Original Cummins engine spare parts position sensor C5594275

Built as a critical data source for engine timing and fuel control, this position sensor adopts a non-contact Hall-effect design for ultra-precise detection. It measures camshaft or crankshaft position with a resolution of 0.1° crank angle and a signal error of ≤0.3%, ensuring real-time transmission of accurate position data to the ECU. The sensor’s optimized magnetic circuit (neodymium magnet + high-sensitivity Hall element) enables reliable detection even at low engine speeds (≥50rpm), supporting smooth cold starts and precise fuel injection timing. For ISB6.7 engines, this precision ensures the ECU adjusts injection duration and timing dynamically, maximizing combustion efficiency and reducing fuel consumption by 5-7% compared to low-quality sensors

Engineered to endure the harsh mechanical environment of mid-range engines, the C5594275 sensor features a rugged construction. 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 (10-2000Hz). The sensing probe is protected by a 304 stainless steel sleeve, preventing damage from metal shavings and coolant splashes. A reinforced cable (TPE sheath + tinned copper conductor) with a tensile strength of 150N ensures reliable signal transmission even under repeated bending (15,000+ cycles). The sensor’s compact design (65mm length, 25mm diameter) fits seamlessly in tight engine compartments without interfering with adjacent components

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 engine compartments (up to 110℃). The IP67 protection rating (per IEC 60529) completely blocks dust ingress and withstands temporary submersion in 1m of water—ideal for construction machinery exposed to mud and rain. The connector uses HNBR rubber seals and gold-plated pins, resisting corrosion from road salt and chemical contaminants, and passing 1500-hour neutral salt spray testing (ASTM B117) with no signal degradation

The C5594275 position sensor plays a key role in coordinating multiple engine systems, enhancing performance and reducing maintenance costs. Accurate position data enables the ECU to synchronize fuel injection with valve timing, reducing unburned fuel and particulate emissions to meet China VI and EPA Tier 4 standards. It supports the engine’s start-stop function by quickly detecting crankshaft position, reducing battery drain during frequent stops (common in city buses). The sensor’s long service life (≥200,000km) and low failure rate (≤0.2% per 100,000km) minimize replacement frequency, while its OE compatibility avoids signal mismatches that cause ECU malfunctions (repair costs up to $1,800). Backed by a 2-year/250,000km Cummins warranty, it provides reliable support for mid-range engine operations and reduces unplanned downtime
