PART/ PYD 1794
PYD 1794 Dual-Element low profile DigiPyro
The PYD 1794 Dual-Element Digipyro Detector features two elements in series connection in the low-profile TO-39 Metal Housing with optical window. This Detector is part of the Excelitas DigiPyro family that feature internal integrated circuitry to convert the element signals into a 14-bit digital output.
The PYD 1794 DigiPyro is the low-profile version of the DigiPyro family. An internal integrated circuitry converts the sensing element signals into a 14 bit digital output. In addition, an internal diode provides output related to the Pyro internal temperature. This makes the output signal into a 14 +14 bit signal. For details see our links for application notes and the specification below.
