Kostal 09441382 3-Way Female SLK 2.8 Coding B Connector

The Component: Genuine Kostal high-performance sealed female receptacle connector plug housing. SLK 2.8 Sealed Series taxonomy / 3-position single-row female casing / Mechanical Coding B Profile (Jet Black Housing Shell / Premium Heat-Stabilized PBT / Sealed Waterproof / 1x3 Grid Layout / Female Sensor and Device Plug / Component Variant Alias: 9441382 / Global Order Reference: 09441382).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-wire or wire-to-device waterproof connection plug designed explicitly for harsh under-hood environmental conditions and high-vibration engine monitoring systems. This 3-pin female housing is an absolute wiring loom staple across prominent European vehicle platforms—extensively integrated within BMW and Mercedes-Benz engine networks. It is standardly deployed across critical single-row vehicle monitoring runs, most notably serving as the primary factory connector interface for engine oil level sensors (frequently cross-referenced with BMW OE part numbers 12521433915 and 1433915), camshaft position sensors, and select heavy-duty crankshaft monitoring modules. It features an integrated white mechanical secondary side-locking slide rail mechanism (Sidelock) that snaps into place after terminal loading to provide positive terminal position assurance (TPA), alongside an integrated top-mounted thumb latch clip that ensures a secure, low-tolerance interface over the mating device header's retention ramp. Engineered to conform to rigid tier-1 European factory validation guidelines, its internal cavities pair with individual single-wire seals to form an absolute barrier against high-pressure moisture ingress, severe road spray washdowns, salt misting, and hot engine oil vapors. Highly vulnerable to white side-locking rail fracturing or slider derailment if field maintenance technicians attempt to pry the mechanism with un-profiled workshop screwdrivers before releasing the primary safety tracks.
