Through-beam Sensor with Infrared Emission - 20m
A detection system with separate emit-
ter and receiver units, allows the user
to reach larger operating distances. The
sensitivity adjustment, present on the
receiver, allows adjustments enabling
the sensor to detect objects that block,
even partially, the light emission. The IR
emission is modulated to avoid interfer-
ence with other light sources and can
be turned off to test the sensor even
without an object to detect.

Technological Advantages
The S60 series establishes a new standard in compact 50 x 50mm photoelectric
sensors, offering a complete family of optical functions within a 15mm housing
width.
The standard dimensions, reduced housing width, and the multi-hole mounting
system make the S60 series superior to the majority of compact sensors present
on the market.
The models are available with M12 connectors, NPN or PNP output, and conform
to EN60947-5-2 European standards.
The M12 connector can be easily rotated to 90º and can be locked in straight
or right-angle positions compared to the optic axis. The cable emerges at 45°
and can be bent almost 360º. These characteristics allow the sensor to be easily
mounted on any side and at any angle.
The S60 series are available in through-beam, polarized retro-refl ective and
diffuse proximity. The polarized retro-refl ective model is available with a coaxial
optic version with the emitter optic axis coinciding with the receiver. This offers
superior detection axis precision and eliminates the blind zone near the sensor.

Coaxial optics are also available in the polarized retro-refl ective model for
detection of transparent objects. This increases the performance of the optical
function and its immunity to object movement inside the detection area.
The range and switching threshold output can be selected from 50 - 150mm,
with a ± 1mm precision; direct or inverse proportionality and light or dark operat-
ing modes can also be selected.

General Information

USA: 800-262-IDEC Canada: 888-317-IDEC
PLCs Operator Interfaces Automation Software Power Supplies Sensors Communication & Networking
Sensors
General Information
It is strongly recommended to avoid using any sensor where it will be continually subjected to elements which
impair performance or cause corrosive damage to the sensor. In particular, avoid strong vibrations and
shocks, corrosive gases, oils and chemicals, as well as blasts of water, steam, dust or other particles.
Specifi cations
Do not operate a sensor under any conditions exceeding these specifi cations.
Do not operate a sensor under current and voltage conditions other than those
for which the individual sensor is rated.
Do not exceed the recommended operating temperature and humidity. Although
sensors are rated for operation below 0°C, this specifi cation does not imply
that performance characteristics will remain constant under prolonged freezing
conditions. Continued exposure and the accompanying frost, ice, dew, and con-
densation which accumulate on the optical surface will adversely affect sensor
performance.
To maintain performance characteristics, do not exceed vibration and shock
resistance ratings while operating a sensor. In addition, avoid impacts to the
sensor housing which are severe enough to adversely affect the waterproof
characteristics.
IEC (International Electrotechnical Commission) Ratings
Sensors rated IP67 are resistant to moisture when occasionally immersed in
water. Sensors rated IP64 through IP66 are resistant to moisture when occasion-
ally subjected to splashing or when located in the vicinity of turbulent waters.
These ratings do not imply that a sensor is intended for use under continual
high-pressure water spray. Avoid such applications to maintain optimal sensor
performance.
Sensors rated IP64 through IP67 are dust-tight and water-tight. For best perfor-
mance, avoid using any sensor in an area where it will be subjected to heavy
particle blasts and where dust, water, or steam will accumulate on the optical
surface.
Start-up
Do not test the housing for dielectric strength and insulation resistance, since
the housing is connected to the electronic circuit ground of a sensor. Do not
perform dielectric strength and insulation resistance tests on electrical systems
without disconnecting photoelectric sensors, as such testing may result in dam-
age to the sensor.
Several lines of sensors, as noted in the individual operation sections, are pro-
vided with an internal circuit to turn an output off for a specifi ed amount of time
upon power-up. This delay is normal; it prevents a transient state when turning
power on.
Optimum Performance
The optical surface of each sensor must be cleaned on a regular basis for
continual superior performance. Use a soft cloth dipped in isopropyl alcohol to
remove dust and moisture build-up.
IMPORTANT: Do not use organic solvents (such as thinner, ammonia, caustic
soda, or benzene) to clean any part of a sensor.
All sensors experience signal inconsistencies under the infl uence of inductive
noise. Do not use sensors in close proximity to transformers, large inductive
motors or generators. Avoid using sensors in direct contact with sources of
excessive heat. Also avoid operation in close proximity to welding equipment.
Light
Visible light is electromagnetic radiation with a wavelength be-
tween 390 and 770nm. White light is composed of all the vis-
ible spectrum components in equal quantity; the predominance of
a specifi c wavelength determines the color of the light. Light Emit-
ting Diodes (LEDs) are the most common light used in optoelectronics.
Transmission, Absorption, Refl ection
When light hits an object three things
take place at the same time: refl ection
(ρ), absorption (α) and transmis-
sion (τ); with parameters and ratios
that vary according to the object
themselves, which are then further
differentiated by material, surface, thickness and/or color. These elements can
be detected using a photoelectric sensor.
Extraneous Light
Bright, extraneous light such as sunlight, incandescent lights, or fl uorescent
lights may impair the performance of sensors in detecting color or light.
Make sure that extraneous light does not exceed recommended levels found in
the individual specifi cations sections. When 500 lux is specifi ed, this is equal to
50 footcandles. The average factory illumination is ordinarily below this level,
except in areas where visual inspection is being performed. Only in such brightly
lit areas is incident light of particular concern.
Unwanted light interference can often be avoided simply by making sure that the
optical receiver is not aimed directly toward a strong light source. When mount-
ing direction cannot be adjusted, place a light barrier between all nearby light
sources and the receiver.
Through-beam Sensors
With through-beam sensors, the light emitter and receiver are
contained in two different housings that are mounted one in front of
the other. The light beam emitted by the emitter directly hits the
receiver; each object that interrupts the beam is detected. This system is used to
obtain large signal differences
(when the light directly hits the
receiver and when the object
interrupts the beam) with the
highest Excess Gain and the
largest operating distance reaching
up to 50m. These sensors can
operate in the harshest environ-
mental conditions, such as in the
presence of dirt or dust. The disadvantage is that two units have to be wired (an
emitter and receiver). The through-beam optic function operates typically in dark
mode: the output is activated when the object interrupts the beam between the
emitter and receiver.

