PRODUKTINFORMATION

Subject to change without notice

Hitting the mark without the need for extensive preparation is the very denition

of precision. What makes fork sensors from SICK really stand out, however, is

more than just their accuracy – it’s also their outstanding equipment congura-

tion. The sender and receiver are integrated into a single housing, saving time

spent on alignment.

Sensors that operate using a through-beam design always require a certain amount of adjustment and

alignment. That is, unless the sender and receiver are both integrated into a rugged housing made of

plastic or aluminum – as is the case with SICK fork sensors. With their precise, focused beam of light, the

infrared, red light, laser, and ultrasonic variants that are available offer a key advantage when it comes to

reliable detection of labels, double sheets, and various types of objects. These sensors are even able to

detect very slight differences in light attenuation. A wide range of fork sizes, straightforward mounting, and

exceptionally high ambient light immunity are additional advantages that the fork sensors offer.

TEACH-IN PROCEDURES

TWO OPERATING CONCEPTS FOR INCREASED FLEXIBILITY

Various procedures are available for carrying out teach-in conguration of fork sensors. In addition to stat-

ic 2-point teach-in, a dynamic teach-in procedure is available for selection. This exibility is also reected

in the operating concept used when performing the teach-in procedure.

Operating concept with plus/minus buttons

• Static and dynamic teach-in procedure available

• Option of individual switching threshold readjustment using

plus/minus buttons

• Option of changing between light/dark switching

• Pushbutton lock can be activated and deactivated

Operating concept with teach-in button

• Standardized design

• Intuitive operating concept

• Static and dynamic teach-in procedure available

• Option of single-stage ne adjustment using teach-in button

• Option of changing between light/dark switching

• Pushbutton lock can be activated and deactivated

In addition to the proven variants that enable settings to be

made using plus/minus buttons, the teach-in button variants

provide the option of performing the teach-in procedure using

just one button. This means that SICK offers its customers

the advantage of an intuitive sensor that is equipped with one

and the same operating concept across all product variants.

Thanks to an IO-Link interface installed as standard and

optional smart automation functions, SICK fork sensors are

equipped for the long term, ready to face the requirements of

the future – and combine standard sensors with pioneering

sensor intelligence in order to do so.

PRINCIPLES OF OPERATION

TWO FUNCTIONAL PRINCIPLES ACHIEVE THE DESIRED RESULT

Switching output Q = dark switching

The switching output is active when the path of the beam

is interrupted; that is, an object is located in the path of

the beam.

Switching output Q = light switching

The switching output is active when there is no object in

the path of the beam.

Switching function

Active

Switching output Q Not active

Switching output Q

Active

Not active

In label recognition, this means:

The switching output is active when the label is present.

In label recognition, this means:

The switching output is active when the label is not

present.

Ultrasonic fork sensors

In this case, it is the material properties (such as thickness

and adhesion) that are evaluated and reliably detected, rather

than the transparency. Thicker materials absorb the sen-

sor’s ultrasonic properties more strongly than thin materials.

Transparent materials are detected regardless of their printed

design or color.

Fields of application

• Label detection

• Double sheet detection

• Adhesive surface detection

Optical fork sensors

Optical fork sensors detect objects via the interruption of the

light beam. Even slight differences in light attenuation are

detected reliably in this way.

Fields of application

• Label detection

• Counting and positioning objects

• Process control

There are two different principles of operation used in SICK fork sensors.

LABEL OR DOUBLE SHEET DETECTION

• Ultrasonic transmission source

• Detection of transparent, opaque, or printed labels

• Simple and precise setting of the switching threshold via

teach-in button or plus/minus buttons

• Not affected by metalized colors

• Response time of 250 μs

UFN – The clear choice for detecting transparent labels

Transparent, shiny, and metallic labels; white, opaque, and colored substrate; thin foils, foil on foil, paper on paper – modern

labeling machines are faced with a variety of materials and surface properties. SICK fork sensors always offer the right solution.

Optical fork sensors are able to detect opaque labels, for example, reliably. Ultrasonic fork sensors detect even transparent mate-

rials reliably, regardless of their printing design.

TYPICAL APPLICATIONS

• Infrared transmission source

• Optimized housing thanks to slim fork shape

• Simple and precise setting of the switching threshold via

IO-Link, teach-in button, or plus/minus buttons

• Smart sensor with integrated IO-Link interface

OBJECT DETECTION

In order to control various processes logistically, it is necessary to reliably detect certain objects on the conveyor belts. As soon

as an object passes the fork sensor, it is detected. Thanks to a whole host of different transmission sources and sizes, the right

fork sensor can always be found to suit every requirement. The design accommodates the sender and receiver in a single hous-

ing. Commissioning is as easy as the mounting process is quick, since no complex, time-consuming alignment is needed.

