Hirschmann 805-122-541 4-Way Female SealStar 1.2 Connector

The Component: Genuine Hirschmann high-performance sealed female socket connector plug housing. SealStar 1.2 Series taxonomy / 4-position single-row linear female casing / Code A Keying Profile (Solid Black with Code A Shroud / PA66 GF25 / Sealed / 1x4 Grid Configuration / Female Inline Interface Plug / Component Variant Alias: 805-122-541 / Global Order Reference: 805122541 / BMW Cross-Reference: 7549032-02 / 7 549 032-02 / Mercedes-Benz Cross-Reference: A2115451928 / A 211 545 19 28).

Applications & Fitment: Engineered as a premium, compact original equipment (OE) wire-to-device waterproof connection plug designed to protect critical low-voltage signal paths in high-stress vehicle environments. This 4-pin female socket block is an established high-density harness staple across premium German passenger car frameworks—notably serving as an identical factory match for high-exposure BMW and Mercedes-Benz powertrain, exterior lighting, and chassis networks. It is widely specified across space-constrained zones for advanced LED headlight ballast assemblies, high-precision oxygen sensors (lambda probes), ride-height leveling units, and complex park assist sensors. It features an integrated Connector Position Assurance (CPA) locking mechanism that physically blocks the main locking lever from backing out under intense, multi-axis engine vibration or structural chassis harmonics. Built to conform to demanding LV214 and VDA validation guidelines, it provides an absolute environmental barrier against high-pressure steam washdowns, winter road salt, and fluid spray. Highly vulnerable to integrated thumb-latch fracture or inner alignment keyway damage if technicians attempt forced service extractions without cleanly disengaging the secondary locking safety slide first.
