Original Bosch 1928498056 Terminal

The Component: Genuine Bosch high-performance female receptacle crimp socket terminal. BDK 2.8 Series taxonomy / 2.8mm contact system / Damping variant / Tin-plated CuNiSi construction (F-Crimp / Sealed-Application Grade / Component Alias Code: 1928498056 / Global Order Reference: 1-928-498-056).

Applications & Fitment: Engineered as a premium, vibration-damping electrical contact explicitly designed for harsh, fluid-exposed automotive and commercial transport wiring looms. This terminal is the foundational 2.8mm female receptacle for the Bosch Kompakt 4 (Compact 4) interconnect family, extensively integrated within precision European diesel injection wire harnesses, heavy-duty transmission solenoids, and demanding powertrain telemetry modules. Its specialized BDK interior design features internal spring contact zones that maintain reliable mechanical tension against mating pins despite intense, multi-axis engine vibration, preventing critical fretting corrosion. When properly combined with an individual single-wire silicone seal (SWS), it blocks out aggressive moisture, salt spray, and oil vapors in severe-duty operational zones. Highly vulnerable to terminal pull-out or erratic circuit dropouts if crimped using incorrect hand tools; requires a calibrated automotive crimping tool to properly establish the specific F-crimp contact profile and roll down the rear insulation/seal wings securely.
