Excelitas PYQ 1348/PYQ 1398 Single-Output, Quad-Element Pyrodetector Series
PART/ PYQ 1398, PYQ 1348

PYQ 1398, PYQ 1348 Single-Output Quad Pyros

Excelitas' PYQ 1348 and PYQ 1398 Pyrodetectors provide four sensing elements in a geometric square placement. Electrically all elements are connected in series, forming one analog output signal. The two versions vary from each other by different window size and element spacings.

This "Quad" Pyrodetector Series provides all four elements connected to one common output. All elements are electrically connected to one FET in source follower connection forming one analog output signal.

Two different window options are provided: Rectangular window or square window size. Different geometrical placements are available on request. When being applied with suitable lens or mirror optics these detectors are used in ceiling mount devices. The PYQ 1348 is also available with smaller elements of 0.8x0.8 mm². Small elements are suitable for compact lenses and short detection distances.
