Features
Adaptable to all environments
The detection areas can be freely adjusted in the left, right and longitudinal directions. The unit makes reliable detection and activation possible right up to the door for various kind of applications.
Superior stability
AIR sensors and microcontrollers are generally immune to the effects of external factors such as rain, snow and insects.
Simple Adjustment
Two settings left and right (3.5°each) and 8 settings for depth (1°each) provide 720 different possible patterns for the activation detection area.
