Deutsch Autosport AS 55-Way Inline — Pin (Male) — Orange Key (C)

The Deutsch Autosport AS 55-Way Inline Pin (Male) Connector with Orange (C) Keying Insert — SKU: AS122-55PC is a professional MIL-spec-grade motorsport connector for high-density ECU main harness connectors, full PDM system separable joins, and complex race car loom interfaces 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 55 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 — 55-circuit Inline Connector

The Deutsch AS series is the standard Autosport circular connector format for professional motorsport — providing the 55-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. Delivers very high circuit density for ecu main harness interfaces and complete pdm wiring system separable joins — typically used where the entire ecu sensor loom and a significant portion of the pdm output wiring must cross a single separable join point. The 55-circuit AS inline is specified for main ECU harness interfaces and full PDM wiring system separation points where maximum circuit density in a single mid-size connector is required.

Orange Key (C) — The third keying position in the deutsch as system

As the third keying position in the Deutsch AS system, the Orange C key is the third unique key assignment in a multi-connector harness featuring three or more 55-way AS inline connectors at the same separation point. Orange C is the third key assignment — used on harnesses where three or more connectors of the same circuit count are needed. Common in complex ECU main looms, PDM harnesses, and full race car harness builds where multiple same-size AS inline joins are required between the engine bay and chassis. Three-key harness arrangements are typically found in the most complex full race car loom builds — where a single engine-to-chassis separation point must carry more circuits than two 55-way connectors alone can provide.

Contact Type — Pin (Male)

This listing is for the pin half of the 55-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.
