STG-EA11-F4.26

STG-EA11-F4.26 Product Introduction

The STG-EA11-F4.26 is an infrared thermopile gas sensor developed by Senba Sensing. The STG-EA11-F4.26 measures gas concentration (such as CO₂) by detecting changes in the resistance of its internal thermistor and uses a 4.26 µm narrow-band infrared filter for selective gas detection. The STG-EA11-F4.26 is housed in a TO-39 metal package and offers high sensitivity, thermistor temperature compensation, and fast response performance. The STG-EA11-F4.26 is used in indoor air quality monitoring, HVAC and ventilation systems, in-vehicle air purification, and industrial gas measurement applications.
