Using a miniaturized planar sensor element and integrated signal conditioner, this sensor delivers fast response (T90 < 180ms) and high accuracy (±3.5% of reading) across a 0-1,500 ppm NOx range. The 32mm diameter housing and simplified wiring harness enable easy integration into tight engine compartments, making it ideal for compact cars, delivery vans, and hybrid powertrains.
Miniaturized Design Advantages
Space-Efficient Layout: 40% smaller than legacy sensors, fitting into engine bays with <50mm radial clearance.
Low Power Heater: 1.5W heating element reduces energy consumption by 25% compared to standard sensors, beneficial for start-stop and hybrid systems.
Gasoline Engine Optimization
Lambda-Insensitive Measurement: Accurate NOx readings across stoichiometric (λ=1) and lean-burn (λ>1) conditions, supporting gasoline direct injection (GDI) engines.
Fast Light-Off: Reaches operating temperature in 75 seconds, minimizing unmonitored NOx emissions during cold starts.
Reliability & Durability
Moisture Resistance: IP67-rated connector and silicone-sealed sensor body prevent water ingress in high-humidity environments.
Thermal Cycle Stability: Passes 10,000 cycles of -40°C to 800°C thermal shock testing, ensuring long-term reliability.
Electrical & Diagnostic Features
Single-Wire CAN Interface: Reduces wiring complexity with 250 kbps data transmission, compatible with entry-level ECUs.
Self-Compensating Algorithm: Automatically adjusts for sensor drift using built-in reference cells, eliminating the need for periodic recalibration.
Light-Duty Vehicles:
Subcompact cars (1.0-1.6L GDI engines): Ensures compliance with Euro 7’s RDE NOx limits (≤80 mg/km) in real-world driving.
Hybrid electric vehicles (HEVs): Accurate NOx measurement during engine operation in mild and full hybrid systems.
Commercial Vans:
Small delivery vans (3.5T GVW): Optimizes NOx aftertreatment in downsized turbocharged gasoline engines.
Power Equipment:
Portable generators (1-10 kVA): Meets EPA Tier 4 Final NOx standards for recreational and industrial generators.
Q: Does the compact size affect measurement accuracy?
A: No, the miniaturized sensor element uses the same planar technology as full-size models, maintaining ±3.5% accuracy across the range.
Q: Can it be installed upstream or downstream of the catalytic converter?
A: Designed for upstream installation (before the TWC); downstream use requires a separate ammonia sensor for SCR systems.
Q: What is the warranty period?
A: 3-year/60,000-mile warranty covering sensor drift and manufacturing defects under normal use.
Q: Is the sensor compatible with ethanol-blended fuels (E10, E20)?
A: Yes, validated for use with up to E20 ethanol blends—no performance degradation in oxygenated fuels.
