Sumitomo 6185-0862 1-Way Female RS Sealed Connector

The Component: Genuine Sumitomo high-performance sealed female receptacle connector plug housing. RS Sealed Series taxonomy / 1-position single-cavity female casing / Standard Keying Profile (Dark Gray / Premium Heat-Stabilized PBT / Sealed Waterproof / 1-Way Inline Harness Plug / Component Variant Alias: 6185-0862 / Global Order Reference: 61850862).

Applications & Fitment: Engineered as a premium, high-reliability original equipment (OE) wire-to-wire or wire-to-device waterproof connection plug designed explicitly for low-pole, high-vibration automotive powertrain environments and chassis systems. This 1-pin female plug block is an absolute wiring loom staple across modern Japanese passenger cars, heavy fleet commercial platforms, and powersports networks—prominently integrated within Toyota, Lexus, Honda, Nissan, and Mitsubishi factory wiring architectures. It is standardly deployed across critical single-circuit automotive lines including oil pressure switches, coolant temperature senders, single-tone horn modules, and select air conditioning compressor clutch triggers. It features an integrated top-mounted mechanical thumb locking latch that clicks firmly over the mating male shroud's retention ramp, ensuring a low-tolerance, positive lock that eliminates terminal back-out under severe engine block thermal cycles and multi-axis vibrations. Engineered to meet strict tier-1 factory validation guidelines, its internal single-cavity profile pairs with high-elasticity wire seals to form an absolute barrier against high-pressure moisture ingress, road spray washdowns, salt crusting, and under-hood oil vapors. Highly vulnerable to thumb latch fracturing if field technicians apply rough leverage with un-profiled workshop screwdrivers instead of smoothly depressing the central release lever.
