Deutsch Autosport AS 55-Way Inline — Pin (Male) — Red Key (N)

The Deutsch Autosport AS 55-Way Inline Pin (Male) Connector with Red (N) Keying Insert — SKU: AS122-55PN 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.

Red Key (N) — The standard non-keyed (neutral) position in the deutsch as system

As the standard non-keyed (neutral) position in the Deutsch AS system, the Red N (neutral/non-keyed) option is the correct choice when only a single 55-way AS inline connector is used at this separation point on the harness — and no mis-mate risk exists between multiple same-size connectors. Red N is the neutral (non-keyed) option — an N-keyed connector will mate with any other N-keyed connector of the same circuit count regardless of which specific N-keyed half it is. Red N is the correct choice for single-connector applications where only one AS connector of this circuit count is used on the harness, or where a specific mis-mate prevention requirement does not exist. Red N-keyed 55-way inline connectors are widely used on race car harness builds where a single high-circuit-count connector handles the full harness separation at a given point, with no adjacent same-size connector that could be accidentally cross-mated.

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.
