Cummins engine spare parts vehicle speed sensor CC000477

Built as a critical data source for vehicle control systems, this speed sensor features a Hall-effect sensing core for ultra-precise speed detection. It achieves a measurement range of 0-250km/h with a resolution of 0.1km/h and a signal error of ≤0.5%, ensuring real-time transmission of accurate speed data to the ECU. The sensor’s magnetic circuit design (neodymium permanent magnet + optimized air gap) enables it to detect rotational speeds as low as 1rpm, supporting smooth starting and gear shifting for AMT (Automated Manual Transmission) systems. For Cummins ISX15-powered long-haul trucks, this precision ensures the adaptive cruise control (ACC) maintains a stable following distance, reducing driver fatigue and collision risks

Engineered to endure the harsh mechanical environment of heavy-duty vehicles, the CC000477 sensor adopts a rugged structural design. The housing is made of impact-resistant PA66-GF30 (glass fiber-reinforced nylon) with a tensile strength of 280MPa, resisting deformation from accidental impacts and engine vibration. The sensing probe features a stainless steel (304 grade) protective sleeve, preventing damage from road debris and metal shavings. A reinforced cable (TPE sheath + tinned copper conductor) with a tensile strength of 100N ensures reliable signal transmission even under repeated bending (10,000+ cycles). This robust construction ensures the sensor maintains performance during off-road driving, construction site operations, and long-haul transportation

Optimized for diverse operating climates and working conditions, the sensor exhibits exceptional environmental resistance. It operates stably within a temperature range of -40℃ to 125℃, adapting to frigid northern winters (cold starts at -35℃) and high-temperature desert environments (engine compartment temperatures up to 110℃). The sensor achieves an IP68 protection rating (per IEC 60529), completely blocking dust ingress and withstanding temporary submersion in 1.5m of water—ideal for rainy or flooded road conditions. The connector uses HNBR rubber seals, resisting corrosion from road salt and chemical contaminants, and passes 1500-hour neutral salt spray testing (ASTM B117) with no signal degradation

The CC000477 speed sensor plays a key role in coordinating multiple vehicle systems, enhancing performance and reducing maintenance costs. Accurate speed data enables the ECU to optimize fuel injection timing, reducing fuel consumption by 3-5% for Cummins-powered trucks. It synchronizes with the ABS and ESC systems, triggering anti-lock braking within 0.01s during emergency stops to prevent skidding. The sensor’s long service life (≥200,000km) and low failure rate (≤0.1% per 100,000km) minimize replacement frequency, while its OE compatibility avoids signal mismatches that cause instrument cluster errors or ECU malfunctions (repair costs up to $1,500). Backed by a 2-year/250,000km Cummins warranty, it provides reliable support for fleet operations and reduces unplanned downtime
