Opto Diode Corporation, an ITW company, presents the BXT2-17TF, a single-channel, infrared (IR) detector with an integrated 4.67 µm optical bandpass silicon filter. The high-performance lead selenide (PbSe) cooled device provides excellent sensitivity for industrial carbon monoxide (CO) detection in harsh environments.

The two-stage, thermoelectrically-cooled, packaged device with integrated thermistor joins Opto Diode’s B-Series IR detectors, all of which feature excellent performance and high reliability for long life. The BXT2-17TF provides additional sensitivity for low-level-emissions detection and enhanced temperature stability for use in harsh environments where temperatures are in constant flux.

The device has minimum responsivity of 1.2 x 105 V/W with the active-element temperature controlled to -30 °C. Housed in a standard TO37 can, the unit has a 2 mm² active area. Absolute ratings for storage and operating temperatures range from -40 °C to +85 °C.  Additional uses include carbon monoxide gas analysis, environmental monitoring, process control systems, and industrial burner monitoring and control.
