ZX LASER SENSORS
for precise measurement
Unique Plug & Play Concept
Advanced Industrial Automation

The ZX laser sensor series from Omron, the world’s leadin
sensor manufacturer, sets new standards in precise
measurement sensin . Based on a unique Plu & Play concept, the ZX enables a variety of
interchan eable sensor heads to be connected to the same amplifier. This concept not only
covers all of your measurement requirements, it also takes the costly and time-consumin
‘trial-and-error’ process out of selectin the best sensor heads for the job!
Unique measurement
sensing concept from Omron
The ZX is the world’s smallest and lightest laser measurement
sensor, which really expands the design possibilities for production
systems. Its body size is similar to that of a photoelectric sensor,
making it a ery attracti e solution where space around the location
and installation is at a premium. The ZX also features a host of
remarkable features and functions, including auto calibration, Auto
Thickness Calculation, flexible mounting direction, and flexible
quality control, which enables it to detect and log data for more
efficient and effecti e quality control.
Read on, and see why Omron’s ZX is ideal for all your
measurement sensing needs.

Very precise
The ZX sensor offers the same kind of hi h-speed response
as that of photoelectric sensors. With a resolution of 0.2
micrometres it is also very precise, and can immediately
spot errors or discrepancies that could cost time and money
in production processes. There are four detectin distances
for reflection types, ran in between 30 ± 2 mm, 40 ± 10 mm,
100 ± 40 mm and 300 ± 200 mm.
With the throu h-beam type the ZX sensor offers three
different measurement widths from 1-to 2.5 mm, 5 mm,
and 10 mm with a resolution of 4 micrometres.
In differential calculation mode the ZX sensor can catch
minute chan es in si nals, and the threshold level can be
set to catch upward or downward si nal chan es.
What’s really innovative about the ZX sensors is that the same amplifier unit
can be attached to any one of the six diffuse reflection laser displacement
heads, two mirror reflection-type laser displacement heads or three
throu h-beam types laser displacement heads in the ran e. You simply
select the sensor head that best suits your measurement application.
ZX LASER SENSORS
Designed to suit your every measurement need

The ultra small Laser-Spot can detect minute items like
IC-pins. For rou h surfaces like wood or paper the Laser-Beam
type will detect stable and without any influence by the
surfaces. Ideal function settin s are possible by usin both
the displacement mode and the li ht-intensity mode to meet
multiple application needs.
Instant results
Simply by connectin the amplifier unit to the sensor head
and applyin power, the distance value and threshold level
between the sensor head and object is displayed
instantaneously. The built in dual-di ital display provides the
real distance and can be chan ed to volta e/ current display
or display for intensity of reflective li ht.
Calculation unit for thickness-measurement
By insertin a ‘calculation unit’ between two amplifiers the
thickness-measurement is easily obtained, and the thickness
of measured products will be displayed on the sensor head.
This technolo y (patent pendin ) eliminates the need for
connectin a di ital panel meter and the troublesome wirin
and settin up associated with it.
Advanced easy-to-use functions
Advanced easy-to-use functions provided by the ZX sensor
include Scalin , Reverse Display, Display-OFF Mode, ECO
Mode, Display Di it Chan e, Measurement (Timer/Hold
Functions), Threshold Settin , I/O Settin , Mutual Interference,
Function Lock, Initial Reset, Zero Reset, Derivative Function,
Sensitivity Selection and Monitor Focus.
Flexible mounting direction
Thanks to the compact size of the sensor head Omron has
been able to develop a side-view attachment (sold separately)
that enables a variety of mountin possibilities.
This attachment can be used with any of the sensor heads
in the ZX sensor ran e.
Meeting multiple application needs
Line beam Spot beam

The ZX sensor’s auto calibration features means that it senses
itself before it starts sensin ! This eliminates the need for
time-consumin calibration routines. In addition, the sensor
automatically reco nises whether a reflective or throu h-beam
sensor head is connected, and chan es to the optimum
function settin for fast, accurate operation.
Easy-to-see resolution (patent pending)
With the resolution display function, a differin resolution
based on the object (repeatable hi h level of accuracy) can
be easily verified in real time. This function can verify the
resolution by a beam hittin and measurin the object.
By displayin the resolution, it is possible to control the level
of flexibility over the threshold set-up, and detection results
can be quickly confirmed.
Teaching functions for fast and easy set-up
The ZX sensor features three teachin functions that rival the
performance of current photoelectric sensors. These include:
Position teaching
For hi h-precision positionin
applications.
2-point teaching
For detectin ultra-small level differences
between two points.
Automatic teaching
For teachin under production conditions
without stoppin the work-piece.
The ZX sensor is easy to set up and practically maintains itself.
Here’s why:
Self-diagnostics
The ZX sensor features a built-in laser lifetime monitor so that
as soon as laser diode deterioration is detected, a warnin
appears on the sub-di ital display. This early detection system
enables timely, trouble-free replacement.
Easy-to-read display
Settin up and maintainin the ZX sensor is an easy process,
thanks to the easy-to-read display on the sensor head.
This display clearly shows detected measurement results,
which can be anythin from the distance value, threshold level
and the difference value between the sensor head and object
to Auto Thickness calculation. The dual-di it display can be
chan ed from ‘distance’ display to ‘volta e/current’ display or
a display for intensity of reflective li ht. In addition, the
resolution based on the real object to be measured can
be displayed.

Setting up and monitoring
via C
The ZX sensor can be equipped with the Smart Monitor
option, a software sensor set-up tool whose standard RS-232
connection enables it to be used with a Notebook or PC.
This software packa e is ideal for quickly and easily settin up
parameters and values via the menu screen from a floppy or
hard disk. Data lo in results can be processed usin this
software for quality control information, leadin to smoother
production runs.
Additional easy waveform monitorin (such as an oscilloscope)
can be used to analyse the si nal, and by usin the dra & drop
tool the threshold settin is easily obtained.
