SAAF series

Making cars more efficient often goes hand in hand with improving driving experience. The anti-fogging / auto-defrost sensor maximizes the comfort and safety of passengers by improving visibility while also reducing the amount of energy required to defog and defrost car windshields. It measures relative humidity and temperature on the inside of the windshield, enabling the HVAC system to actively prevent fogging.

Features and benefits

 

The SAAF series is designed for seamless integration and long-term reliability, ensuring optimal performance in automotive HVAC systems. With a flexible installation process, it can be mounted using either brackets or tape, allowing for easy adaptation to different vehicle designs and reducing installation complexity. Its small footprint enables optimal placement for maximum system performance in the densely populated area near the rear-mirror socket, while its angled connector ensures seamless assembly on the manufacturing line.

 

Built to withstand demanding conditions, the sensor features automotive-grade connectors that ensure durability and consistent performance, even in harsh environments. These connectors can also be customized in-house to meet specific customer requirements, providing a tailored solution without compromising reliability.

 

The sensor delivers highly accurate, linearized, and temperature-compensated signals, enabling the HVAC control system to make precise adjustments for maintaining an optimal cabin climate. With fast response times, it quickly adapts to environmental changes, providing real-time data to support efficient and responsive climate regulation.
