Deutsch Autosport AS 22-Way Flange — Socket (Female) — Green Key (D)
The Deutsch Autosport AS 22-Way Flange Socket (Female) Connector with Green (D) Keying Insert — SKU: AS012-35SD is a professional MIL-spec-grade Deutsch Autosport AS series connector for medium-high-density ECU sub-harness connectors, PDM wiring interfaces, and complex multi-circuit motorsport loom separable joins in race cars and high-performance vehicles across Norway, Sweden, and Denmark. As a flange connector, the 22-way AS provides a fixed medium-high-density panel interface for ECU sub-loom and PDM harness bulkhead separation points.
Deutsch Autosport AS 22-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 22-way AS is a well-established circuit count in professional motorsport harness builds — providing high circuit density in a mid-size shell used for ECU sub-loom joins, PDM input/output harness interfaces, and complex multi-circuit race car loom separation points.
Socket (Female) — 22-Circuit Contact Array
This listing is the socket half of the 22-way AS flange pair. Twenty-two socket contacts receive twenty-two individual pin contacts — the receptacle half completing the full medium-high-density circuit complement across this motorsport harness separable join. The corresponding pin 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 flange separation point carrying four parallel 22-circuit bundles. When a panel carries multiple 22-circuit AS flange connectors — for example, a bulkhead with two parallel 22-circuit flange mounts for separate cable bundles — keying ensures each harness plug half can only mate with its own correct flange counterpart, preventing cross-mating errors during harness assembly and servicing. With all four keys assigned (Yellow A, Blue B, Orange C, Green D), four physically identical 22-circuit AS flange 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.
Flange Configuration — Panel-Mounted Fixed Connector Point
The AS flange configuration mounts permanently to a chassis panel, bulkhead, or firewall using the integrated flange holes — creating a fixed, chassis-anchored 22-circuit connector point that the harness cable-side plug half mates into from the wiring loom side. Flange connectors are specified at all harness separation points that align with a structural chassis surface — engine bay-to-chassis bulkheads, firewall primary harness separation points, and chassis rail panel interfaces.
Once bolted to the mounting surface, the AS flange connector remains in position throughout the vehicle’s race service life — the harness plug is mated and unmated repeatedly for component installation, removal, and servicing without disturbing the chassis-side flange. The 22-circuit AS flange provides the fixed connection point that makes systematic, repeatable harness separation possible at this chassis location on race cars and performance vehicles throughout Norway, Sweden, and Denmark.
