Background suppression
IDEC SA1E background suppression sensors determine the presence of target
objects based on a predetermined sensing distance. This means objects
beyond the cut-off range won’t be detected, and ensures that target objects
can be accurately and reliably detected regardless of color or reflectivity.
The background suppression (BGS) type sensor
determines ON/OFF status depending on the distance
from the object, and detects only the object.
