Smallest digital pyroelectric detector on the market enables miniaturized smart devices.

WALTHAM, Mass., September 8, 2021 – Excelitas Technologies® Corp., a leading industrial technology manufacturer focused on delivering innovative, market-driven photonic solutions, today introduced its Miniature DigiPyro® PYD 5731 pyroelectric detector, offering the smallest footprint of any pyroelectric detector currently on the market. The PYD 5731’s small size and superior performance make it ideal for applications where packing density, space constraints and product miniaturization require the smallest possible sensors, including integration with intrusion alarms and other smart home products using analog and/or digital detectors for indoor / outdoor uses.
The new PYD 5731 sensor has an integral temperature reference, and a state-of-the-art, low operation voltage of 1,8..3,6 V. It provides excellent shielding and communicates in one 2x14-bit digital output through its single-wire “Direct Link” interface with the hosting microprocessor. While standard pyroelectric detectors are typically mounted in a TO-5 metal package, the new PYD 5731 comes in a TO-46 package with only 5,5 mm diameter. The combination of digital output and metal shielded package provides an outstanding EMI immunity along with the known high radiation sensitivity of Excelitas’ Digipyro family.

“Our DigiPyro pyrodetectors are engineered to the smallest form factors available and provide high-performance motion detection, human presence monitoring and remote temperature measurement,” said Fred Plotz, Product Manager, IR Sensing at Excelitas. “DigiPyro’s advanced sensor intelligence, sensitivity and connectivity are enabling acceleration and growth in smart home and smart cities markets, fulfilling a variety of functions to improve machine-to-human interface in today's smart products. The newest, smallest DigiPyro detector allows even further miniaturization of sensor-dependent smart products in space-critical environments and applications.”

DigiPyro sensors enable smart home/smart city systems to monitor and adjust HVAC temperatures, power lights on and off, activate security cameras and burglar systems, and enhance the intelligence and autonomy of home appliances. They are also used in gas and smoke detection systems, helping keep families safe.
