Overview
Murata Manufacturing Co., Ltd. has developed the world's smallest and thinnest surface mount
pyroelectric infrared sensor, "IRS-B series."
Our new model is even smaller than the previous reflow surface mount pyroelectric infrared sensor
available exclusively from Murata. This model will contribute to promoting mass production and price
reduction of reflow surface mount type sensors. It will also accelerate introduction of the human presence
sensor for consumer equipment in addition to allowing equipment size reduction.
Furthermore, we have developed a condenser "flat lens" used in combination with the pyroelectric infrared
sensor, contributing to thinner equipment manufacturing.
Background
Requirements for human presence sensing are increasing in various applications such as energy
conservation, theft prevention, appliances and care-giving. Previously, pyroelectric infrared sensors used in
human presence sensors tended to be large, and unsuitable for automatic surface mounting due to lead
mount construction, making them less cost effective and difficult to mass-produce.
To this end, Murata previously offered the only lineup of reflow surface mount pyroelectric infrared
sensors in the industry. We were able to further reduce the size of this newly developed "IRS-B series"
model, creating a smaller and thinner version, by improving Murata's own package technology and
pyroelectric ceramic materials. This model makes it possible to mount the human presence sensor on
equipment allowing the equipment to be smaller, thinner and lighter, such as appliances, low profile digital
equipment, PCs and video game consoles.
IRS-B series is approximately 50% smaller in volume and 10% thinner than our previous surface mount
model. Compared with common lead-type models, it is significantly smaller with a lower profile
approximately 20% less in volume and 50% less in thickness than the former.
Curvature of the "flat lens," developed together with "IRS-B series," was made extremely flat making it
possible to streamline the equipment design.
