The high-intensity 4-element red LED has
greatly improved the detecting distance.
The bright beam spot makes it easy to
align the optical axis.

A 4-element LED is used in upper-level fiber sensors
because its wavelength can be easily observed by the
human eye and the intensity change over time is small.

EA SY ADJU STMENT

Alignment indicator takes the guesswork
out of long distance sensor setup

Has your receiver
been bumped out of
alignment? How can
you tell?
Thrubeam PZ-G
models feature a bright
red LED indicator that
alerts you the instant
proper alignment has
been obtained. This
simple yet crucial
feature allows you to
troubleshoot setup and
run-time issues
quickly, before they
can snowball into
major problems.

Laser Marked tags eliminate
possible contamination

All information (model#, lot#, etc.) is laser
marked directly onto the sensor housing.
There are no labels, inks or paints to peel
or chip off into your products.

19 types of mounting brackets provide
a variety of mounting methods

A bracket can be selected according to the installation
conditions. 19 types, including a one-touch bracket, are
available.

Our oil-resistant cable ensures reliable
operation in an oily environment

In addition to the standard PVC cable, an oil-resistant PUR
cable is available for use in harsh environments.

PUR cable

Bipolar output (NPN+PNP) compatible
with any input device

Threaded models feature bipolar output (NPN and PNP),
eliminating the need to stock sensors for both outputs.

The mounting brackets shown above are only part of the lineup.
See page 7 for further details.

The interference suppression function
prevents interference from nearby units

With thrubeam models, up to two sensors can be mounted
in close proximity. Four sensors can be used by alternating
the transmitter/ receiver position.

High-speed targets can be detected
at a response speed of up to 500 s

A high-speed response of up to 500 s, twice as fast as our
conventional models, ensures detection on a high-speed line.
The high power ensures stable detection.

Different frequency beam

Differentiating the
number of sheets

The different frequency function automatically shifts the emission cycle if ambient
light is received by the receiver.

The P. R. O. function*
cancels direct
reflections from metallic

targets, allowing the
PZ-G to reliably detect
metal targets.

* Polarized Reflection Optics

DEX circuit

The PZ-G employs a DEX circuit*
(patented) that greatly amplifies the slight
light attenuation caused by transparent
targets ensuring stable detection.
