline connectors can be used at the same harness split without any possibility of cross-mating during assembly, servicing, or post-event connector repair.
Contact Type — Pin (Male)
This listing is for the pin half of the 39-way AS inline pair — the active contact half — the pin terminals make physical contact with the socket terminals when mated, transferring electrical signals and power across the separable join. The corresponding socket half of the same circuit count and key colour is required to complete the mated connector pair. AS contacts are ordered separately — select the correct contact part number for your wire gauge and current requirements.
