Introduction
Cubic switch type oxygen sensor ST is also called as four-wire oxygen sensor, it is a planar 2-state λ=1 sensor of ZrO2 (Nernst-principle) with an integrated heater. The sensor contains 4 wires, in which two wires are for heaters, the other two wires are for transmitting voltage signals.
Features
1.Independent R&D and production of chips
2.Short light-off time
3.Low heating power
4.Less dependent on exhaust temperature (conducive to the stability in different operating situations)
5.Double protection on the top of tube to confront impact
6.Good aging resistance
7.Anti-coating and anti-poisoning
8.Compact structure (high anti-vibration level)
9.Longer duration
10.Independent R&D and production for ceramic/zirconia oxide ZrO2 chips
11.Covering multiple series of car models.
12.Strong ODM/OEM capacity, cover multiple series of car models
