Hirschmann 805-031-551 8-Way Female SealStar 1.2 Connector (Mercedes A0265455926)

The Component: Genuine Hirschmann high-performance sealed female socket connector plug housing. SealStar 1.2 FA Series taxonomy / 8-position dual-row linear female casing / Code A Keying Profile (Solid Black / PA66 GF25 / Sealed / 2x4 Grid Configuration / Female Inline Interface Plug / Component Variant Alias: 805-031-551 / Global Order Reference: 805031551).

Applications & Fitment: Engineered as a premium, compact original equipment (OE) wire-to-device waterproof connection plug designed to meet the rigorous physical and environmental demands of modern automotive and commercial vehicle electronics. This 8-pin female micro-terminal socket block is an established high-density harness staple across European passenger vehicle frameworks—frequently specified for space-constrained, high-vibration applications such as electronic throttle bodies, headlight cluster distribution links, steering column multi-switch modules, and complex engine bay sensor networks. It features an integrated red Connector Position Assurance (CPA) locking slide that prevents mechanical decoupled drift caused by intense, multi-axis engine vibration or chassis harmonics. Built to deliver an absolute environmental barrier against moisture ingress and particulate dirt, it reliably isolates delicate low-voltage logic paths from oil vapors, salt-crusted road spray, and aggressive engine compartment cleaners. Highly vulnerable to top-mounted locking tab fracture or internal terminal alignment rail warping if field service technicians roughly force extraction using un-profiled hand tools rather than standard low-taper secondary lock release methods.
