Refrigerant gas refrigerant gas sensor AM4206

NDIRfor leak detection

Cubic AM4206 is an automotive R290 refrigerant leakage monitoring sensor based on Non-Dispersive Infrared (NDIR) technology, specifically designed for detecting R290 gas leaks in automotive HVAC systems. AM4206 can continuously monitor R290 refrigerant leaks in real-time and promptly generate alarm signals via LIN communication. Based on reliable dual-beam design and smart auto baseline mechanism, AM4206 can achieve long-term stability, rapid detection and less gas cross interference, providing an effective and robust solution for safety monitoring, in response to the implementation of EU F-gas Regulation.
