8STA6-20-35SN — 79-Way Souriau 8STA Inline Plug Motorsport Connector (Socket (Female), N keyway (neutral / no polarisation key))
The 8STA6-20-35SN is a 79-way Souriau 8STA series cable-to-cable or cable-to-panel inline plug with socket (female) contacts and N keyway (neutral / no polarisation key). The 8STA series is the professional motorsport circular connector standard used by factory racing teams and professional harness builders worldwide, offering IP67 sealing, lightweight aluminium shell construction, and bayonet coupling in a compact body. The 79-way high-density configuration is suited to primary ECU connectors, full vehicle harness main bulkhead junction points, and complex data acquisition interfaces.
Souriau 8STA — Professional Motorsport Circular Connector
The 8STA series was designed specifically for motorsport and high-performance vehicle harness applications: lightweight hard-anodised aluminium shell, bayonet quarter-turn coupling for rapid engagement under race conditions, IP67 sealing in the mated condition, and a wide temperature operating range. These characteristics distinguish the 8STA from both standard circular mil-spec connectors and general-purpose automotive connectors, making it the benchmark for professional circuit-level motorsport harness connections at ECU interfaces, data acquisition system connectors, and sensor cluster bulkheads.
Mount Type — Inline Plug
The 8STA6-20-35SN is a cable-to-cable or cable-to-panel inline plug, suited to large shell for high circuit-count harness junction applications. The inline format provides a cable-to-cable or cable-to-panel connection point without requiring a panel cutout.
Keyway — N keyway (neutral / no polarisation key)
The N keyway is the standard unpolarised configuration, allowing mating in any rotational orientation when connector polarity is managed by pin assignment and colour coding rather than physical keying.
Contact Type — Socket (Female)
Socket (female) contacts are typically wired to the chassis, panel, or harness side, providing mechanical protection for recessed contact faces when unmated.
