FAQ

A planar ceramic heater for oxygen sensors is a high-performance heating component designed to provide quick ignition time, strong resistance to high temperatures and poisoning, and excellent high-temperature insulation (≥1MΩ at 800℃). It ensures the oxygen sensor reaches its operating temperature rapidly (light-off time ≤12s), which is essential for low pollutant emissions and fuel economy. Its main applications include:
– Automobile engine management systems and motorcycle exhaust after-treatment.
– Thermal surface igniters and hot air generation tools.
– Chemical analysis, laboratory equipment, and environmental monitoring systems.

Planar ceramic heaters are available in four main configurations: Conventional Switch Type, XF Pump Current Type, Air-Fuel Ratio Type, and Five-Wires Wide Range Type.
The main differences between the Conventional and XF Pump Current types lie in their electrical specifications:
– Operating Voltage: Conventional types operate at 1214V, while XF Pump Current types operate at a lower 79V.
– Heater Resistance: Conventional types feature a resistance of 9±1.5Ω, whereas XF types feature 3.0±0.5Ω.
– Response Time (300mV~600mV): At 800℃, the XF Pump Current type has a faster Poor-to-Rich response time (≤60ms) compared to the Conventional type (≤100ms). Both guarantee a long lifetime and high three-point bending strength (≥400MPa).
