HEATAN™ Sensor Feedthroughs

Enabling simpler sensor designs for ultra-high temperature applications

HEATAN™ high-temperature sensor feedthroughs from SCHOTT perform reliably in extreme conditions, including temperatures of 1000°C (1800°F) and above. Made using a unique material combination and sealing technology, they enable the development of next-generation sensor designs.

Surpassing high-temperature challenges with less components

HEATAN™ sensor feedthroughs are a single-component solution for applications of 1000°C (1800°F) and beyond. While conventional sensor sealing assemblies are based on multi-component designs requiring several manufacturing steps to achieve the required high temperature properties, our customizable and easy-to-integrate sensor feedthroughs can be assembled using a simple sealing process.

The reduced number of components and process steps means a significant reduction in our customer’s internal engineering and purchasing efforts, benefitting from a simple and economical “fit & forget” or drop- in replacement solution.

SCHOTT HEATAN™ sensor feedthroughs can be custom-designed according to specific requirements.

The superior qualities of SCHOTT’s high-temperature sensor feedthroughs are suitable for all heat-exposed automotive sensors, particularly in engine- management systems and exhaust-treatment technologies, such as temperature sensors, gas sensors, chemical property sensors, pressure sensors, particulate matter sensors.

Unique glass-ceramic technology offers superior high-temperature & corrosion robustness

By integrating feedthroughs from SCHOTT into high-temperature sensor designs, customers benefit from excellent temperature & corrosion resistance:

Superior mechanical stability

in operating environments of 1000°C (1800°F) and above

Temperature cycling

for up to 300.000 km (180,000 miles)

Corrosion resistance

to diesel / gasoline exhaust gas and chemicals, e.g. AdBlue

Combining the advantages of glass and ceramics

SCHOTT’s revolutionary glass-ceramic sealing technology combines the best of both material worlds: the“glassy” part of the material enables a direct seal with metal or ceramics. The “ceramic” part gives it the high-temperature edge.

Glass-

During the “glassy phase” of the sealing process, the glass-ceramic sealant can form a direct seal with ceramic substrates or metal conductor pins. Direct sealing means that an extended creepage distance can be achieved without any additional interface or soldering materials. This increases the reliability of the seal considerably.

Ceramic

The subsequent “ceramization phase” of the sealing process leads to superior mechanical stability at extreme temperatures. In comparison to other sealing materials (typically used in applications from -40°C up to 300°C), glass-ceramic sealing offers superior gas-tight insulation even at very high operating temperatures from 300°C upwards and peak temperature of higher than 1000°C (1800°F) and/or in extreme harsh environment conditions (e.g. exhaust fumes).
