Surface Mount Pyroelectric IR Sensor

Smallest and Thinnest in the World!

Smyrna GA , USA– ??Murata Manufacturing Co., Ltd. has developed the world’s smallest and thinnest surface mount pyroelectric infrared sensor, “IRS-B series.

Their 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, they 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.

They 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.

Features

  1. No. We do not as a rule sell any products directly. We do list some eBay offering and items that third parties sell but advertize them on our pages.

  2. Hi,

    Do you have any SMT’s with the above specs but the heat
    range alittle higer (95C, 200 degrees F.)

    Thanks so much

    Jose