Sensors
A slit attachment is available to modify the beam size of through-beam sensors.
This option is recommended for detecting very small objects (near the size of the
smallest object which a sensor can detect) or for eliminating light interference
when sensors are mounted in close proximity.
Retro-refl ective
Photoelectric sensors with this function contain both the emitter and
receiver inside the same
housing. The emitted
light beam is refl ected on the
receiver due to a prismatic
refl ector; an object is detected
when it interrupts the beam.
Compared to the through-beam
optic function, the signal
difference is reduced (when the
light is freely refl ected by the
refl ector and when an object
interrupts the beam) so Excess Gain is reduced and maximum operating
distances can reach 12 meters. It is necessary to operate in clean environments
without dirt or dust. A retro-refl ective sensor typically operates in the dark mode:
output is activated when an object interrupts the light beam between the sensor
and refl ector.
When installing sensors which detect refl ected light, make sure that unwanted
light refl ections from nearby surfaces, such as the fl oor, walls, refl ective machin-
ery or stainless steel, do not reach the optical receiver.
Also, make sure that refl ected-light sensors mounted in close proximity do not
cause interfering refl ections. When it is not possible to maintain the recommend-
ed clearance between sensors, as noted in the individual installation sections,
provide light barriers between sensors.
Prismatic Refl ector
A prismatic refl ector is able to refl ect incident light in a parallel manner, with a
refl ection coeffi cient higher than any other object for angles less than 15°. Typi-
cally the operating distance proportionally increases according to the refl ector’s
dimensions. The refl ector can rotate the incident light’s polarization plane at 90°.

