If a problem occurs,
the F3SN-A/F3SH-A ensures
that the machinery will stop
by outputting the same OFF
signal as when an intrusion
is detected.
We pursued the safety of F3SN-A/F3SH-A to the limit with
the mutual check of two CPUs, safe design by dual circuits
of signal control and output, and FMEA*, which verifies
the safety of the operations.
*FMEA : Failure Mode & Effects Analysis

IEC61496-2 and UL Listing for Canadian safety standards. Can be
used with machinery that will be used under OSHA regulations
(29 CFR 1910. 212), which are stipulated under the Occupational
Safety and Health Act of 1970. Also fulfills the requirements for
ANSI/RIA R15.06-1999, the United States Safety Requirements
for Industrial Robots and Robot Systems. The F3SN-A/F3SH-A

Compact Sensor
OMRON has successfully developed a compact Sensor
surface area (30 30 mm) in a Type 4 Safety Light Curtain
with built-in amp. The new F3SN-A/F3SH-A is 25% smaller
than earlier OMRON models.
Select the Perfect Length
Select a detection capability of either 14-mm diameter
(Beam gap: 9 mm) or 25-mm diameter (Beam gap:
15mm). For the 14-mm diameter type, OMRON has
created 53 models, at 18-mm intervals (all odd-numbered
beams from 21 beams = 189 mm to 125 beams = 1,125
mm). For the 25-mm diameter type, OMRON has created
108 models, at 15-mm intervals (all beams from 13 beams
= 217 mm to 120 beams = 1,822 mm).

Connect up to 3 sets in series.
Prevents mutual interference.
Up to 3 sets can be connected in series by using both
the standard model and a series-connection model with
a connector. You can create a 3-set system by just wiring
one set – no need to wire three sets separately as was
required with earlier models. This facilitates protection
for all dangerous machine and device surfaces. Mutual
interference is also prevented.

Easy Function Settings, Monitoring,
and Copying to Multiple Sensors
In earlier Sensor models, function settings were made using an internal DIP switch,
and switch operation used to be very difficult after Sensor was mounted.
That's why we added a Setting Console.
Just connect the Sensor Cable when it is time to make the function settings and
you can easily make blanking and all other settings directly from the Setting Console.

Two Types of Blanking Functions
Blanking functions change the Safety Light Curtain detection patterns.
Basic Pattern 2: Fixed Blanking
Uses a teaching technique to mask and disable
specific beams. Ideal for applications where part of a
machine or jig is always inside the fixed detection
zone of the Safety Light Curtain.
Basic Pattern 1: Floating Blanking
Disables detection for 1, 2, or 3 non-specific beams.
Output is turned OFF if more than the specified
number of beams are obstructed. Ideal for applications
where a robot arm for removing workpieces passes
through the Safety Light Curtain detection zone at
irregular intervals.
Auxiliary Output: Can select outputs such as Dark-ON,
Light-ON, Light diagnosis, and Lockout.
External Indicator Output: Can select external indicator output from Dark-ON,
Light-ON, Light diagnosis, and Lockout.
EDM (External Device Monitoring) function: Monitors for external relay contact welding.
Interlock Function: Sets interlock for when power is turned ON or the system is restarted.
Copy Settings Function: Copies Sensor settings to another Sensor.
Protect Function: Prohibits or limits changes to Sensor settings.
7
Other Function Settings from the Setting Console
There is a danger if fixed blanking
is not used because a hand
could enter under the
light curtain if the work
bench shifts out of
the zone.
If fixed blanking is used and the work
bench is removed, fixed blanking
will be canceled. If, for example,
a hand enters the area,
it will be detected and the
output will be turned OFF
for safety.
A protruding part fixed on a moving
die moves up and down within the
detection zone.

The F3SH-A enables human body detection using the 4-beam
dimensions recommended by EN Standards.
300-mm gap using 4 beams. Detects whole-body intrusion.
The EN999 Standard concerns machine safety, in particular the positioning of protective devices in
relation to the approach speed of part of a human body. The values in the table indicate the heights from
the reference surface (such as the floor) for each beam of a 4-optical-beam Sensor recommended as
most effective under EN999. The F3SH-A Beam gap matches the recommended dimensions and can,
therefore, detect intrusion under the lowest beam or over the
highest beam, for settings shown in the following diagram.
