R32 Leak Detection with Open Collector Output
The Figaro FCM2630-J0A, from a world leader in gas sensor innovation, is a compact, factory-precalibrated gas sensor module specifically designed for reliable R-32 (A2L) refrigerant leak detection in air conditioning and refrigeration systems. Featuring the highly selective TGS2630 semiconductor sensor with built-in filter, this module provides excellent resistance to interference gases such as alcohol and other VOCs, significantly reducing false alarms while maintaining high sensitivity to R-32.
With built-in temperature compensation and open-collector outputs for monitoring, alarm, and malfunction signals, the FCM2630-J0A enables straightforward integration into control boards and alarm circuits without complex external components. The convenient connector design allows quick module replacement for periodic maintenance, while the robust semiconductor structure ensures outstanding resistance to mechanical shock and vibration.
Fully compliant with the latest IEC60335-2-40 Edition 7.0 Annex LL and JRA4068:2023 (Performance 3) standards for R-32, this module delivers the safety and performance required for modern A2L refrigerant systems.
Cost-effective, reliable, and easy to implement, the FCM2630-J0A is an ideal solution for manufacturers and installers seeking a standards-compliant, low-maintenance refrigerant leak detection module that combines high selectivity with simple alarm output functionality.
