FLIR A65 A35 (Ax5-Series Features)

Extremely Affordable and Compact

FLIR’s Ax5-Series models (FLIR A65 A35) are low-cost thermal imaging temperature sensors that are ideal tools for monitoring temperatures in automation or machine vision environments.

High Thermal Sensitivity and Image Quality

The FLIR Ax5-Series produces high quality thermal images that can show temperature differences as small as 50 mK. Record crisp, 640 x 512 pixel thermal images with the FLIR A65, or for less precise applications, the A35 generates 320 x 256 pixel thermal images that still allow you to easily track temperature changes.

GigE Vision™ Standard Compatibility

GigE Vision is a camera interface standard developed using the Gigabit Ethernet communication interface. GigE Vision is the first standard to allow for fast image transfer using low-cost standard cables, even over long distances. With GigE Vision, hardware and software from different vendors can operate seamlessly over Gigabit Ethernet connections.

GenICam™ Protocol Support

The goal of GenICam is to provide a generic programming interface for all types of cameras. Regardless of interface technology (Gigabit Ethernet, Camera Link, IEEE-1394, etc) or features implemented, the Application Programming Interface (API) will always be the same. The GenICam protocol also makes it possible to use third party software with the camera.

14-bit Temperature Linear Output

Allows for non-contact temperature measurement within any third party software. A built-in Gigabit Ethernet connection allows real time 14-bit image streaming to computer.


Possible to configure one camera to be master and others to be slave(s) for applications that call for more than one camera to cover the object or for stereoscopic applications.
