PYD 5731 Miniature Dual-Element DigiPyro

With the diameter of 4.7mm the PYD 5731 Miniature, Dual-Element DigiPyro® is one of the smallest designs in the Excelitas Pyrodetector portfolio. The PYD 5731 features two elements in series connection in TO-46 Metal Housing with optical window. This Detector is part of the DigiPyro family that feature internal integrated circuitry to convert the element signals into a 14-bit digital output.

This Pyrodetector features a miniaturized Dual-Element Pyro in TO-46 housing with 4.7mm diameter and 3.3 case height. Furthermore, with the PYD 5731 Excelitas extends the emerging DigiPyro® family to miniaturized detector designs. The PYD 5731 offers the same Direct Link interface as the regular PYD 1798 DigPyro.

 

The miniature housing, in conjunction with a reduced element size and spacing, enables customers to reduce the size of their optics and innovate more compact product designs.
