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 fibre sensors 

because its wavelength can be visibly seen by the human 

eye and there is minimal change in intensity over time.

EASY ADJUSTMENT 

Alignment indicator takes the guesswork 

out of long distance sensor setup 

Has your receiver 

been knocked 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 escalate into 

major problems. 

Laser Marked tags eliminate 

possible contamination 

All information (model#, serial#, etc.) is 

laser marked directly onto the sensor 

housing. There are no labels, inks or paints 

to peel or chip off into your products. 

Easy-to-see blue trimmer

Our unique one-touch brackets can save you and your customers considerable time 

during installation or replacement.

Enhanced user-friendliness 

Standard M8 and M12 quick-disconnects 

make replacement easier 

The PZ-G features a standard pin-out, which allows it to be 

a drop-in replacement with existing wiring. 

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.

A bracket can be selected according to the installation 

conditions. 19 types, including a one-touch bracket, are 

available. 

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 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 µs 

A high-speed response of up to 500 µs, twice as fast as our 

conventional models, ensures detection on a high-speed line. 

The high power ensures stable detection. 

Adjacent sensor light 

Different frequency beam 

Differentiating the 

number of sheets 

The different frequency function automatically shifts the emission cycle if adjacent 

sensor light is received by the receiver.

[ Usage example 1 ] 

Suppressing interference between two thrubeam sensors 

Interference between thrubeam sensors 

can be suppressed with polarisation 

filters. A polarisation filter's characteristic 

depends on the direction and notch in 

which it is set. If the polarisation direction 

of the filters attached to the transmitter 

and the receiver is the same, the beam 

can be received. If the direction of the 

filter is changed by 90 degrees, however, 

the beam cannot be received. Using this 

restriction, interference can be 

suppressed with polarisation filters as 

shown.

[ Usage example 2 ]

With another set of sensors

interference between four

sensors can be suppressed 

by alternating the positions

of the transmitters and the

receivers. Be sure to pay 

attention to the direction of Receiver

* Remove the protective sheets on both sides of the polarisation filter before use. 

* Adjust the sensitivity if interference occurs even with polarisation filters.

Background Suppression Model Unaffected by Colour! 

Self-contained Photoelectric Sensors 

PZ-V Series 

Features 

Intelligent reflective type 

unaffected by a target's 

colour or angle 

Digital display 

High-power custom red LED 

(Except for PZ-V71) 

High-intensity operation 

indicator 

Here's How 

PSD (Position-Sensitive Detector) 

The target distance is detected according to the angle of 

the reflected light beam. 

• Unaffected by a highly reflective target background 

• Stable detection of targets with colours and materials of 

varying reflectance 

• Highly accurate detection of minute objects 

One-touch 

Fully-automatic calibration 

A.P.R. circuit (Automatic Power Reinforcement) 

Stable detection is possible due to the A.P.R. circuit 

which automatically adjusts the amount of light emitted 

according to the colour and angle of the target.
