Achieving a new standard of safety assurance:
SUNX proves the reliability of the SF4-AH series,
through compliance with international standards.
Upon the enactment of “ISO 12100”, which is based on European Standards
(ENs), there are now urgent requirements for the industry to establish safety
standards in accordance with technological innovations.
Even as this interest in safety has been growing, the SUNX / SF4-AH series has
been dedicated to the complete pursuit of safety and has achieved the highest
safety standards.

Reduced requirements for safety distance calculations
As a high-speed 11 ms response has been achieved, regardless of the
number of beam channels, the calculation of safety distances for each
individual sensor is no longer necessary. This high-speed response
simplifies the entire process of safety distance calculation.
Increasing the safety distance response speed allows the safe distance
between the danger areas and the light curtain to be reduced, thus
allowing for miniaturization of the equipment.

A safety light curtain that can be used in a variety of work environments
Providing ‘safety + ’ to every workplace in the world
The SF4-AH series integrates reliability, economy and ease of
installation, with excellent specifications, fully compliant with Safety
category 4 .
This versatile light curtain is well suited for a wide variety of safetyrelated applications, allowing it to be utilized by almost any
workplace.
Unaligned beam axes can be seen at a glance
The beam-axis alignment indicators are distributed on the sensors
in four sections. As the indicators of the sections whose beams
are aligned light up in red, allowing the user to easily verify which
beam axes have become aligned. Once all beams have become
aligned, the indicators light up in green. Upon the beginning of
alignment, as soon as the bottommost or the topmost beam axis
(the standard beam axis) becomes aligned, then the
corresponding bottommost or topmost alignment indicator light will
begin blinking red. Therefore, beam axes can be easily aligned by
performing the initial beam axis alignment on either the
bottommost or the topmost beam axis, then rotating the light
curtain around the axis
of this beam. The
beam-axis alignment
indicators are provided
on both the emitter
and the receiver, so
that you can see at a
glance which beams
are not aligned.

Even though some beam channels are aligned, the user cannot
determine which beam channels are aligned
(Cannot determine which beam axes are not aligned)
Even though beam channels are only partially aligned, the user can
determine which beam channels are aligned
(Beam axes of two upper blocks are aligned / beam axes of two lower blocks are not aligned)
Only the bottommost channnel beam axis is correctly aligned
Only the beam axes of the two lower blocks are correctly aligned

Alignment of beam axes can be accurately performed prior to power-up
If the SF-LAT-2N Laster Alignment Tool is
utilized, then beam axes alignment can be
quickly and easily performed, using the
easy-to-see laster beam spot, even when
light curtain units are installed long distances
apart. In addition, as the SF-LAT-2N Laster
Alignment Tool is battery-operated; beam
axes alignment can be performed before
actual power-up of the light curtain itself.

Mounting bracket enables
easy beam-axis alignment
The beam-axis alignment is easy since angle
adjustment is possible with the enclosed
rear mounting bracket (MS-SF2N-1). Furthermore, the optional side mounting bracket
(MS-SF2N-3) can also be used for side
mounting.
Rear mounting bracket
Incorporates advanced ELCA function that prevents mutual interference and
reduces interference from extraneous light
Recognizes extraneous light
and prevents malfunctions
Mutual interference is reduced without the
need for interference prevention lines
This function allows the sensor to recognize and reject
interferences of instantaneous extraneous light emitted
from peripheral equipment, thus preventing malfunctions
caused by a variety of sources, including: other sensor
beams in the vicinity of the operating sensor, beam
spatter, AGV and rotating light sources. By reducing the
number of malfunctions caused by extraneous light,
detection operations will be interrupted less frequently,
resulting in tremendous improvements to work efficiency.
The ELCA (Extraneous Light Check & Avoid)
function enhances the mutual interference
prevention function.
ELCA decreases interference from extraneous light having a similar frequency as the
light used by the SF4-AH series, thereby also
minimizing mutual interference among nearby
SF4-AH series sensor units.
The SF4-AH series is equipped with emitting
light amount control function, thus minimizing
interference with peripheral sensors
Reducing the amount of light emitted from the
emitter facilitates the minimization of any effects of
such emitted light on peripheral equipment. (This
function can be selected by using the Handycontroller.)
Reducing mutual
interference
High immunity to interference
from extraneous light
Reductions in total costs are possible by using series connections
Using the optional serial connection cable, a maximum of 3 sets of
sensors can be connected in series. Previously, separate wiring was
required for 3 sets of sensors. But now, wiring equivalent to that for only
one set is required, thus saving troublesome wiring and costs. As well,
fewer power connections are required, thus reducing the number of
safety relay units needed to a single unit, resulting in tremendous cost
reductions.
Series connection cables are available
in lengths of up to 3 m 9.843 ft!
Up to three sets can
be connected in series

