8STA0X-06-35SN — 5-Way Souriau 8STA Flange/Panel Mount Motorsport Connector (Socket (Female), N keyway (neutral / no polarisation key))

The 8STA0X-06-35SN is a 5-way Souriau 8STA series panel or bulkhead flange-mount receptacle connector with socket (female) contacts and N keyway (neutral / no polarisation key). The yellow 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. With 5 circuits, this connector is ideal for dedicated single-function interfaces — sensor-to-ECU point-to-point circuits, single actuator feeds, or compact sub-harness breakout points where a low circuit count in a sealed motorsport connector is the design goal.

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 8STA0X-06-35SN uses size 06, which is medium shell suited to mid-range circuit-count sensor and ECU interfaces in the 8STA range. With 5 circuits, this connector is ideal for dedicated single-function interfaces — sensor-to-ECU point-to-point circuits, single actuator feeds, or compact sub-harness breakout points where a low circuit count in a sealed motorsport connector is the design goal. 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 — Socket (Female)

Socket (female) contacts are used on the chassis, panel, or harness side of the connection in most motorsport harness conventions, providing mechanical protection for the recessed contact faces when the connector is unmated during service.
