About

Comprehensive safety with A2L refrigerant sensor

Transitioning to low-GWP alternatives like A2L refrigerant introduces new safety challenges that demand precise monitoring. Infineon offers a comprehensive portfolio designed to address these specific needs. By integrating our sensors, you create a responsive leak detection system capable of triggering immediate mitigation actions; such as activating ventilation fan; to prevent hazardous gas accumulation.

This level of responsiveness is essential for modern HVAC applications, from residential heat pumps to large commercial chillers. Our sensors are also fully qualified for automotive environments, ensuring passenger safety in vehicle air conditioning systems. Whether you are designing for homes, buildings, or the road, our A2L leak detection solutions provide the certified assurance you need to deploy A2L refrigerant technologies with confidence.

XENSIV™ thermal conductivity-based A2L refrigerant sensor

Detect leaks reliably with Infineon’s XENSIV™ TCI-R sensor, a crucial component for modern Refrigerant Detection Systems (RDS). Utilizing the thermal conductivity principle, this advanced A2L sensor offers superior performance compared to traditional detection technologies. Its standout features include ultra-low power consumption and rapid response times, making it the perfect choice for continuous, always-on monitoring in HVAC units.

The XENSIV™ TCI-R is highly versatile, designed to detect a wide spectrum of refrigerants common in today’s residential and commercial systems. It supports key A2L refrigerants, including R32, R454A, R454B, R454C, R455A, and R1234yf.

Safety is paramount in HVAC design. When this A2L sensor identifies a leak, the system can instantly trigger critical safety protocols—such as activating ventilation fans to dilute refrigerant concentration. This automated response significantly enhances occupant safety and ensures your equipment meets strict regulatory compliance standards. Choose XENSIV™ TCI-R for a robust, energy-efficient solution to refrigerant leak detection.

Advanced technology for reliable leak detection

At the heart of our A2L refrigerant family lies advanced thermal conductivity technology. Infineon’s XENSIV™ refrigerant sensors operate using thermal conductivity and a differential MEMS sensor design (Wheatstone bridge), measuring the heat transfer through gases after heating parts of the MEMS structure. This sensing principle ensures that every A2L sensor delivers stable, drift-free measurements over a 15-year lifespan. Unlike traditional methods that may degrade when exposed to certain chemicals, our sensors are highly resistant to poisoning. This durability ensures that your leak detection system remains operational and accurate, minimizing maintenance costs and downtime.

Each sensor arrives factory-calibrated, simplifying the manufacturing process for HVAC equipment makers. The built-in firmware automatically compensates for environmental variables such as temperature, humidity, and pressure, ensuring consistent performance in diverse operating conditions. By choosing Infineon's XENSIV™ TCI-R, you are selecting a technology that makes A2L leak detection not just a compliance checkbox, but a reliable, long-term safety feature.

Streamlined compliance for global markets

Meeting global safety regulations is a complex hurdle for any manufacturer using A2L refrigerant. Our sensor family is engineered to simplify this process. As UL-recognized components according to UL 60335-2-40/89, this pre-certification allows you to bring compliant products to market faster.

Beyond regulatory approvals, our commitment to quality is proven through rigorous testing. The family is qualified for industrial applications according to JEDEC standards and meets AEC-Q100 criteria for automotive use. This means that when you integrate our A2L sensor, you are building your leak detection system on a foundation of proven reliability. Trust Infineon to help you navigate the future of sustainable cooling with safe, compliant, and efficient A2L leak detection solutions.
