SGD43S-M3-S7

SGD43S-M3-S7 is a SGD4x series of A2L refrigerant detection product, specifically designed for the HVACR industry as a complete refrigerant detection system (RDS). It is based on the thermal conductivity 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 are enabled by a status-indicating LED for quick visual feedback. With its fast response time and broad compatibility with A2L refrigerants due to its versatile multi-refrigerant calibration, it is an essential component for both residential and commercial HVACR systems. The SGD43S-M3-S7 ensures effective leak detection and complies with stringent industry standards, including UL 60335-2-40 and UL 60335-2-89. The single unit is triple calibrated for R-454A, R-454C and R-455A in refrigeration applications.
