PYQ1398

The Excelitas Technologies PYQ1398 is a single-output quad pyrodetector designed for various sensing applications. It incorporates four pyroelectric sensing elements arranged in a geometric square configuration, with all elements electrically connected in series to provide a single analog output signal. This series offers different window sizes and element spacings to suit specific application requirements.

The PYQ1398 is housed in a TO-5 metal package, which provides effective EMI shielding. It features high-responsivity ceramic pyroelectric elements and an integrated FET in a source follower configuration for signal conditioning. An integrated EMI filtering stage further enhances signal integrity.

Key specifications include a typical responsivity of 6.2 kV/W and a field-of-view of 103°. The detector elements measure 1 x 1 mm². These pyrodetectors are suitable for applications such as mid-distance motion detection when used with appropriate optics, energy-saving devices, and intrusion alarms, particularly in ceiling-mounted configurations.

This detector series is designed for integration into systems requiring sensitive infrared detection. Its robust packaging and integrated features make it a reliable component for demanding environments.
