Description
The Johnson Controls GM200-MH00 A2L Refrigeration Sensor is a leak detection component designed to monitor R32 and other A2L refrigerants and provide safety feedback to control systems. It operates on 24V power and uses digital communication for integration with building automation controls. Installed in air conditioning and refrigeration equipment, it continuously detects refrigerant concentration levels to support safe operation and prevent hazardous conditions. This component is applied in HVAC systems as a safety monitoring component that enables leak detection, system protection, and reliable operational control in modern low-GWP refrigerant applications.
