F661 Board-Mount Digital Airflow Sensor (Horizontal Profile)


The F661 is the smallest form factor, digital airflow sensor available on the market today with a horizontal flow profile. Designed to measure spatial airflow inside electronic or ducted systems, the F661 uses high performance dual element sensing technology and can be soldered directly to a printed circuit board, or plugged into a surface-mount socket for easy removal or maintenance. 

  • Smallest footprint air velocity sensor available
  • UART or I2C communication
  • Dual sensing element with protective shroud
  • Fully linearized air velocity and air temperature with wide operating range
  • Less than 20mA power consumption
  • Up to 5% Accuracy and Repeatability Rating
  • Addressing for up to 32 sensors on an I2C bus
  • Alarm output option available for switch style operation
  • Available flow learning command for product optimization, post-soldering
  • RoHS-compliant

Availability:  Shipment within 7-14 business. Volume orders may require additional lead time.
