G-6 Safety Sensors / Components
Features
The setting console--the first in the industry--allows you an easy and safe setting of various
functions.
Includes two types of blanking functions
Blanking function for changing the detection pattern of the
safety light curtain.
Basic pattern 1: Floating blanking function
This function allows you to disable an unspecified 1, 2, or 3
optical axes. If more than the set optical axes is interrupted,
the output shuts off.
(Example of floating blanking function)
Basic pattern 2: Fixed blanking function
Specific optical axes are masked by teaching and disabled.
(Example of fixed blanking function)
Other functions to be set with the setting console
●Auxiliary outputs: Outputs such as ON at Dark, ON at Light,
light intensity diagnosis, and lockout can be selected.
●Large indicator lamp outputs: large indicator lamp outputs
can be selected from ON at Dark, ON at Light, light inten-
sity diagnosis, and lockout.
●External device monitoring function: Allows you to monitor
the feedback of external devices.
● Interlock function: Interlocks can be set at power-on and restart.
●Setting copy function: Allows you to copy the settings of one
sensor to another sensor.
●Protect function: Changing of sensor settings can be pro-
hibited and restricted.

Floating-and-blanking function
However, nullification of
mere optical axis will
remain as it is, even if
the work piece was removed.
Since it is undetectable even
if a hand invaded, it is dangerous.
Optical axis can be shaded
and disabled when a work
piece is in detection area.

Fix Blanking Function
The fix blanking function with F3SN,
the instant the work stand removed,
resets blanking, and the invalid
optical axis returns effectively.
Since it is detectable even if a hand
invaded, it is safe.

F3SN-A/F3SH-A
F3SH-A Multi-beam safety sensor
Recommended dimensions of EN standard for
F3SH-A (4-optical axis multi-beam)
Human body detection achieved
4 optical axes at a 300 mm pitch. Detects break by entire
body.
In EN Standard EN999 (machine safety: positioning of protec-
tive devices in relation to the approach speed of human body
parts), the values in the following table are recommended as
the most effective regarding the height from the reference sur-
face (floor, etc.) of each optical axis of the 4 optical axis multi-
beam sensor.
The optical axis pitch of the F3SH-A matches the recommend-
ed pitch, and, thus, in the installation shown in the following di-
agram, every type of intrusion is detected, including intrusion
by passing under the lowest optical axis and intrusion by
passing over the highest optical axis.
(Installation example based on EN999 recommended dimen-
sions for multi-beam safety sensors)
Easy safety application
Various safety functions are implemented.
Can be adapted to various safety circuit system
configurations.
●Interlock function
●Auto reset / manual reset can be selected
●External device monitoring function
Equipped with LED bar for easy use.
Easy optical axis adjustment using LED displays. En-
ables certain installation.

G-18 Safety Sensors / Components
Detection zone and intrusion path
F3SN-A Safety Light Curtain
Install protective structures around the machine so that you must
pass through the detection zone of the F3SN-A to reach a hazardous
part of the machine.
Install the F3SN-A so that some part of the operator’s body remains
in the detection zone at all times when the operator works in a haz-
ardous area. Failure to do so may result in serious injury.
Correct Installation
Incorrect Installation
F3SH-A Multi-beam Safety Sensor
Install protective structures around the machine so that you must
pass through the detection zone of the F3SH-A to reach a hazardous
part of the machine.
If it is possible for an operator to get between the sensor’s detection
zone and the hazardous part of the machine, design the system so
that machinery cannot start up automatically. Make sure that machin-
ery cannot restart while the operator is in the hazardous area. Posi-
tion the switch for restarting machinery in a location from which the
status of the hazardous area can be seen clearly. The switch position
location must be a place where the switch cannot be operated from
within the hazardous area.
Failure to do so may result in serious injury.
Use of the fixed blanking function
After setting the fixed blanking, check that the F3SN-A detects a test
rod at any position in the detection zone through which a person can
reach the hazardous part of the machine. If any positions are found
by check above, install protective structures to prevent intrusion,
which the F3SN-A can not detect.
Failure to do so may result in serious injury.
Distances from reflective surfaces
Be sure to install the F3SN-A/F3SH-A to minimize the effects of re-
flection from nearby surfaces.
Failure to do so may cause detection to fail and may result in serious
injury.
Install the F3SN-A/F3SH-A with minimum Distance D shown above
from reflective surfaces (highly reflective surfaces) such as metal
walls, floors, ceilings, and work pieces.
Safety distance
Always maintain a safe distance (S) between the light curtain and a
hazardous part of a machine.
Failure to do so causes the machine to fail to stop before an operator
reaches the dangerous area and may result in serious injury.
Use of the floating blanking increases the size of the detection capa-
bility. To calculate a safety distance, be sure to use the increased size
of the detection capability.
Failure to do so causes the machine to fail to stop before an operator
reaches the dangerous area and may result in serious injury.
The “safety distance” is the minimum distance that must be main-
tained between the F3SN-A/F3SH-A and a hazardous part of a ma-
chine in order to stop the machine before someone or something
reaches it. The safety distance is calculated based on the following
equation when a person moves perpendicular to the detection zone
of a light curtain.
Safety distance (S) = Intrusion speed into the detection zone (K)
× Total response time for the machine and light curtain (T)
+ Additional distance calculated based on the detection
capability of the light curtain (C) .......................................... (1)
The safety distance varies with national standards and individual ma-
chine standards. The equation is also different if the direction of in-
trusion is not perpendicular to the detection zone of the light curtain.
Be sure to refer to related standards.
F3SN-A Safety Light Curtain
Reference