Polarized Retro-refl ective
In presence of critical detection of objects with very refl ective surfaces,
such as shiny metals or mirrored glass, retrorefl ex sensors with polar-
ized fi lters have to be used. In polarized retrorefl ex sensors, the emis-
sion light is polarized on a vertical plane, while the reception is obtained only
through a polarized fi lter on a horizontal plane. A prismatic refl ector rotates the
light plane at a right angle, while the light refl ected from the object maintains
polarization plane unvaried and is blocked by the fi lter placed on the receiver.
Consequently, only the light refl ected by the prismatic refl ector is received.
Retro-refl ective for Transparent Objects
For detection of transparent objects, such as PET bottles or Mylar
sheets, a low-hysteresis retro-refl ective sensor (capable of detecting
small signal differences) can be used. These sensors detect small
signal differences that the light undergoes when it passes through a transparent
object.
Diffuse Proximity
Photoelectric sensors with this function contain both the emitter and
receiver inside the same housing. The emitted light beam is refl ected
on to the receiver directly by the object, which is detectedwithout the
need of prismatic refl ectors. Proximity
sensors represent the most economic
and fastest mounting solution.
However, they work with weaker
signals compared to retro-refl ective
sensors. Excess Gain is reduced and
operating distance, depending on the
object’s refl ection degree, can only
reach 2 meters.
A proximity sensor normally operates
in light mode: the output is activated when an object enters the detection area
and refl ects light emitted by the sensor.
Background Suppression
Background suppression sensors allow the operator to precisely set the
maximum detection distance. The operating distance adjustment is not
based upon the receiver’s
sensitivity, but is obtained through
optic triangulation, mechanically
acting on the lenses or photoelements
angle or electronically using PSD
(Position-Sensitive Detectors)
receiving systems. Consequently the
detection of an object is independent
of other objects behind (or in the
background), which are suppressed.
Moreover, due to this adjustment
method, all objects can be detected at
the same distance independent of
their color.
Distance Sensors
Distance sensors supply an analog signal of 0-10V or 4-20mA propor-
tional to the measurement of the distance between the emitting optics
and the target.
The main technologies involved are optic triangulation and time-of-fl ight. The
fi rst allows very precise measurements on short distances, while the second is
ideal for medium and long distances.

Slot Sensors
A slot sensor is a version of a through-beam retro-refl ective sensor,
where the emitter and receiver are
placed opposite each other on the
inside of an U-shaped housing. Any target that
passes through the internal slot interrupts the
beam and is detected. Due to their construction,
slot sensors are great for applications with short
operating distances. The most typical slot sensor
applications are hole or teeth detection on gears,
label detection, or edge control and continuity of
sheets or tapes. The emission is generally
infrared light; however visible red or green
emission versions are available and able to detect references such as registra-
tion marks, that present color contrasts on transparent fi lm.
Contrast Sensors
Contrast sensors (also defi ned as color mark readers) present a
proximity function but, instead of detecting only the presence or
absence of an object, they are able to distinguish between two
surfaces. This accomplished by
detecting the contrast produced by
the different refl ection degrees. In
this manner a dark reference mark
(low refl ection) can be detected
due to the contrast with a lighter
surface (high refl ection), or vice
versa. In the presence of colored
surfaces, the contrast is highlight-
ed using an LED, typically red or
green. For general purposes a white light is used because the full light spectrum
detects the majority of contrasts. White light emission is obtained through
lamps, or LEDs in most sensors, enabling the detection of very slight contrasts
due to different surface treatments, even of the same material and color.
Contrast sensors are mainly used in automatic packaging machines for registra-
tion mark detection to synchronize folding, cutting and welding.

