Deutsch Autosport AS 4-Way Flange — Pin (Male) — Orange Key (C)
The Deutsch Autosport AS 4-Way Flange Pin (Male) Connector with Orange (C) Keying Insert — SKU: AS012-04PC is a professional MIL-spec-grade Deutsch Autosport AS series connector for compact 4-wire sensor, switch, and actuator harness separable joins in race cars and high-performance vehicles across Norway, Sweden, and Denmark. As a flange connector, the 4-way AS is panel-mounted to a chassis surface or bulkhead — providing a fixed 4-circuit connector point.
Deutsch Autosport AS 4-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 4-way AS is one of the most compact circuit counts in the AS series — used for simple 4-wire sensor assemblies, individual actuator connectors, and compact auxiliary circuit separable points where minimal size and weight are priorities.
Pin (Male) — 4-Circuit Contact Array
This listing is the pin half of the 4-way AS flange pair. Four gold-plated pin contacts carry each of the four individual circuits across this separable join — transferring signals and power from the harness-side loom to the corresponding socket half. 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.
Orange Key (C) — Keying Position and Mis-Mate Prevention
Orange C is the third key assignment for a flange separation point carrying three parallel 4-circuit bundles. When a panel carries multiple 4-circuit AS flange connectors — for example, a bulkhead with two parallel 4-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 Yellow A, Blue B, and Orange C assigned across three pairs, complete mis-mate protection is provided for all three 4-circuit AS flange pairs at this separation point — essential for the most complex full race car loom builds in Scandinavia.
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 4-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 4-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.
