Surface-Mount PIR Sensor Saves Space

Thanks to the company’s technology and new pyroelectric ceramic materials, Murata was able to craft a smaller lead-free, surface-mount pyroelectric infrared (PIR) sensor. Available from TTI, the sensor is designed to withstand solder reflow processes and is capable of better detection accuracy than traditional PIR sensors, claims Murata.

By making the sensor surface-mountable, the device now occupies 30% less in volume versus that required by traditional PIR sensors. Height was also reduced to approximately 60% that of its traditional counterparts, enabling the sensor to be used in “thin-model” or “low-height” electronic devices and equipment.
