Deutsch Autosport AS 3-Way Plug — Pin (Male) — Blue Key (B)
The Deutsch Autosport AS 3-Way Plug Pin (Male) Connector with Blue (B) Keying Insert — SKU: AS610-03SB 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 plug half that mates with a fixed flange or inline receptacle — the movable, harness-side component that disconnects for component removal, harness separation, and servicing.
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.
Pin (Male) — 3-Circuit Contact Array
This is the pin half of the 3-way AS plug pair. Three pin contacts transfer three individual circuits — each gold-plated contact making precision engagement with its socket counterpart when mated and locked. The corresponding socket 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 plug 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.
Plug Configuration — The Movable Cable-Mounted Connector Half
The AS plug is the free, cable-mounted half of the connector pair — it does not mount to a panel or chassis surface. The plug travels with the removable component or sub-harness and mates into a fixed receptacle (flange-mounted or inline) to complete the electrical circuit when the assembly is connected. This makes the plug the correct specification for engine-side harness connectors that must be disconnected for engine removal, dashboard harness sub-connectors that follow a removable dashboard assembly, removable subframe harness joins, and any other separable point where one connector half must be freely movable with a removable vehicle component.
The 3-circuit AS plug is used for 3-circuit sensor, solenoid, and small actuator separable joins across race cars and performance vehicles in Norway, Sweden, and Denmark. The plug’s free, unmounted format allows the harness builder to route the cable bundle freely from the removable component to the mating point without any chassis mounting constraint — then mate the plug directly into the fixed receptacle when the component is installed. The push-pull positive locking mechanism provides secure, vibration-resistant engagement that holds through race conditions while allowing intentional disconnection at every service interval.
