Product Name : Thimble Oxygen Sensor - OS Series
Product Description
What is a Thimble Oxygen Sensor?

A Thimble Oxygen Sensor is a switch type oxygen sensor for detecting oxygen contents. Its ceramic sensing cell is pressed formed to cone shape, hence “Thimble”. It is a more traditional type oxygen sensor and generally comes in 1 or 4 wires.

CERADEX's patented single cell thimble technology enables our sensors to be more resistant to the harsh environment of the exhaust system, by adding an extra specialized protective coating to the ceramic cell surface, resulting in longer sensing lifespan. To ensure the highest quality and stability, every piece of sensor manufactured undergoes strict simulated bench for function check of lambda voltage output, as well as pressurized sealing bench for leakage check. With 25 years of experience in the field, choose CERADEX's Thimble Oxygen Sensor for your replacement needs.
