High sensitivityDescription
TX4041-A infrared gas sensor is a general-purpose, low-power infrared gas sensor (hereinafter referred to as the sensor). It utilizes the non-dispersive infrared (NDIR) principle to detect hydrocarbon combustible gases in the air, exhibiting excellent selectivity, ultra-low power consumption, no oxygen dependence, stable performance, and long lifespan; it also features built-in temperature compensation. This sensor is a compact, high-performance sensor designed by tightly integrating mature infrared absorption gas detection technology with micro-machining and sophisticated circuit design. It is easy to use and can directly replace catalytic combustion elements, making it widely applicable in various situations involving flammable and explosive gases.
