The FF-SE laser scanner from Honeywell is a revolutionary product in the world of
industrial safety. This device combines radar and laser principles to scan pre-de-
fined zones around dangerous machinery or moving vehicles. In case of intrusion
in these zones, output relays are immediately opened, eliminating the danger.
An infrared class 1 laser beam strikes a mirror rotating at 8 Hz, allowing it to sweep
a 300° area. Any object with a minimum reflectivity of 1,8% (black target) will be
detected in a 6 m / 19.7 ft radius. Two safety levels may be set through two zones
that can have any shape:
• Scanning angle: up to 300°
• Free rotating head, making it a self-
cleaning optical system
• “alarm zone”, in a 10 m / 32.8 ft radius around the FF-SE
• “safety zone” in a 6 m / 19.7 ft radius
These two zones are defined using the software (ordered separately), running on a
computer connected to the FF-SE, which allows the areas to be protected to be
displayed on the screen. The two zones correspond to two independent outputs,
allowing multiple applications:
• Permanent self-checking of the beam
status with fixed test target
• External user defined test target
possibility to ensure correct positioning
of the laser during machine operation
• Response time: 0.280 s
• Surveillance range: 10 m / 32.8 ft
• the alarm zone can be used to trigger an acoustic or light signal when a person
approaches, which indicates that there is a close danger, allowing the intruder to
withdraw without stopping the machine.
• the safety zone is used to trigger the immediate stopping of the machinery
(2 safety NO contacts).
• Detection range: 6 m / 19.7 ft
• Resolution: 70 mm / 2.8 in
at 6 m / 19.7 ft
Restart is automatic after clearing the zone. Use additional safety control module if
manual restart is needed.
TYPICAL APPLICATIONS
• Horizontal detection (like a sensitive
mat) of people or objects
This system is unique because of its small resolution (0,5° in angle) and its excel-
lent precision, while covering a wide area (262 m2 / 2820 ft2). The FF-SE has been
designed in agreement with the pr EN 61496-3 that will soon be brought into effect
for this new kind of detecting device.
• Anti-collision system for AGVs
External and internal surveillance systems make it a Type 3 optoelectronic protec-
tive system. Its self-cleaning optical head and its good immunity to pollution guar-
antee a superior reliability.

The protection zone is made up of 600 beams. Each beam re-
ceives a signal corresponding to a distance measured using the
light time of flight principle, whatever the reflectivity of the tar-
get. If this signal goes below a user defined threshold during
the surveillance, it means that an object is present in the protec-
tion area. Consequently, the corresponding relay is opened.

Applications: a greater flexibility
The FF-SE being an optoelectronic detecting device, it has a no
touch detection and therefore brings more flexibility on site. Its
principle of diffuse reflection simplifies the installation, com-
pared to the traditional emitter/receiver pair of light curtains.
The protection zones do not need any additional fixture (wall,
fence, door...) since the FF-SE covers a 300° angle and adapts
to existing obstacles. Installation costs are reduced to a mini-
mum and the working position is easily accessible since the
protection is a no-touch type.

In case of a change in the machine or production floor layout,
the FF-SE can adapt very quickly by a re-configuration. The
FF-SE is not linked to any particular set up or machine: it is
exchangeable just by programming.

S ≥ V (t1 + t2) + (L - 0.4 H) + E
Compared to a usual safety device (light curtain, safety mat,
door...), the FF-SE includes two protection zones which is a
great asset: the alarm zone, used as an early warning zone,
allows a signal to an intruder that he is close to a dangerous
zone and that his movement is about to stop the machine.
There is still time for the individual to change direction and
avoid a stoppage of the equipment that can be costly if it
occurs often. By avoiding unnecessary stoppage, the FF-SE
increases the production lines productivity without decreasing
the safety: it protects just what is needed.
Where:
• S: Distance (mm / in)
• t1: Response time of the FF-SE (See technical
specifications)
• t2: Stopping time of the machine (s); i.e. the time interval
necessary to stop the machine, after the protection
device has emitted the stop signal
• L: 1200 mm / 47.28 in
• H: Height of the beam from the ground,
300 ≤ H ≤ 1000 mm / 11.82 ≤ H ≤ 39.4 in
• V: Penetration velocity (mm / s or in / s)

Software
Graphic screen
The Honeywell software kit allows the protection zones to be
easily programmed into the sensor. This software runs under
any PC (286 or more), under MS DOS. The FF-SE is linked to the
PC through the serial port (RS232 format) and a cable supplied
with the software kit. The custom zone definition can be
achieved through 3 different methods that can be combined:
• with the mouse, by clicking on end points forming the limit of
the protection field;
• with the keyboard, by plotting points with the cursor keys;
• with a text editor in which the end points are defined by their
coordinates;
Defining the protection zones is easy since obstacles are dis-
played on the screen: they are seen in real time.
Using a PC also allows to store several configurations on a disk,
that can be retrieved in a few seconds into the sensor. One can
therefore define different shapes according to different situa-
tions and transmit them into the sensor whenever needed.
Once the settings are downloaded into the sensor, it is a
standalone device that will keep all zone definitions and param-
eters in a permanent memory, even if the power is cut. Access
to this memory and to zone definition is protected by a pass-
word. The program also has other features: real time profile
measurement, sensor simulation to get familiar with it, surveil-
lance of the zones with intrusion time display.
Defining the zones with the editor
Self-check
A fixed test target is mounted on top of the housing to ensure
the beam self-check: this takes away 60° off the scanning angle
to perform various checks: contamination of the lens, accuracy
of the distance measurements, status of the beam...
Example of electrical connection
An external test target possibility ensures the correct position-
ing of the sensor and guarantees the safety if its position is
changed since the definition of the zones depend on the posi-
tion of the sensor. The rotating head is self-cleaning and there-
fore is much less sensitive to pollution as other fixed-window
devices. The internal angular coder is controlled by a “surveil-
lance circuitry”, as are the relays.

a better coverage and an increased flexibility. Its small size
allows installations in most of existing sites. The laser beam is
an invisible Class 1 laser, therefore it is not harmful and does
not disturb workers. A unique connector links the sensor to the
power supply and the devices connected to the 3 output relays
(alarm, safe 1 and safe 2), making connections with the sensor
very easy.

For AGVs
No intrusion
Normal speed
Slowing down
Complete stop
Weight and speed of AGVs in industrial environments can rep-
resent a certain danger for the workforce. The FF-SE can be
installed on these AGVs to ensure people safety: due to its long
range, it can stop the AGV before the obstacle, even if its speed
is high.
The two distinct zones can be used in an elegant way:
The alarm zone, with its 10 m / 32.8 ft range, acts as a slowing
down system: if something is detected in the zone, the AGV will
slow down and emit a warning signal to make the way free
again.
Intrusion
in the alarm zone
The safety zone, with its 6 m / 19.7 ft range, acts as an emer-
gency stop: the AGV will immediately be stopped when an ob-
ject is detected in this zone.
Intrusion
in the safety zone
Knowing the AGV stopping distance and the response time of
the safety chain, it is possible to calculate the limits of these
zones optimally.

• FF-SEZ6BRAC3 Mounting bracket: It reinforces the
protection in installations where the sensor could be reached
by humans or vehicles. It allows head up or down mounting.
The bracket can be mounted on a vertical surface from behind
thanks to 4 M6 holes. There are 2 adjustable screws that allow
an adjustment of the scanning plane (±8°) in X, ± 4° in Y, so as
to allow an accurate placement of the beam, especially in
multiple device configurations.
