Deutsch Autosport AS 37-Way Inline — Socket (Female) — Red Key (N)

The Deutsch Autosport AS 37-Way Inline Socket (Female) Connector with Red (N) Keying Insert — SKU: AS114-35SN is a professional MIL-spec-grade Deutsch Autosport AS series connector for high-density ECU main harness sub-connectors, full PDM wiring system interfaces, and primary race car loom separable joins in race cars and high-performance vehicles across Norway, Sweden, and Denmark. Configured as a free, cable-mounted inline connector — both halves are cable-mounted within the wire run, creating a separable interface at any intermediate harness point without requiring a panel or chassis mounting location.

Deutsch Autosport AS 37-Way — 37-circuit Circuit Configuration

The Deutsch Autosport AS series is the professional standard circular connector format for motorsport wiring — aluminium alloy shell, gold-plated contacts, positive push-pull locking, and full MIL-spec environmental sealing for race-condition reliability. The 37-circuit configuration is used for ECU main harness sub-joins and PDM wiring system separable interfaces — one of the most widely-specified circuit counts in professional Scandinavian motorsport in professional motorsport builds throughout Scandinavia. Primary 37-circuit high-density shell — one of the most widely-specified as configurations in professional motorsport harness design.

Socket (Female) — 37-Circuit Contact Array

This is the socket half of the 37-way AS inline pair. Thirty-seven socket contacts receive thirty-seven pin contacts — the receptacle half completing the full 37-circuit complement at this primary motorsport connector. The corresponding pin half of the same circuit count and key colour completes the mated pair — both halves are required. AS contacts are ordered separately; select the correct contact part number for your wire gauge and current requirements.

Red Key (N) — Keying Position and Mis-Mate Prevention

Red N is the neutral (non-keyed) specification — the correct choice when only a single 37-circuit AS inline is used at this separation point and no adjacent same-size connector creates a mis-mate risk. An N-keyed half mates with any other N-keyed half of the same circuit count, keeping the connector specification simple and straightforward for single-pair 37-circuit AS applications. Red N is also commonly used on initial harness prototype builds before the final keying strategy is confirmed, on harnesses where each AS connector is a unique circuit count (eliminating any possibility of mis-mating by design), and on any motorsport harness build in Norway, Sweden, or Denmark where keyed mis-mate prevention between same-circuit-count connectors is not required at this particular separation point.

Inline Configuration — Harness Separation Without a Fixed Mount

The AS inline configuration places the separable join entirely within the harness run — neither connector half mounts to a panel or chassis surface. Both the pin half and the socket half are free, cable-mounted connectors that can be separated at any point along the wire run, providing complete flexibility in separation point placement without needing a suitable mounting surface.

The 37-circuit AS inline is used for high-density ECU main harness sub-connectors, full PDM wiring system interfaces, and primary race car loom separable joins across race cars and performance vehicles in Norway, Sweden, and Denmark. The inline format is specified for engine-to-chassis harness separation points where no chassis panel is available for a flange mount, for removable subframe and component harness joins within the wire loom, and for any separable interface within the harness where both halves must remain free. The inline pair routes cleanly through the same harness trunk or loom sleeve, with both halves mated and the connector pair tucked into the harness bundle when assembled.
