Deutsch Autosport AS 3-Way Inline — Socket (Female) — Blue Key (B)
The Deutsch Autosport AS 3-Way Inline Socket (Female) Connector with Blue (B) Keying Insert — SKU: AS107-98SB is a professional MIL-spec-grade Deutsch Autosport AS series connector for 3-circuit sensor, solenoid, and small actuator separable joins in race cars and high-performance vehicles across Norway, Sweden, and Denmark. Configured as a free, cable-mounted inline connector — both halves are cable-mounted within the wire run, creating a separable interface at any intermediate harness point without requiring a panel or chassis mounting location.
Deutsch Autosport AS 3-Way — 3-circuit Circuit Configuration
The Deutsch Autosport AS series is the professional standard circular connector format for motorsport wiring — aluminium alloy shell, gold-plated contacts, positive push-pull locking, and full MIL-spec environmental sealing for race-condition reliability. The 3-circuit configuration is used for compact 3-wire sensor assemblies, individual solenoid connectors, and simple auxiliary harness joins in professional motorsport builds throughout Scandinavia. Compact 3-circuit shell — suited for sensor sub-harness removable joins and individual actuator connections.
Socket (Female) — 3-Circuit Contact Array
This is the socket half of the 3-way AS inline pair. Three socket contacts receive three incoming pin contacts — each completing one of the three circuits when the push-pull lock is engaged. The corresponding pin half of the same circuit count and key colour completes the mated pair — both halves are required. AS contacts are ordered separately; select the correct contact part number for your wire gauge and current requirements.
Blue Key (B) — Keying Position and Mis-Mate Prevention
Blue B is the second key assignment in a Deutsch AS multi-connector harness plan — allocated to the second 3-circuit AS inline connector pair once Yellow A has been assigned to the first. The Blue B physical key tab prevents this half from mating with a Yellow A, Orange C, Green D, or Red N keyed counterpart — ensuring the second 3-circuit bundle can only be reconnected to its own correct mating half, even when multiple identical-size connectors are physically close together in the same harness routing area. The Yellow A / Blue B two-key arrangement is the most common keying strategy used across professional motorsport harness builds in Norway, Sweden, and Denmark when two 3-circuit AS connectors appear at the same separation point — providing full mis-mate protection with minimal keying complexity.
Inline Configuration — Harness Separation Without a Fixed Mount
The AS inline configuration places the separable join entirely within the harness run — neither connector half mounts to a panel or chassis surface. Both the pin half and the socket half are free, cable-mounted connectors that can be separated at any point along the wire run, providing complete flexibility in separation point placement without needing a suitable mounting surface.
The 3-circuit AS inline is used for 3-circuit sensor, solenoid, and small actuator separable joins across race cars and performance vehicles in Norway, Sweden, and Denmark. The inline format is specified for engine-to-chassis harness separation points where no chassis panel is available for a flange mount, for removable subframe and component harness joins within the wire loom, and for any separable interface within the harness where both halves must remain free. The inline pair routes cleanly through the same harness trunk or loom sleeve, with both halves mated and the connector pair tucked into the harness bundle when assembled.
