Mouser Introduces the Industry's Most Sensitive & Lowest Power Active Infrared Proximity Sensors

Mansfield, Texas, USA — January 21, 2011 - Mouser Electronics, Inc., regarded as a top global engineering design resource for semiconductors and electronic components, today announced it is stocking new product from Silicon Labs.
    Silicon Labs Si114x QuickSense™ infrared proximity sensors are the industry's most sensitive and lowest power active infrared proximity sensors. Silicon Labs Si114x infrared proximity sensors feature an all-digital I²C control interface and up to three infrared LED drivers in an impressively small 2mm x 2mm clear QFN package. These Silicon Labs sensors are capable of controlling 1-, 2-, and 3-infrared LED systems, giving developers the freedom to implement one-dimensional systems with a range of up to 50cm or multi-dimensional systems capable of advanced motion sensing with a range of up to 15cm. Silicon Labs Si114x infrared proximity sensors extend battery life by reducing the Ir-LED on-time to only 25.6 µs. These QuickSense devices also feature an integrated ambient light photodiode that enables accurate light level monitoring in mixed-light source settings. To learn more, visit
