F661/F663

Board-Mount Digital Airflow Sensor (Horizontal Profile)

The F661/F663 is the smallest, fully-integrated, board-solderable, digital air velocity and air temperature sensor on the market, for real-time on-board measurement. The F661 (15-24V input) and F663 (5-12V input) can be soldered directly to a printed circuit board, or plugged into a surface-mount socket for easy removal. The lower profile is used in 1RU electronic systems, or those where component height is heavily restricted.

Dual sensing element with protective shroud

Provides fully linearized air velocity and air
temperature with wide operating range

Smallest footprint sensor on the market

Less than 20mA power consumption

Up to 5% Accuracy & Repeatability
Available flow learning command for accuracy
optimization, post-soldering
Digital UART or I²C Communication
Alarm output option available for switch style operation
