Sensirion's "SGD43S-M3-S5" is a robust refrigerant leak detection system designed for HVACR (heating, ventilation, air conditioning, and refrigeration) applications. It utilizes Sensirion's proprietary thermal conductivity technology to achieve high-precision detection for A2L refrigerants (R-32, R-454B). ■ Features - Over 15 years of design life: Maintenance-free with long-term stable operation - Harsh environment compatibility: Operates in -40°C to 85°C, 0 to 100% RH, and 80 to 110 kPa - Easy integration: Dual relay output, RS-485 interface, and mounting bracket included - Self-diagnostic function: Detects faults and lifespan, notifying via relay and LED - Multi-refrigerant compatibility: Detects R-32 and R-454B with a single calibration - Compliance with safety standards: UL 60335-2-40, UL 60335-2-89, RoHS compliant ■ Target Users HVAC design engineers considering the transition to A2L refrigerants For product specifications and case studies, please contact us or use the document download option.

We exhibited at the exhibition "Smart Sensing 2025," held at Tokyo Big Sight from June 18 to 20, 2025. A diverse range of technologies and products that expand future possibilities, from sensor technology to AI and data utilization services, were showcased, and many visitors came to our booth. This time, along with our environmental sensors, flow sensors, and automotive modules, we also displayed six types of demonstrations. SEN66: Indoor Air Quality Combo Sensor Module SGD43S: Refrigerant Detection Sensor SCD43 / STCC4: CO₂ Sensor SLF3S: Liquid Flow Sensor SAAF: Fogging Detection and Automatic Defrost Sensor Visitors had the valuable opportunity to see products that cater to a wide range of applications, including air quality measurement, gas leak detection, visualization of factory safety management, and flow measurement and control in the semiconductor, medical, and research fields, while experiencing the sensors' fast response and high precision. Thank you very much to everyone who visited our booth. We sincerely appreciate the many attendees who contributed to the lively atmosphere of the exhibition each day.
