Amphenol Advanced Sensors T6743-40K-E Automotive CO2 Sensor

Amphenol Advanced Sensors T6743-40K-E Internal CO2 Sensor for Automotive Applications is a nondispersive infrared (NDIR) CO2 sensor that implements a single-channel diffusion sampling method for automotive HVAC applications. Those gas-sensing applications include automatic fresh air control and safety sensing for CO2 refrigerants. Amphenol Advanced Sensors T6743-40K-E Automotive CO2 Sensor features a patented ABC Logic™ lifetime calibration warranty. The sensor also offers low power consumption, a compact design, and simple product integration.
