Alert Statements in this Manual
For users
The F3SJ must be installed, configured, and incorporated into a machine control system by a
sufficiently trained and qualified person. An unqualified person may not be able to perform these
operations properly, which may cause a person to go undetected, resulting in serious injury.
When changes are made to each function using the setting tool (F39-GWUM or F39-MC21), the
administrator must manage the details of the changes and perform the changes. Accidental
functional setting change may cause failure of human body detection, resulting in a serious
injury.
For machines
iv
Do not use this sensor for machines that cannot be stopped by electrical control. For example,
do not use it for a pressing machine that uses full-rotation clutch. Otherwise, the machine may
not stop before a person reaches the hazardous part, resulting in serious injury.
Do not use the auxiliary output or external indicator output for safety applications. Human body
may not be detected when F3SJ fails, resulting in serious injury.
F3SJ-A
User’s Manual
For installation
An actual performance is different according to the state of the installation, the user environment,
and the application. Make sure to test the operation of the F3SJ after installation to verify that the
F3SJ operates as intended. Make sure to stop the machine until the test is complete. Unintended
function settings may cause a person to go undetected, resulting in serious injury.
Make sure to install the F3SJ at the safe distance from the hazardous part of the equipment.
Otherwise, the machine may not stop before a person reaches the hazardous part, resulting in
serious injury.
Install a protective structure so that the hazardous part of a machine can only be reached by a
person that passes through the sensor's detection zone. Install the sensors so that part of the
person is always present in the detection zone when working in a machine's hazardous zones. If
a person is able step into the hazardous zone of a machine and remain behind the F3SJ's
detection zone, configure the system with an interlock function that prevents the machine from
being restarted. Failure to do so may result in serious injury.
Install the interlock reset switch in a location that provides a clear view of the entire hazardous
zone and where it cannot be activated from within the hazardous zone.
Introduction
The F3SJ cannot protect a person from a projectile exiting the hazardous zone. Install protective
cover(s) or fence(s).
To prevent personnel approach to dangerous part of the machine through an zone disabled by
the fixed blanking function, you must install a protective structure to cover the whole disabled
zone. Failure to do so may cause failure of human body detection, resulting in a serious injury.
You must ensure that a test rod is detected for all detection zones except where fixed or floating
blanking function is used. Failure to do so may cause failure of human body detection, resulting
in a serious injury.
Detection capability gets larger when fixed/floating blanking function is used. You must use the
detection capability for fixed and floating blanking functions. Failure to do so may cause failure of
machine stop before reaching the machine's dangerous part, resulting in a serious injury.
You must ensure that the system works as you intended after configuring floating blanking.
Failure to do so may result in serious injury.
Warning zone output is non-safety output. You must not include it to calculation of safety
distance.Otherwise safety distance may be reduced, resulting in serious injury.
A warning zone CANNOT be used for safety applications. Always install your system so that a
detection zone should be passed before reaching a source of danger.
The muting and override functions disable the safety functions of the device. You must ensure
safety using other method when these functions are operating.
Install muting sensors so that they can distinguish between the object that is being allowed to
pass through the detection zone and a person. If the muting function is activated by the detection
of a person, it may result in serious injury.

Introduction
Muting lamps (external indicators) that indicate the state of the muting and override functions
must be installed where they are clearly visible to workers from all the operating positions.
Muting related time must be properly configured for its application by a sufficiently trained and
qualified person, and the person must have responsibility for settings, especially when setting the
muting time limit to infinite.
Use independent 2 input devices for muting inputs.
You must install F3SJ, muting sensor, and physical barrier, and configure time settings for muting
so that an operator should not enter hazardous zone.
Install the switch that activates the override and that uses hold-to-run device, such as springreturn key switch, in a location that provides a clear view of the entire hazardous zone and where
it cannot be activated from within the hazardous zone. Make sure that nobody is in the
hazardous zone before activating the override function.
Install the sensor system so that it is not affected by the reflective surface of the F3SJ.
When using more than 1 set of F3SJ, install them so that mutual interference does not occur,
such as by configuring series connections or using physical barriers between adjacent sets.
Make sure that the F3SJ is securely mounted and its cables and connectors are properly
secured.
Make sure that foreign material such as water, oil, or dust does not enter the F3SJ or the
connector while the cap is removed.
Do not use the sensor system with mirrors in a retro-reflective configuration as shown
below.Doing so may hinder detection. It is possible to use mirrors to "bend" the detection zone to
a 90-degree angle.

Position with detection zone bent at 90
Perform an inspection for all F3SJ as described in "Chapter 6 Checklists". When using series
connections, perform inspections for every connected F3SJ.
For wiring
Connect the load between the output and +24V line (NPN output). Connecting the load between
the output and 0V line will result in a dangerous condition because operation is reversed to "ON
when blocked".
Do not short-circuit the output line to the 0V line. Otherwise, the output is always ON. Also, the
+24V of the power supply must be grounded so that output does not turn ON due to grounding of
the output line.
Configure the system by using the optimal number of safety outputs that satisfy the requirements
of the necessary safety category.
Do not connect each line of F3SJ to a DC power supply of more than 24VDC+20%. Also, do not
connect to an AC power supply. Failure to do so may result in electric shock.
Introduction
For the F3SJ to comply with IEC 61496-1 and UL 508, the DC power supply unit must satisfy all
of the following conditions:
• Must be within the rated power voltage (24V DC
• Must have tolerance against the total rated current of devices if it is connected to multiple
devices
• Must comply with EMC directives (industrial environment)
• Double or reinforced insulation must be applied between the primary and secondary circuits
• Automatic recovery of overcurrent protection characteristics (reversed L sagging)
• Output holding time must be 20ms or longer
• Must satisfy output characteristic requirements for class 2 circuit or limited voltage current
circuit defined by UL508. Refer to p.158 for details.
• Must comply with laws and regulations, regarding EMC and electrical equipment safety, of the
country or region where the F3SJ is used (Ex: In EU, the power supply must comply with the

Chapter1 Application Examples
Overview and Specifications
Using Multiple Sets in Combination
By installing sensors on both sides of a machine as well as in front, you can move workpieces in and
out more efficiently than when a physical barrier is installed. If the sensors are aligned in a U-shape,
series-connection cables can be used between sets (up to 4 sets), so that only one control device is
used, drastically reducing the amount of wiring in the panel.
For a System in which a Workpiece Crosses Detection Zone
(Muting Function)
Enter of a workpiece can be detected by a sensor and the detection zone can be temporarily disabled
only while the workpiece is crossing the whole or specified zone. This function is called muting.
Muting is when a work piece is allowed to enter into a dangerous zone without tripping the F3SJ and
stopping the process. Muting sensors are installed and arranged as to detect the work piece and not a
human entering the zone.

Overview and Specifications
For a System that Has a Machine Within a Detection Zone
When the Zone Is Fixed (Fixed Blanking Function):
For a system in which a fixed facility such as a worktable or a conveyor interrupts specific beams, the
fixed blanking function can be used to disable the specific beams.
When the Zone Is Movable (Floating Blanking Function):
If a part of the machine can move within the detection zone, the floating blanking function can be used
to disable a part of the detection zone.
You can configure a number of beams to be interrupted by an object so that the safety function works
only if more beams than the number are interrupted.

Enhanced Mutual Interference Prevention
When the series connection function is used, mutual interference is prevented in up to 400 beams in 4
sets.
When F3SJ are used individually, the newly designed interference light detection and cycle shift
algorithm prevents mutual interference in up to 3 sets.
The effect of interference between the F3SJ and other photoelectric sensors can be reduced by using
the setting tool to shorten the operating range.
