PYD 1788, PYD 1798 Dual-Element DigiPyros
The NEWLY IMPROVED PYD 1798 is now re-engineered for improved energy efficiency of a mere 1.8V at 5µA power requirement, making it an ideal motion detection sensor for extended service life in mobile and remote battery-operated devices. Both of these Excelitas Dual-Element Pyrodetectors feature two elements in series connection in TO-5 Metal Housing with optical window options. This Pyrodetector Series is part of the DigiPyro®family that feature internal integrated circuitry to convert the element signals into a 14-bit digital output.
This DigiPyro®Detector Series in TO-5 housing includes Dual-Element types with different window sizes. The element configurations are identical, along with the internal electronic circuits.
The PYD 1788 has the standard size window for economy and mid-range sensing, while PYD 1798 has an enlarged window enabling broader fields-of-view. Both the PYD 1788 and PYD 1798 models include a built-in temperature diode which provides output related to the Pyro internal temperature. This makes the output signal into a 14 +14 bit signal, communicated in one digital bit stream of 2x14-bit output via a single wire “Direct Link” connection to a suitable host microprocessor.
