Sumitomo 6187-3231 MT Sealed Series 3-Way Male

The Component: Genuine Sumitomo 6187-3231 3-way automotive sealed connector housing. MT Sealed 2.3mm (090) Series 3-position 2-row male pin tab inline cap shroud casing (Natural White / PBT / Sealed / Cable Mount Inline Cap / Mating Tab Width 2.3mm / Component Alias: 61873231).

Applications & Fitment: Designed as a primary factory original equipment (OE) harsh-environment connection solution for low-voltage power and critical signal automotive telemetry. Extensively specified across prominent global Japanese motorcycle and passenger car platforms (including heavy deployment across Yamaha, Suzuki, and Kawasaki wiring grids) as the definitive male inline interface for camshaft position sensors, crank angle sensors, fuel pumps, gear position indicators, and motorcycle side stand switch runs.

Engineered to maintain complete electrical continuity under brutal powertrain harmonic vibration and direct high-pressure road wash. Highly vulnerable to integrated alignment tracking channel distortion if forced blindly against misaligned female socket plug partners during field workshop diagnostics, or internal rear matrix seal tearing if lines are manipulated using non-standard extraction tools.
