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