Distance-settable Photoelectric Sensor
Switching between background and foreground
suppression (BGS/FGS) enables detecting a vari-
ety of objects under various background/fore-
ground conditions.
Influence of external interference, including
inverter fluorescent lighting, minimized with
unique avoidance algorithm.
Red beam for easy spot position confirmation.
Almost no differences in detection distances for
different colors.
Minimal hysteresis to enable detecting small steps
(2/3rds of previous models: E3Z-LS20@4S).
Same compact size as the E3Z Series: Use the
same Mounting Brackets.
