The E3Z-LS is said to be the only diffuse photoelectric sensor offering both foreground and background suppression. Background suppression function works in applications where the background can cause false detections.
Foreground suppression is used with targets having shiny or irregular surfaces. The sensor’s low black/white error of 10% ensures reliable detection regardless of the target’s color or glossiness. Visible beam allows easy alignment while the sensor’s algorithm minimizes the effect of external light interference from fluorescent lighting.