Red no medium medium
Orange low medium medium
Yellow low low medium
Green high no medium
Blue high medium high
Violet medium high high
Brown low medium high
Black high high high
Gray medium medium medium
White no no yes
Luminescence Sensors
‘Luminescence’ is defi ned as visible light emission from fl uorescent or
phosphorous substances, due to electromagnetic radiation absorption.
Luminescence sensors emit ultraviolet light, which is refl ected at a
higher wavelength (minor energy) on a
fl uorescent surface, shifting into the
visible light spectrum. Ultraviolet light
emission is obtained using special
lamps, or LEDs in sensors. UV
emission is modulated and the visible
light reception is synchronized.
Maximum immunity against external
interferences, such as refl ections
caused by very shiny surfaces, is
obtained. In addition, fl uorescent targets, invisible to the human eye, can be
detected. Luminescence sensors are used in various industries: detecting labels
on glass or mirrors in pharmaceutical and cosmetic fi elds; selecting tiles marked
with fl uorescent marks in the ceramic industry; determining the presence of
fl uorescent glues on paper for automatic packaging; distinguishing cutting and
sewing guides in textile manufacturing; checking fl uorescent paints or lubricants
in mechanical production.
Color Sensors
The color of an object depends on all the color components of the
incident light which are being refl ected, eliminating those which have
been absorbed. The dominant color is defi ned as ‘hue’ and depends on
the refl ected light’s wave-
length. ‘Saturation’ indicates
the pureness of the color with
respect to white and is
represented as a percentage.
Hue and saturation together
are defi ned as ‘chromaticity’.
Color or chromatic sensors
have a proximity function with
generally three RGB LEDs for
light emission. The color of
an object is identifi ed according to the different refl ection coeffi cients obtained
with red (R), green (G) and blue (B) light emissions. More simply, yellow can be
identifi ed by R=50% G=50% B=0% refl ections; orange by R=75% G=25% B=0%
refl ections; pink by R=50% G=0% B=0% refl ections; but possible combinations
are really infi nite. Color sensors operate only on refl ection ratios and are not in-
fl uenced by light intensity, defi ned as ‘brilliance ‘or ‘luminance’. There is a wide
range of applications, ranging from quality and process controls, to automatic
material handling for identifi cation, orientation and selection of objects accord-
ing to color.
Fiber Optic Sensors
Universal functions of through-beam and proximity sensors, as well as
application functions ranging from contrast and luminescence to color
detection, can be obtained using fi ber optic sensors. The optical fi bers
can be thought of as cables that transport light and can be used to place the
sensor’s optics in small spaces, or to detect very small objects.
An optical fi ber is composed of cylindrical glass (or a plastic core), surrounded
by Tefl on or Silicon coating. The difference between the core and the coating
refraction indexes allows the light to be diffused inside the fi ber in a guided
manner. The coating is covered by a plastic or metal sheath, which has an exclu-
sively mechanical protection function. Fibers with a glass core and metal sheath
are suitable for very high temperature uses, or for particular mechanical require-
ments. Plastic fi bers, offering great adaptability, are the most diffused in all

Sensors
applications. Plastic optic fi bers have a standard 2.2mm external diameter and
generally have a cylindrical threaded metal head on the end used for mechanical
mounting. These fi bers are usually 1 and 2 meters in length as reductions in per-
formance become signifi cant with lengths over 5 meters. Plastic optic fi bers can
be shortened using a special fi ber-cutting tool, but, it can only be used a limited
number of times. Cutting the fi ber with a non-sharp or non-perpendicular blade
will reduce operating distance. High temperature, extra-fl exible or high effi ciency
plastic optic fi bers are also available.
Through-beam fi bers
Proximity fi bers
Laser Sensors
A LASER (Light Amplifi cation by Stimulated Emission of Radiation) is
an electronic device, such as a diode, that converts an energy source
into a very thin and concentrated light beam, suitable for detecting
very small objects or to reach very long operating distances. With reference to
the safety of laser radiation (according to the EN60825-1 European standard)
class 1 requires that the laser device is safe under
reasonable operating conditions and is not dangerous
for people in any situation; while class 2 states that
the eye cannot be protected just by looking away or
blinking, thus precautions must be adopted to avoid
staring into the beam.
IMPORTANT: Always consider safety when installing a laser sensor of any
kind. Make sure that the laser beam cannot inadvertently shine into the eyes of
people passing by or working in the vicinity. See safety information on page 232.
Mounting
Mounting brackets and hardware are included with sensors, where applicable.
Use the hardware for mounting, along with washers and spring washers or lock
nuts. Do not overtighten hardware. Overtightening causes damage to the hous-
ing and will adversely affect the waterproof characteristics of the sensor.
Best results can be obtained when the sensor is mounted so that the object
sensed is in the center of the beam, rather than when the object is located near
the edges of the sensing window. In addition, the most reliable sensing occurs
when the majority of the objects being sensed are well within the sensing range,
rather than at the extreme near and far limits.
Wiring
Avoid running high-voltages or power lines in the same conduit with sensor
signal lines. This prevents inaccurate results or damage from induced noise. Use
a separate conduit when the infl uence of power lines or electromagnetic equip-
ment may occur, particularly when the distance of the wiring is extended.
IMPORTANT: Connect the sensor cables and wires as noted in the individual
Wiring sections. Failure to connect as shown in wiring diagrams will result in
damage to the internal circuit.
When extending sensor cables and wires, make sure to use cables equal or
superior to that recommended in the individual specifi cations sections.
When wiring terminals, be sure to prevent contact between adjoining terminals.
When using ring or fork lug terminals, use the insulated sleeve style only. Each
sensor terminal can accept only one ring or fork lug terminal.
Power Supply
Noise resistance characteristics are improved when a sensor is grounded to the
0V power terminal. If the 0V power terminal is not at ground potential, use a
ceramic 0.01μF capacitor which can withstand 250V AC minimum.
When using a switching power supply, be sure to ground
the FG terminal to eliminate high-frequency noise. The
power supply should include an insulating transformer, not
an autotransformer.
The compact PS5R-A power supply is the perfect compan-
ion item for most IDEC sensors. This power supply is only
1.77” (45mm) wide, 3.15” (80mm) tall, and 2.76” (70mm)
deep. Call an IDEC representative for more details.
Part Number Output Ratings
PS5R-A12 12V DC, 0.62A
PS5R-A24 24V DC, 0.32A
Miscellaneous
Strong magnetic fi elds may detract from the accuracy of the sensing measure-
ments. Avoid mounting a sensor directly to machinery, since the housing is con-
nected to the electronic circuit ground of the sensor. If it is necessary to mount a
sensor on machinery, use the insulating plate and sleeve provided.

