The MPY20-A112T pyroelectric gas sensor employs a high-performance lithium tantalate crystal as its sensitive element. This material offers a small relative dielectric constant and a high specific detection rate, enabling precise infrared absorption measurement for gases like CO2. Its pyroelectric coefficient remains remarkably stable across a broad temperature range, resulting in a minimal output signal drift of only 1-2‰ per degree Celsius.
Designed in a TO-39 package with a JFET integrated for impedance matching, the sensor operates in voltage mode. It features a fast thermal time constant of 150 ms and a high internal feedback resistance of 50 GΩ, making it highly responsive to changes in infrared radiation. This sensor is engineered for applications requiring reliable, long-term gas concentration monitoring without frequent recalibration.
