Omron E3X-NH Manual

High-Precision Fiber-optic Amplifier
The E3X-NH Employs a 16-Bit
Processor as An Industry First
An Automatic Sensitivity Adjustment
H
feature allows stable detection of
objects in frequently changing
environments
Three teach modes for optimal sensing
H
8-point scaled sensitivity meter is ideal
H
for high precision sensing and
through-beam applications at long
distances (and clearly displays a
target's reflectivity level)
A manual fine tuning sensitivity feature
H
allows 13 threshold adjustments using
an easy-to-read digital scale
Ideal for detecting small objects or fine
