1388年PYD PYD1398 Dual-Element Pyros
This Pyrodetector Series represents Excelitas standard analog Pyrodetector offering. Our PYD 1388 (replacement to LHi 878) and PYD 1398 (replacement to LHi 968) Dual-Element Pyrodetectors feature two elements configured in a series connection with an FET in source-follower circuit. They are integrated into a robust TO-5 Metal Housing with an optical window
Both of these Pyrodetector models provide two sensing elements in opposed series connection with a source-follower circuit.
The PYD 1388 (pictured above on left) is the base model Pyro in this Standard Analog Series, while the PYD 1398 (pictured above on right) is equipped with additional features such as a larger window to reduce white light sensitivity and a gate resistor for better low temperature performance. Both sensors are available in 2 EMI versions. The standard version features 1 RC-Filter at drain and source pin. For applications in strong EMI conditions (5G and antennas close to the sensor) a version with an additional RC-filtering stage is available to further reduce interference effects of electromagnetic disturbances.
