8STA6-22-35PN — 100-Way Souriau 8STA Inline Plug Motorsport Connector (Pin (Male), N keyway (neutral / no polarisation key))

The 8STA6-22-35PN is a 100-way Souriau 8STA series cable-to-cable or cable-to-panel inline plug connector with pin (male) contacts and N keyway (neutral / no polarisation key). The red shell colour provides immediate visual identification of this connector within a multi-connector harness assembly. The Souriau 8STA series is the professional motorsport circular connector standard used by factory racing teams, OEM motorsport divisions, and top-level professional harness builders worldwide. It is found on FIA World Championship, GT, endurance, and rally vehicle harnesses where connector reliability under extreme vibration, thermal cycling, and fluid exposure must be guaranteed throughout a competition season. The 100-circuit configuration is among the highest-density formats in the 8STA range, suited to primary ECU connectors, full vehicle harness main bulkhead junction points, and complex data acquisition system interfaces.

Souriau 8STA — The Professional Motorsport Connector Standard

The Souriau 8STA series was developed specifically for motorsport and high-performance vehicle harness applications, addressing limitations in both standard circular mil-spec connectors and general-purpose automotive connectors. Key design features include a lightweight aluminium alloy shell with hard-anodised or plated finish for corrosion resistance, a bayonet coupling mechanism for rapid single-hand engagement and disengagement, IP67 environmental sealing in the mated condition, and a wide operating temperature range covering the full spectrum of motorsport under-bonnet and chassis environments. The 8STA connector’s combination of performance, weight, and reliability makes it the benchmark against which other motorsport connector systems are measured.

Shell Size and Circuit Count

The 8STA6-22-35PN uses size 22, which is very large shell for maximum circuit-count main harness bulkhead applications in the 8STA range. The 100-circuit configuration is among the highest-density formats in the 8STA range, suited to primary ECU connectors, full vehicle harness main bulkhead junction points, and complex data acquisition system interfaces. The shell size determines the available insert arrangements and maximum circuit count — always verify that the shell size and insert layout are correctly specified against the harness design schematic before ordering contacts or backshell accessories.

Keyway — N keyway (neutral / no polarisation key)

The N keyway is the standard unpolarised configuration. It allows the connector to be mated in any rotational orientation without mechanical keying, which is used when connector polarity is managed by pin assignment and colour coding rather than physical keying. In professional harness builds, selecting the correct keyway for each connector position on a multi-connector device prevents the most common installation error in motorsport harness work: connecting a harness sub-loom to the wrong connector on an ECU, PDM, or data logger during quick-turnaround installation under race conditions.

Contact Type — Pin (Male)

Pin (male) contacts are typically used on the device or cable plug side of the connector pair. Appropriate dust caps should be used to protect exposed pin contacts during unmated storage and transport between service intervals.