TYPICAL APPLICATIONS

• Infrared transmission source

• Simple and precise setting of the switching threshold via

IO-Link, teach-in button, or plus/minus buttons

• Fast response time (max. 100 µs)

SICK sensors with IO-Link functions that can be integrated into an automation system offer a whole host

of useful functions, from conguration and operation all the way through to monitoring.

Condition monitoring/diagnostics

Implementing diagnostic and self-test options enables

features such as contamination evaluation for sensors.

Thanks to the monitoring capabilities of the sensors, pre-

ventive maintenance can be carried out using a precise

maintenance plan. This ability to predict machine status

even extends across area boundaries. The advantages of

this are reduced maintenance and repair times, minimum

risk of failure, as well as accurate fault localization and

diagnostics.

The automation system provides the IO-Link sensor with

optimum application-specic parameters for the manu-

facturing process or the product being manufactured,

such as the sensing distance, hysteresis, or threshold.

The advantages of this are reduced machine downtimes

and changeover times when switching products, more ma-

chine exibility, and the prevention of incorrect settings.

Flexible sensor adjustment

Easy device replacement

Sensors with IO-Link can be replaced quickly and easily

as they are able to adopt the set function parameters

without any alterations. The parameters are stored in the

IO-Link master or in the control system. The advantages

of this are minimal downtimes, guaranteed machine avail-

ability, as well as recorded and documented replacement

processes.

IO-Link enables electronic documentation to be created

for all sensors in the as-delivered state of the machine

or plant, both quickly and automatically. The advantages

of this are increased transparency in the electronic

documentation for installed sensors, cables, and male

connectors. This prevents time-consuming troubleshoot-

ing resulting from different documentation versions.

Additionally, the machine or plant’s as-delivered state can

be documented easily and accurately in this way.

E-parts list/E-inventory

Sensor data such as the device ID, serial number, teach-in

values, hysteresis, and switching behavior can be displayed

and modied using visualization software via the SiLink Box

on the PC. All parameters can be optimized and transferred to

multiple sensors.

The advantages of this are:

• Comprehensive diagnostics options

• Availability values can be checked and parameters can be

optimized

• Simplied selection of function range and performance

capability

• Quick and safe sensor pre-conguration

• Easy identication of optimized application parameters

• Simple commissioning

SMART SENSOR SOLUTIONS – STANDARD FUNCTIONS WITH IO-LINK

OPTIMIZED AUTOMATION FOR MACHINES AND PLANTS

REGISTRATION SENSORS | SICK8014860/2016-07-04

Subject to change without notice

Remote debouncing

For some plants and machines, main-

taining productivity levels requires

sensors to know which detection signals

are disturbances, and to suppress those

disturbances using additional detection

information. This prevents the control

system from being burdened with infor-

mation that will disrupt the process. The

-A70 and -A71 fork sensor variants are

equipped with this function.

You will nd detailed information on Smart Sensor Solutions powered by IO-Link in

the special information with the same name (part number 8011727).

SMART SENSOR SOLUTIONS – ADVANCED FUNCTIONS WITH IO-LINK

By using state-of-the-art sensor technology and integrating it into an automation network, it is possible to

take advantage of innovative functions that have a direct impact on a plant or machine’s productivity.

High-speed counters

Some plants and machines have to

know how fast conveying equipment

is moving in order to carry out control

tasks, or they need to ensure that the

speed of a roller stays within dened

limits. Using the counting function in the

-A71 fork sensor variants, it is possible

to implement these and other automa-

tion tasks with maximum efciency.

Time measurement

In some plants and machines, it is

necessary to check that an object being

transported to another destination is the

right shape or in the right position on

the conveying equipment. The -A70 fork

sensor variant measures the time win-

dow directly and with high precision, and

provides the measurement result in the

format required by the control system

so that this information can undergo

further processing.

Product description

The UF ultrasonic sensors reliably

detects labels and materials, regard-

less of printed design, transparency or

surface characteristics. Unlike optical

sensors, the UF3 relies on damping – a

process where the thickness of a mate-

rial determines the degree to which the

sensor absorbs sound waves. A high

level of positioning accuracy and stable

response times make the fork sensor

suitable for nearly any environment. Due

to its small, compact metal housing,

the UF can be used in harsh conditions

and where space is limited. As a result,

the UF3 can distinguish between labels

located just 2 mm apart from one an-

other on an adhesive tape. Applications

include detecting transparent labels on

transparent substrates, detecting labels

with different printed designs or dif-

ferentiating between single- and two-ply

materials.

