The new TO-39 pyroelectric IR detector range has a four times improved signal-to-noise (SNR) ratio thanks to the characteristics’ optimization of a patented thin-film PZT for methane and hydrocarbon-specific wavelengths. It also features increased responsivity of 270,000 Volts/Watt within the filter band. Sensor elements are built into a low noise circuit that has an internal CMOS op amp, with a 10 GΩ feedback resistor outputting a voltage signal centred around half the supply rail. The methane (CH4) variant in TO-39 analog format is sampling now, and orders are being taken for digital SMD samples in a dual package.
