High level of safety achieved
The SF2-N series have the same level of
safety built into the sensor body as
conventional fail-safe type area sensors,
and conform European and North American
safety standards. So, they can be used in
workplaces throughout the world.
The sensor carries out self-diagnosis when it is turned ON.
The monitoring section (CPU) which is inside the emitter constantly checks the
emitting circuit and the control circuit. Furthermore, the receiver also has a
monitoring section (CPU) which constantly checks the receiving circuit, control
circuit and output circuit, so that a high level of safety is maintained at all times.
Europe
North
America
CE marking based on Machine Directive and EMC
Directive has been obtained, so that the sensors
can be used in Control Category 2 equipment.
Type 2 based on IEC 61496-1/2, EN 61496-1
and Control Category 2 based on EN 954-1
C-UL US listings (UL 61496-1/2) which
are required for use in the United States
and Canada have been obtained.
Safety design of the SF2-N series
The sensor switches to the lockout mode when an error occurs, so that the OSSD (control output)
and alarm output turn OFF.
Two output transistors are connected in series to provide duality, so that the sensor also locks out
if one of the transistors is short-circuited.
Self-diagnosis using test input allows detailed checking such as overlapping emission (overcurrent
error), light emission strength, etc.

Wire-saving by series connection
Using the optional serial connection cable,
a maximum of 3 sets of sensors with a
total of 128 beam channels (for 20 mm
0.787 in beam pitch type) or 64 beam
channels (for 40 mm 1.575 in beam pitch
type) can be connected in series. Hence,
even L-shaped and U-shaped areas can
be easily covered. 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.

The design is compact, with a width of
only 28 mm 1.102 in and a thickness
of 19 mm 0.748 in. The small amount
of space needed allows the sensors to
be incorporated into the machinery.
The beam-axis alignment indicators are distributed on the sensors in four
sections. The indicators of the sections whose beams are aligned light up in red,
and when all beams are aligned, the indicators light up in green. 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.

The ELC (Extraneous Light Check)
function prevents malfunction due to
extraneous light, such as from other
nearby passing sensors, AGVs, patrol
lights or spatter light.
mWhat is the Extraneous Light Check (ELC) function?
This function distinguishes between light from the
sensor itself and light from extraneous sources, and
reduces the effect of the extraneous light if it is
received by the sensor.

Different types for different needs
There are sensors having a beam pitch of 20 mm 0.787 in (detection capability "30 mm "1.181 in)
and a protective height ranging from 190 mm 7.480 in (8 beam channels) to 1,310 mm 51.575 in
(64 beam channels). Plus, there are sensors having an beam pitch of 40 mm 1.575 in (detection
capability "50 mm "1.969 in) and a protective height ranging from 190 mm 7.480 in (4 beam
channels) to 1,630 mm 64.173 in (40 beam channels). The sensors can be selected from this wide
variety to suit your requirement. PNP output types are also available for all models.

Spatter protection for the sensing surface
Front protection cover protects 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.
The optional front protection cover
(FC-SF2N-A / FC-SF4A-H-H) can
be fitted to the sensor to protect the
sensing surface even when using the
sensor in poor environmental conditions.

By using the optional slit mask
(OS-SF2N-A / OS-SF4A-H-H), the
amount of beam emitted or received
can be restrained to reduce the effect of
extraneous light from other sensors, etc.
The beam-axis alignment is easy since
angle adjustment is possible with the
enclosed rear mounting bracket
(MS-SF2N-1). Alternatively, the side
mounting bracket (MS-SF2N-3) is also
available as an option.

By using the SF-LAT-2N laser alignment
tool, you can quickly and easily align
beam axes. The laser beam spot is easy
to see, even when light curtain units are
installed far apart. In addition, as the
SF-LAT-2N laser alignment tool is
battery-operated, beam axes can be
aligned before powering up the light

hence reduces the interference
between neighboring sensors.
It is also used in cases when the
beam intensity is too strong

In order to maintain safety, carry out the self-diagnosis
at least once a day.
• If the test input is kept open for 28 ms, or more, detailed diagnosis, in
addition to the internal self-diagnosis being done during normal operation,
is carried out. In case no abnormality is discovered during self-diagnosis,
and if the test input is continued to be kept open after that, emission halt
state is achieved. In case an abnormality is discovered during selfdiagnosis, the device is put in the lockout state at that instant, and the
control output (OSSD) and alarm outputs are fixed at the OFF state.
• Emission halt state is achieved when no abnormality is detected
during self-diagnosis and the test input is continued to be kept open
after that. During emission halt, control output (OSSD) and alarm
output switch to the OFF state. By using this function, malfunction
due to extraneous noise, or abnormality in control output (OSSD)
and alarm output, can be determined even from the equipment side.

Series / Parallel mixed connection (Series connection: 3 sets, parallel connection: 2 sets connectable)
• The series / parallel mixed connection method supports the use of multiple emitters and receivers,
connected in combinations of both series and parallel connections. This method can be utilized when
there are two danger regions or more and when there are two entrances or more to the danger regions.
For all series connections, outputs will move to the OFF state if beams for any of the beam channels
are interrupted. However, as the outputs of the parallel connections are separate, if beams from any
pair of parallel sensors are interrupted, outputs from all other parallel sensor pairs remain unaffected.
