Zirconia oxygen sensor ZS-ST-11

electrochemicalvoltage output4-wire

Cubic ZS-ST-11 is a mini-type zirconia oxygen sensor designed on the basis of HTCC technology, which adopts zirconia as its sensing element to detect the amount of oxygen in motorcycle exhaust systems. Cubic ZS-ST-11 features a flat multilayer ceramic element, which is produced through HTCC process, and an optimized electrode design that enables the sensor to deliver fast response (light-off time <15 seconds) and excellent stability. Cubic ZS-ST-11 is capable of operating within 12–14 V, with a maximum current of 1 A, and withstanding exhaust gas temperatures up to 850°C. The control element of Cubic ZS-ST-11 is protected by a thermal-shock protection (TSP) layer, ensuring reliable operation under high-temperature, high-humidity, and harsh environmental conditions. Cubic ZS-ST-11 provides standard voltage signal output for seamless ECU closed-loop control. With an advanced chip and broad coverage across multiple motorcycle models, Cubic ZS-ST-11 is widely applied in motorcycle manufacturing, maintenance and retrofitting, as well as environmental compliance testing. - Zirconia electrochemical technology with HTCC process. - Multilayer planar ceramic structure with TSP coating. - Precise measurement and high signal resolution enabled by advanced chip design. - TSP coating resistant to violent engine vibration, dust, and moisture. - Suitable for nearly all EFI motorcycle models on the market, ideal for OEMs, aftermarket modifications, and service applications. - Test Temperature: ≤850°C - Operating Voltage: 13±1V - Heater Resistance (Cold State): 17±3Ω - Rich-Burn Voltage (λ=0.93-0.97): ≥750mV - Lean-Burn Voltage (λ=1.05-1.10): 50±30mV - Internal Resistance: ≤1000Ω - Response time (600mV—300mV): <180ms - Response time (300mV—600mV): <180ms - Ignition Time: <15s - Thread Size: M12×1.25
