Dual-Element Pyro Detectors

Excelitas Dual-Element Pyro Detectors are well established as the performance standard in motion detection. Our design features two sensing elements connected to each other in reverse polarity to provide an AC-signal with motion and common mode rejection for non-moving radiation. Specify various window sizes to meet desired fields-of-view. Our Dual-Element Pyro Detectors cover the advanced family of DigiPyros, including our Low-Power DigiPyros for battery-operated motion detection.
