The SGD48S-M3-S8 is part of our SGD4x series of A2L and A3 refrigerant detection products, specifically designed for the HVAC industry as a complete refrigerant detection system (RDS). It is based on the photoacoustic NDIR measurement principle and features a dual contact relay output that can trigger a signal relay to start a blower, switch off the load or warn a control board. Easy integration and installer-friendly feedback is enabled by a status-indicating LED for quick visual feedback.
With its fast response time to R290, it is an essential component for residential and commercial HVAC systems and other applications. The SGD48S-M3-S8 ensures effective leak detection and complies with stringent industry standards, including EN IEC 60730-1, IEC 60335-1 and IEC 60335-2-40.
