PA18 and PH18 Series - Photoelectric Sensors
PA/PH18 Series
Compact Photoelectric Sensors
This powerful PA/PH18 sensor series, with its cost effective,
compact design and robust ABS housing, offers a space
saving and easy-to-clean solution for a variety of applications in e.g. material handling, textile and food & beverage
industries. Due to their longer sensing distance, their highspeed detection and their improved LED diagnostics, the PA/
PH18 sensors provide an excellent price to performance ratio.
Being resistant to high temperatures, high-pressure cleaning,
strong cleaning agents and disinfectants, these sensors are
especially well suited for reliable detection in harsh environments.
The PA/PH18 series is available in a variety of versions:
The PA18 comes in an axial or a radial version and the PH18
in a square version. Both PA18 and PH18 are available as
diffuse reflective with narrow or wide viewing angle, diffuse
reflective with background suppresion, retro-reflective, polarized retro-reflective and through-beam sensors.
High Technology
A built-in microprocessor guarantees advanced filtering and
detection ensuring flexible customized solutions.
Easy Adjustment
A very precise and linear sensitivity adjustment and use of
a manual potentiometer provide accurate and easy setting
from close distances to full range.
Easy Mounting
The PA/PH18 series comes with a new mounting accessory
that facilitates fast and easy mounting.
Easy to Clean
Due to the smart and simple mounting accessory and the
robust design of the sensors, cleaning has become more effi
cient and easier.
High Immunity
The PA/PH18 sensors possess a remarkably high immunity to
light and electromagnetic disturbances. System maintenance
is hereby reduced and the application uptime is increased.
Harsh Environments
The PA/PH18 sensors have been developed to operate in
the harshest conditions. They conform to the standards of
ECOLAB, IP67 and IP69K.

The potentiometer can be left on maximum for plug & play setup, or the sensitivity level can be optimized as circumstances may require. For retro-reflective
and through-beam versions this allows
detection of semitransparent objects.
Mounting
Installation of the PA/PH18 sensor is
swiftly and easily carried out by means
of a new mounting bracket, APA/
APH18-MB1.
In addition, this simple accessory
results in a smooth and neat finish and
a space saving, easy-to-clean appli
cation.
Laser engraving has replaced the sensor label ensuring that the information
stays intact after any cleaning process.
The sensor functions are easily diagnosed by the dual LED indication in
three combinations.
IP69K and ECOLAB
Built to withstand cleaning with water
at 80°C (176°F), high pressure washing up to 100 bar (1,450 psi) and
to resist alkaline and acidic cleaning
agents, the PA/PH18 sensor series is
an excellent solution for applications
where harsh cleaning methods are
required.

Technologically Advanced
The PA/PH18 photoelectric sensor is technologically advanced yet small,
economical and easy to use without compromising quality and durability
NO and NC in One
Sensor
The PA/PH18 sensors offer the freedom to choose between a normally
open and normally closed output. This
drastically reduces demands on
storage capacity
and stock
control.
Efficient Lens Design
The optimized aspherical lens
design re
sults in a wide
sensing angle and a
much longer sen
sing range.
Advanced
Microprocessor
The built-in microprocessor
uses advanced filtering and
detection principles which
efficiently eliminate false
detection caused by common light sources, flash
beacon lamps or electromagnetic interference.
Furthermore, this microprocessor achieves signifi
cant
ly faster
detection.
New background suppression principle
The new PA/PH18 background suppression sensor (BGS) is based on
a brand-new sensing principle. This
considerably increases the sensing
distance (200 mm for white and grey
objects, 150 mm for black objects) and
improves the detection accuracy of different colours, suppressing the background even more efficiently.
This revolutionary sensing technology
uses an Active Pixel Sensor (APS) CMOS
array of 64 x 1 sensors, where each
pixel represents a specific position. It takes
advantage of the fact that the reflected
light hits the APS array at exactly the same
position. This way, the object’s mass
centre can be found regardless of the
energy of the received light. Using
this technology, grey, black and white
objects are detected at almost exactly
the same distance.
Furthermore, unlike traditional CCD
arrays, the CMOS array benefits from
being immune to the blooming effect
- not letting the light bleed onto other
pixels and disturbing the detection.
