TE Connectivity 1801176-4 2-Way Female Sealed Connector (Yellow)

The Component: Genuine TE Connectivity high-performance sealed female socket receptacle connector housing. Sensor Flat Contact System taxonomy / 2-position single-row linear female casing / Keying Code 4 (Distinct Yellow / Premium Glass-Reinforced PBT / Sealed Waterproof / 1x2 Layout / Female Inline Sensor Plug / Component Variant Alias: 1801176-4 / Global Order Reference: 1801176-4 / HPSL Series System).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-wire waterproof connection plug designed explicitly for harsh, high-exposure vehicular sensor and telemetry environments. This 2-pin female socket receptacle block is a heavy-duty wiring harness staple across modern passenger vehicles, commercial machinery, and agricultural equipment platforms—frequently integrated for high-vibration chassis nodes, powertrain sensor networks, fluid temperature monitors, and exhaust management telemetry links. It features an integrated mechanical mating alignment structure with strict Code 4 physical keying safeguards that guarantee flawless orientation with the matching male header side. Engineered to survive severe environmental conditions, its fully sealable architecture delivers an absolute barrier against high-pressure moisture ingress, continuous road salt exposure, fine dust penetration, and under-hood fluid films. Highly vulnerable to terminal guide damage or primary latch arm stress fracture if field service technicians attempt forced maintenance extraction using un-profiled hand tools rather than standard micro-terminal release keys.
