Deutsch Autosport AS022 — 55-Way Flange Pin (Male) — Orange Key (C)
The Deutsch Autosport 55-Way Flange Pin (Male) Connector — Orange Key (C) — SKU: AS022-55PC is a genuine MIL-spec-grade Deutsch Autosport AS series panel-mounted connector built for 55-circuit primary vehicle loom separation points on full professional race car builds in professional race cars, hillclimb, rally, and high-performance builds across Norway, Sweden, and Denmark. Configured as a flange-mount (panel/bulkhead) separable join, this connector is fixed to a chassis panel, firewall, or bulkhead surface via its integral mounting flange — delivering a clean, reliable, mechanically keyed separable interface at the harness separation point.
AS022 Shell — Series Architecture and Circuit Density
The AS022 is a very large circular flange-mount shell offering circuit counts from 21 to 100 ways — delivering the highest circuit consolidation per flange-mount connector pair across the full AS series. The AS022 is used for absolute maximum circuit density at a single bulkhead separation point, combining MIL-spec aluminium alloy construction, gold-plated contacts, and positive push-pull locking in a large circular panel-mount body. The 55-circuit configuration in the AS022 shell is suited to 55-circuit primary vehicle loom separation points on full professional race car builds. Typical applications at this circuit count include full vehicle primary loom engine-to-chassis separation joins, consolidated ECU and PDM main harness combined splits, high-density vehicle-wide circuit consolidation at a single bulkhead separation point. The 55-way flange is a very high circuit count available in both the AS016 and AS022 shells, approaching maximum circuit consolidation achievable in these shell sizes.
Pin (Male) — 55-Circuit Contact Array
This listing supplies the pin half of the 55-way AS flange connector pair — gold-plated pin contacts 55 in total — carrying each circuit across the flange-mount (panel/bulkhead) separation point. To form a complete functional connector pair, the matching Socket (Female) half of the same circuit count, shell size, and key colour must be ordered separately; both halves are required to create a mated, functional separable join. AS series contacts are ordered independently of the connector shells — select the correct contact part number for your wire gauge, current rating, and preferred termination method.
Orange Key (C) — Keying Position and Mis-Mate Protection
Orange C is the third key position, assigned to the third 55-circuit AS flange bundle at a separation point where three parallel connector pairs are required. With Yellow A on the first bundle and Blue B on the second, Orange C completes the three-connector mis-mate protection scheme — preventing any of the three 55-circuit pairs from being accidentally cross-mated during reconnection. Three-connector keying arrangements appear in complex loom builds where the combined circuit count at a single split demands three independent 55-circuit groups running in parallel. Professional harness builders working on high-complexity race car looms in Norway, Sweden, and Denmark reach for Orange C when a third 55-circuit AS flange pair is required at the same separation point alongside Yellow A and Blue B.
Flange Configuration — Panel and Bulkhead Mounting
The AS flange connector mounts through a panel cutout using its integral aluminium mounting flange — fixing one half of the connector pair permanently to the chassis, firewall, or bulkhead surface. The mating free half (the cable-mounted opposite half) plugs directly into the panel-mounted half, creating a secure separable interface at the bulkhead itself. This configuration is used wherever the harness must separate cleanly at a fixed chassis point — engine bay to cabin firewall, removable subframe to chassis, fuel cell bay to main loom, or any other fixed panel location where one side of the harness needs a permanent, precision-located connection point. Flange connectors are the professional standard for primary chassis separation points in full race car loom builds. Flange-mount AS connectors are the standard choice for primary chassis and bulkhead separation points on race cars and high-performance vehicles built and maintained by loom specialists and motorsport workshops across Norway, Sweden, and Denmark.
