Deutsch Autosport ASU (Ultra-Miniature) Series — 5-Way Plug Pin (Male)
The Deutsch Autosport ASU 5-Way Plug Pin (Male) — Blue Key (B) — SKU: ASU603-05PB-HE is a genuine MIL-spec-grade cable-mounted plug connector for 5-circuit sensor cluster and actuator bundle separable joins in professional race cars, rally, hillclimb, and high-performance builds across Norway, Sweden, and Denmark. This is the pin half of the mated pair — Socket (Female) must be ordered separately to complete the join.
Shell and Circuit Count — ASU603, 5-Way
The ASU series is the smallest-format circular connector in the Deutsch Autosport family, designed for ultra-compact sensor sub-assemblies, low-channel signal interfaces, and weight-critical race car loom builds where the standard AS or ASX body is too large. The ASU603 is the ASU603 — ultra-miniature plug (free cable-mounted half) of the ASU connector pair. At 5 circuits, this connector is suited to 5-circuit sensor cluster and actuator bundle separable joins. Common applications include 5-wire sensor clusters, combined power/ground/signal interfaces, 5-channel switch pack sub-connectors, and mixed signal and power actuator bundles.
Blue Key (B) — Mis-Mate Protection
Blue B is the second key assignment, used when two parallel 5-circuit ASU plug bundles share the same separation point. Once Yellow A is allocated to the primary bundle, Blue B identifies the secondary — physically preventing cross-mating between the two pairs. Mis-mate protection is mechanical and holds regardless of time pressure or connector volume. Blue B and Yellow A are the standard two-key pairing used by harness builders across Norway, Sweden, and Denmark.
Plug Half — Free Cable-Mounted Connector
The plug is the removable, cable-mounted half of the connector pair — the half the technician handles and disconnects during harness separation. It mates with a fixed socket or flange-mount body to complete the separable interface. The push-pull locking collar engages with the fixed socket, creating a positive, vibration-resistant mated connection. Plug halves are supplied by Arctic Performance Parts to harness builders and race teams across Norway, Sweden, and Denmark.