Front protection cover protects the sensing surface
Our product line-up now includes a Handy-controller
that enables the user to select a variety of settings.
Function settings can be easily performed by anyone.
In the event that the SF4-AH series is installed in a harsh
environment, the use of the front protection cover (FC-SF4A-H□,
optional) will protect the sensing surface from damage.
Any valid beam channels can be selected!
The SF4-AH series now incorporates a fixed blanking function.
Thorough sensor protection measures
have also been implemented
Front protection cover
The SF4-AH series is equipped with a fixed blanking function that allows specific
beam channels to be selectively blocked, without causing the control output
(OSSD) to output the OFF signal. This function is convenient for use with
applications in which certain fixed obstacles always block specific beam channels.
Furthermore, this function provides greater safety, as the control output (OSSD)
will automatically output the OFF signal if the fixed obstacles are subsequently
removed from the sensing area.
Impact protection for the sensing surface
A front protection unit is now available that will prevent damage to
the sensing surface, due to impacts from objects sensed
(optional).
Front protection unit
Spatter protection for the sensing surface
The spatter protection hood type, now
available, protects the sensing surface from
welding machine spatter. Moreover, a front
protection cover that can be installed within
the sensor casing is also available,
completely preventing spatter from adhering
to the sensing surface.
In addition, even though sensed objects
may contact the sensor, the sensing surface
will be protected. As well, the ELCA
function implements all possible measures
to prevent malfunctions caused by spatter.
Front protection cover
Automatic blanking of beam channels!
The SF4-AH series now incorporates a floating blanking function.
1, 2 or 3 non-specified beam channels can be deactivated. If the number of beam channels
that are blocked is less than or equal to the number of preset beam channels, then the
control output (OSSD) will not output the OFF signal. This function is useful in the event
that the positions of obstacles within the sensing area must be changed during work-piece
re-arrangement, or when material must be thrown through the light curtain’s sensing area.
Minimum size of objects detected
When 1 beam channel has been preset: "50 mm "1.969 in
When 2 beam channels have been preset: "70 mm "2.756 in
When 3 beam channels have been preset: "90 mm "3.543 in

Monitoring function This function allows the user to confirm the
of settings details details of each sensor setting.
Protection
This function locks the sensor using a fourfunction
digit password. This function will not allow
changes to sensor function settings unless the
password is input, thus preventing third parties
from accidentally changing the settings.
Copy function
Allows settings details to be copied into
other sensors. In the event that the same
setting must be input several times into
different sensors, this function will reduce
the time required for the input of settings.

The SF-AC, a exclusive safety relay unit for the light curtain, will be also available
Safety will be enhanced even further
A separate power supply and connecting terminal blocks are not needed
As SF-AC incorporates a power supply for the light curtain, as well as terminals for
synchronization lines, neither a separate power supply nor terminal blocks are required.
A separate power
supply is not required!
Connecting terminal
blocks are not required!
Installation time and labor can be
saved due to the usage of
detachable terminal blocks
As wiring can be performed with the terminal
blocks removed, it is not necessary to detach
the controller from the control panel when
performing maintenance, thus reducing the
number of installation procedures required.
Incorporates a 2-channel auxiliary output
Maintenance free
SF-AC incorporates both an auxiliary output that operates together with the light curtain’s
OSSD, and an alarm output that functions together with the light curtain’s auxiliary output
(non-safety output). These features allow for monitoring of light curtain activity.
As SF-AC employs hybrid fuses, fuse
replacement is not necessary.
10 ms high-speed response
The fastest response time for a relay
output, 10 ms, has now been achieved.

Wiring
Others
• Make sure to carry out the wiring in the power supply off condition.
• Verify that the supply voltage variation is within the rating.
• If power is supplied from a commercial switching regulator,ensure
that the frame ground (F.G.) terminal of the power supply is
connected to an actual ground.
• In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this sensor, connect the frame
ground (F.G.) terminal of the equipment to an actual ground.
• Do not run the wires together with high-voltage lines or power lines
or put them in the same raceway. This can cause malfunction due
to induction.
• Do not use during the initial transient time (2 sec.) after the power
supply is switched on.
• Avoid dust, dirt and steam.
• Take care that the sensor does not come in direct contact with
water, oil, grease, or organic solvents, such as, thinner, etc.
• Take care that the sensor is not directly exposed to fluorescent light
from a rapid-starter lamp or a high frequency lighting device, as it
may affect the sensing performance.
