PYROMID LRM-292 is a dual-channel pyroelectric detector in a TO46 package with a 1.2 × 0.8 mm² lithium-tantalate element and 3.0 × 2.0 mm² aperture, featuring integrated CMOS OpAmp for single-supply operation. It operates from 2.7 to 5.0 V with a recommended voltage of +3 V and draws a maximum supply current of 900 µA. The detector has a 100 GΩ feedback resistor, 0.3 pF feedback capacitor, and thermal time constant of 75 ms, providing a voltage responsivity of at least 65,000 V/W and noise density of no more than 45 µV/√Hz at 10 Hz. Detectivity is typically 3.0 × 10⁸ cm√Hz/W. The field of view is 60° with standard filters. Operating and storage temperature range is -25 to +85 °C.
