Bosch planar ceramic technology

• Heater layer: Ceramic sheet printed with electrical contacts and the heater pattern itself
• Air duct layer: Creates a void for reference air in the finished assembly
• Sensor Layer: Ceramic sheet with printed layers for the inner (reference air) and outer (exhaust gas) electrodes, as well as electrical contacts and a porous protective layer over the outer electrode to protect it from the corrosive effects of exhaust gases

Bosch thimble ceramic technology

• Base ceramic probe of Zirconium and Yttrium: Forms a tough base that resists cracking from mechanical and thermal shock
• Patented Platinum Power Grid: For optimized sensing, delivering best-in-class performance and maximum service life
• Fine particle filter: Prevents contamination of the electrode for longer service life
• Coarse particle filter: Protects against exhaust gas and other chemical contamination, increasing sensor performance life