EN999 (for intrusion perpendicular to the detection zone)
Detection capaibility: 40mm or less
Substitute K = 2000 mm/s and C = 8 (d – 14 mm) in equation (1)
and calculate as shown below.
S = 2000 mm/s × (Tm + Ts) + 8 (d – 14 mm) ......................... (2)
Where: S = Safety distance (mm)
Tm = Machine response time (s) (See note 1)
Ts = Light curtain response time (s) (See note 2)

d = Detection capability of the light curtain (mm)
e. g.:
Tm = 0.05 s, Ts = 0.01 s, d = 14 mm:
S = 2000 mm/s × (0.05 s + 0.01 s) + 8 (14 mm – 14 mm) =
120 mm
Use S = 100 mm if the result of equation (2) is less than 100 mm.
Recalculate using the following equation with K = 1600 mm/s if the re-
sult is over 500 mm.
S = 1600 mm/s × (Tm + Ts) + 8 (d – 14 mm)..........................(3)
Use S = 500 mm if the result from equation (3) is less than
500 mm.
Detection capability: over 40mm
Substitute K = 1600 mm/s and C = 850 mm in equation (1)
and calculate as shown below.
S = 1600 mm/s × (Tm + Ts) + 850
Where: S = Safety distance (mm)
Tm = Machine response time (s) (See note 1)
Ts = Light curtain response time (s) (See note 2)
e. g.:
Tm = 0.05 s, Ts = 0.01 s:
S = 1600 mm/s × (0.05 s + 0.01 s) + 850 mm = 946 mm
Note: 1 .The machine response time refers to the maximum time from the mo-
ment the machine receives a stop signal to the moment the hazardous
part of the machine stops. The machine response time should be
measured on actual machines. The machine response time should be
measured and confirmed periodically.
Response Time Table
• Response time for series connected types is calculated
as follows: (F3SN-A)
For 2 sets:
Response time (ON to OFF): Response time of Light
curtain 1 + Response time of Light curtain 2 + 3 ms
Response time (ON to OFF): Response time of Light
curtain 1 + Response time of Light curtain 2 + 12 ms
For 3 sets:
Response time (ON to OFF): Response time of Light
curtain 1 + Response time of Light curtain 2 +
Response time of Light curtain 3 + 4 ms
Response time (ON to OFF): Response time of Light
curtain 1 + Response time of Light curtain 2 +
Response time of Light curtain 3 + 16 ms
• Response time of F3SP-B1P is 10 ms, operation time is
100 ms.
1 .The light curtain response time refers to the time required for output to
change from ON to OFF.
2 .When using the F3SP-B1P, determine the safety distance by adding
the response time of the F3SP-B1P to that of the F3SN given in the
table above.
Reference
Method for calculating the safety distance as provided by ANSI B11.
19 (US)
Safety distance (S) = Intrusion speed into the detection zone (K)
Response time (Ts + Tc + Tr + Tbm) + Additional distance (Dpf)
Where:
K = Intrusion speed (Recommended value in OSHA stan-
dards
is 1600 mm/s)
ANSI B11. 19. does not define Intrusion speed (K). When de-
termining K, consider possible factors including physical ability
of operators.
Ts = Time required for machine to stop (s)
Tr = Light curtain response time (s) (See note)
Tc = Maximum response time required for machine control
circuit to apply brake (s)
Tbm = Additional time (s)
If the machine is provided with a brake monitor, Tbm = brake
monitor setting time – (Ts + Tc). If not provided with a brake
monitor, it is recommended to determine a value more than 20%
of (Ts + Tc) as the additional time.
Dpf = Additional distance.
Dpf is calculated as follows based on ANSI standards:
Dpf = 3.4 × (d – 7.0) where d is the detection capability of the
light curtain (mm).
e. g.:
Assume that: K = 1600 mm/s, Ts + Tc = 0.06 s,
Brake monitor setting time = 0.1s, Tr = 0.01s, d = 14 mm.
Then:
Tbm = 0.1 – 0.06 = 0.04 s
Dpf = 3.4 – (14 – 7.0) = 23.8 mm
S = 1600 × (0.06 + 0.01 – 0.04) + 23.8 = 199.8 mm
Note: The light curtain response time refers to the time required for output to
change from ON to OFF.

Assume that the sensor is installed with the lowest beam height
above the floor at 300 mm and the highest beam height above
the floor at 1200 mm, with the diameter of the smallest detect-
able object being 64 mm or less. Then, Dpf is determined from:
Dpf = 3.4 × (Os – 6.875 mm).
If the diameter of the smallest detectable object is more than 64
mm, Dpf is calculated to be 900 mm.

Installation
How to prevent mutual interference
The emitter and the receiver to be set facing each other should be a
pair of the same set. Erroneous combination may create a zone
where objects cannot be detected.
Do not use the sensors for a system where the beam is reflected, or
object detection may be disabled. In such an application, use a beam
path diversion mirror to prevent the beam reflected from an object
from entering the receiver.
When installing two or more pairs of the F3SN-A/F3SN-B/F3SH-A,
take necessary measures to prevent mutual interference. Examples
of such measures include electrical interconnection and the use of
baffle plates.

How to prevent mutual interference
Series connection (Up to 3 sets, 240 beams, sensor models ending
in -01, -03, -04, and -05 are required for series connection)
Two or more pairs of the F3SN-A can be connected in series. When
connected in series, the F3SN-A sensors generate beams in a time-
sharing manner. Thus, they prevent mutual interference and ensure
safety.
When not connected
When installing two or more pairs of light curtains independently from
each other due to inconvenience of wiring or other reason, take prop-
er measures to prevent mutual interference. If mutual interference
occurs, a lockout condition will result for the F3SN-A/F3SH-A.
• Installation which may cause mutual interference
• Installation to prevent mutual interference
(1) Install so that the two light curtains emit in the opposite directions
(staggered).
(2) Install a light interrupting wall in between sensors.
