Product Details

Engineering Features	Technical Advantages	Strategic Customer Benefits
High-Grade PA66 GF30 Housing	Reinforced with 30% glass fiber for exceptional thermal and chemical stability.	Extended Service Life: Prevents housing embrittlement even when exposed to 150°C temperatures and aggressive automotive fluids, reducing long-term vehicle failure rates.
30G Vibration Resistance	Engineered with a robust lance-locking system to withstand intense mechanical shock.	Zero Signal Interruption: Ensures consistent electrical contact on engine-mounted sensors and actuators, eliminating “ghost faults” and erratic engine performance in high-vibration zones.
Advanced Radial & Wire Sealing	Features a high-integrity radial seal combined with individual wire seals.	Superior Environmental Protection: Creates a moisture-proof barrier that prevents internal terminal corrosion from oil, coolant, or high-pressure spray, maintaining circuit purity.
Moulded Protective Wall Design	Includes an integrated physical shield around the locking clip.	Mechanical Safeguard: Protects the delicate locking mechanism from external impact and debris build-up, ensuring the connector remains securely fastened throughout its lifecycle.

Q1: Which terminals should I use with the Bosch 1928403876?

A: The 1928403876 is designed for 2.8mm blade width female terminals. We recommend using genuine Bosch 2.8 series or compatible BCI terminals with silver or tin plating depending on your sensor’s conductivity requirements.

Q2: What is the benefit of the 30G vibration rating?

A: A 30G rating is significantly higher than standard automotive connectors. It means the 1928403876 is specifically tested to prevent contact fretting and disconnection even when mounted directly onto high-vibration sources like diesel engines or heavy-duty transmissions.

Q3: Is the brown color just for aesthetic purposes?

A: No. In the Bosch Kompakt 1.1a series, colors represent Mechanical Coding. The brown housing (Code 1) ensures that it only mates with the corresponding brown male header, preventing expensive cross-connection errors during vehicle assembly.
