The Sensata MGD series of refrigerant leak detection sensors delivers a compact embedded module which is optimized to meet demanding OEM requirements and be easily designed into HVAC & Refrigeration Equipment with an integral connector.

Featuring the innovative Speed of Sound technology with high accuracy and fast response times, the MGD series is compatible with R32, R454 series, and R455 series refrigerants, including systems which can detect any of 2 or 3 refrigerants with the same part number - simplifying inventory and engineering processes.

As with all Sensata Resonix™ sensors, the MGD series offers superior resistance to overexposure and poisoning, high temperature (working temperatures up to 105 °C) and humidity resistance, and a lifetime greater than 15 years with no need to calibrate - making the MGD the ideal leak detection component for A2L HVAC&R systems

This factory-set sensor designed specifically for UL60335-2-40 delivers fast response times and low power consumption, requires no re-zeroing or field calibration, and is targeted for R32 and R454B refrigerants.
