Planar Oxygen Sensor

Faster startup and response time

Planar oxygen sensor also known as narrowband O2 sensor, is a switch type lambda sensor that detects air to fuel ratio in binary format. The ceramic sensing element is monolithic stacked design, hence "planar". With integrated heating element, known as heated oxygen sensor, makes it faster to reach operational temperature, which result in lowering emission during start up time. The planar oxygen sensors generally come in 3 or 4 wires and covers most of the vehicle today.

Planar lambda sensor function as rich and lean indicator. With planar structured ceramic element, Planar O2 sensors have a faster response time than conventional oxygen (O2) sensors, allowing the vehicle's ECU (Electronic Control Unit) to manage fuel injection rapidly and sustain ideal fuel economy.

Ceradex's patented single-cell planar technology enables our sensors to achieved faster startup time and shorter response time that reflect more accurate lambda readings.
