SGD4x A2L Refrigerant Sensors

Sensirion SGD4x A2L Refrigerant Sensors are Refrigerant Detection Systems (RDS) designed for HVACR applications. The Sensirion SGD4x sensors operate on the thermal conductivity principle and include a dual dry-contact relay output to trigger a blower, shut off the load, or alert a control board. An LED status indicator provides quick visual feedback for easy installation. With fast response times and multi-refrigerant calibration, the devices support A2L refrigerants, making them ideal for residential and commercial systems.