At a glance

• Detection of transparent, opaque or

printed labels

• Unaffected by metallic foils and

labels

• Fast response time of 250 µs

• Simple and accurate adjustment

via teach-in button, or plus/minus

buttons

• Rugged, IP 65 aluminum housing

Your benets

• Great exibility: UF identies labels

reliably - regardless of whether they

are transparent, opaque or printed

• Fast response times enable precise

detection – even at high web speeds

• Teach-in function enables quick and

easy commissioning

• The aluminum housing meets all re-

quirements for use in harsh industrial

conditions

• High process reliability: Ultrasonic

technology prevents false detection,

which may be caused by ambient

light or shiny surfaces

Setting the switching threshold

Teach-in dynamic via plus/minus buttons

Press “–” button, teach-in

process is finished.

2. Move multiple labels

through the fork sensor

Notes

Teach-in (static): Setting the switching threshold without movements of label, cf. operating instruction.

Press both the “+” and “–”

buttons together, hold > 1 s and

than release the teach-in buttons.

The red LED flashes.

1. Position label or substrate

in the active area of the

fork sensor

Once teach-in process is complete, the switching threshold can be adjusted at any time using

the “+” or “–” button. To make minor adjustments, press the “+” or “–” button once.

To configure settings quickly, keep the “+” or “–” button pressed for longer.

Switching threshold adaptation:

Only, the first teach-in procedure after switching on is permanently stored. Teach-in can be repeated

cyclically. Switching output also during teach-in active.

Press both the “+” and “–” buttons together (3 seconds) to lock the device and prevent

unintentional actuation.

Press both the “+” and “–” buttons together (6 seconds) to define the switching function

(light/dark switching). Standard setting: Q = light switching.

Teach-in dynamic via Teach-in button

Note

Light/dark switching

Fine adjustment

In order to obtain a higher operating reserve, a fine adjustment can be carried out after successful teach-in.

For this purpose, the switching threshold is set close to the taught-in object. The teach-in button must

be pressed and released within 10 s of successful teach-in. Successful setting is signaled by flashing twice at 1 Hz

Release the teach-in button for < 20 s. If teach-in is

successful, the function indicator (yellow LED) directly

indicates the output state of the sensor. The switching t

hreshold is now optimally set between carrier and label.

The best possible operational safety is provided.

2. End teach-in:

Press the teach-in button for 3 - 20 s. With the

pushbutton pressed down, move several label

with carrier material (label) through the sensor.

The yellow LED flashes at 3 Hz during the

teach-in procedure. Recommendation: Move

at least 3 label + carrier through the sensor.

1. Start teach-in: Position

carrier or label between

the fork

Pushbutton lock

The device can be locked against unintended operation by pressing the teach-in button for > 30 s.

The device can be unlocked by pressing the teach-in button again for > 30 s.

You can change between light switching and dark switching by pressing the teach-in button for 20 - 30 s.

WFS FORK SENSORS

Product description

The slim, forked shape of the WFS has

been specially developed for the require-

ments of the labeling process. The

design allows the sensor to be mounted

directly on the edge of a label dispenser.

Difculty in detecting the label gap is

nally eliminated – the sensor’s switch-

ing threshold can be taught-in while the

label strip is running. This sophisticated

operating concept means the sensor

can be adjusted to different labels

quickly, easily, and reliably. The fast

response time guarantees exceptional

repeat accuracy.

At a glance

• Housing with slim forked shape

• Simple and precise setting of the

switching threshold via IO-Link,

teach-in button, or plus/minus but-

tons

• Light/dark switching function

• Fast response time: 50 μs

• PNP or NPN switching output

• Plastic housing with IP 65 enclosure

rating

• Smart sensor with integrated IO-Link

interface

Your benets

• Flexible and simple mounting directly

on the edge of a label dispenser

ensures a high level of accuracy in

the process

• Small housing allows simple installa-

tion even where space is limited

• User-friendly adjustment allows easy

and quick commissioning

• Fast response times enable precise

detection – even at very high track

speeds

• Thanks to IO-Link or external teach-

in, the switching threshold can be

adapted while the process is running,

increasing process reliability

• Easy to access data from the PLC via

IO-Link
