TE Connectivity 1488991-6 3-Way Female MCON Connector

The Component: Genuine TE Connectivity MCON 1.2mm Sealed Series high-performance 3-way female receptacle connector housing. Engineered with integrated CPA (Connector Position Assurance) mechanism / 3-position single-row linear layout / Coding-B Polarization Profile (High-Impact Black and Natural PA66-GF35 Glass-Reinforced Nylon Body with Red CPA Latch / IP67 Weatherproof Rated / Automotive Sensory and Actuator Loom Plug / Component Part Number: 1488991-6 / TE Internal Reference: 1488991-6).

Applications & Fitment: Engineered to withstand the relentless mechanical harmonics and environmental extremes of modern automotive powertrain, chassis, and under-hood sensory networks. This genuine 3-pin MCON series female socket assembly is an essential component for high-reliability harness builds, sensor lead repairs, and performance engine management retrofits across major European and global vehicle platforms. It is widely utilized for wire-to-wire, wire-to-board, and wire-to-device connections, typically pinning critical engine bay hardware such as camshaft position sensors, pressure transducers, small actuator links, and electronic lighting infrastructure. The housing is molded from premium PA66-GF35 material, granting it exceptional resilience against high thermal deflection, automotive chemical exposure, and intense vibration cycles up to a maximum continuous operating ceiling of 125°C. For absolute installation security, it features an integrated secondary Terminal Position Assurance (TPA) lock alongside a prominent red mechanical Connector Position Assurance (CPA) slide lock. The CPA prevents accidental unmating from severing critical signal feeds due to road debris impacts or severe physical shaking. Its internal cavities are designed with a 4.00mm pitch centerline to house and insulate standard MCON 1.2mm clean-body female box terminals, forming an absolute weather-tight barrier against high-pressure washdowns, salt spray, and moisture ingress when paired with single-wire rubber cable seals. An indispensable component for specialized auto-electrical workshops, professional motorsport wiring technicians, and tier-1 harness manufacturers.