Glossary
Attenuation: Reduction of beam intensity as a result of environmental factors
such as dust, humidity, steam, etc.
Dark on: Output energized when light is not detected by the receiving element.
For through-beam sensors, light from the projector is not detected by the re-
ceiver when an object is present. For refl ected light sensors, light is not detected
when it is not refl ected from an object surface.
Diffuse-refl ected light sensors: Sensors that detect all scattered and re-
fl ected light. Light refl ected from nearby surfaces, as well as the intended object
surface, is detected. Diffuse-refl ected light sensors are often called “proximity
switches,” since they switch when any object is near. Also use to detect color
contrast when colors refl ect light intensity differently (green LED recommended
for this application).
EEPROM: Acronym which stands for electronically erasable, programmable,
read only memory.
Excess gain: Ratio of optical power available at a given projector-to-receiver
range divided by the minimum optical power required to trigger the receiver.
Extraneous light: Incident light received by a sensor, not related to the
presence or absence of an object being detected. Extraneous light is usually
unwanted background light such as sunlight and incandescent lamps in close
proximity.
ΔE: The measurement of color difference as a three-variable function, located on
an XYZ axis of light, hue, and chroma values.
Hysteresis: The lag in response shown by an object in reacting to changes in
the forces affecting it . Operating point and release point at different levels. For
solid state sensors, this is accomplished electrically. For mechanical switches, it
results from storing potential energy before the transition occurs.
Light on: Output energized when light is detected by the receiving element. For
through-beam sensors, light from the projector is detected by the receiver when
an object is not present. For refl ected light sensors, light is detected when it is
refl ected from an objects surface.
Linearity: The measure of the extent to which a certain response is directly
proportional to the applied excitation.
NPN/PNP: Types of open collector transistors. NPN is a sink transistor; output
on establishes negative potential difference. PNP is a source transistor; output
on establishes positive potential difference.
Polarizing: Filtering out all refl ected light except that which is projected in one
plane only. Polarized retro-refl ected light sensors detect the light from corner-
cube type refl ectors when an object is not present.
Refl ected-light sensors: Sensors with the projector and receiver in one hous-
ing. Light is projected by the light source, and refl ected light is received by the
optical surface. Includes diffuse-refl ected, retro-refl ected, limited-refl ected, and
spot-refl ected sensors.
Repeatability: Ability of a sensor to reproduce output readings consistently
when the same value is applied consecutively, in the same direction, for a speci-
fi ed number of cycles, or for a specifi ed time duration.
Resolution: Overall dimension of the smallest object which can be detected
(when sensing the presence of an object) or smallest increment of distance
which can be distinguished with reliable results (when sensing the position of
an object).
Response time: Time elapsed between input and output. Total response time is
the sum of object detection, amplifi er response, and output response times.
Retro-refl ective: This type of refl ected light sensor uses a special refl ector to
return projected light when an object is not present. Sensor detects the presence
of an object when the light is refl ected differently.
Through-beam sensors: Sensors with a separate projector and receiver. The
light source from the projector is detected by the receiver, except when an object
is present.
Transient: Undesirable surge of current (many times larger than normal current)
for a very short period, such as during the start-up of an inductive motor.
