series complies with the IEC 61496-1/2 international standards, so that it can be used in different countries
throughout the world.
•
CE marking based on Machine Directive and EMC Directive has been obtained.
[Type 4 based on IEC 61496-1/2, EN 61496-1, and Control Category 4 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.
•
This series is also compatible with equipment conforming to OSHA (1910.212/217), ANSI (B11.1lB11.20) and ANSI / RIA
15.06 regulations.
Pursuit of safety
It uses two independent CPUs, which mutually check the
safety conditions. High reliability fail-safe design is realized
by incorporating dual circuits for signal processing and
output.
•
•
Further,
•
in order to ensure safety, FMEA (Failure Mode &
•
Effects Analysis) has been used to prove safe operation.
Safety design of the SF2-EH series
The sensor unit continually performs self-checking on its
internal circuitry, its cable integrity and even checks for
interference from extraneous light.
In the event of any fault or malfunction, the sensor
outputs the same signal (OFF signal) as is produced
during actual beam detection operation.

SF2-EH
Exclusive controller not required
Since an exclusive controller is not required, there is no need to provide space for
it. Further, the PNP output equivalent type can be combined with an optional
safety relay unit (SF-AC) to create an intrusion detection system.
Wide area: 1,580 mm 10 m
62.205 in 32.808 ft
It realizes a wide sensing area with a
protective height of 1,580 mm
62.205 in
max. (80 beam channels) and a long
operating range of 10 m
32.808 ft.
Just one sensor can cover an area
where previously 2 sensors had to be
used.
Sensors connectable in series
Using the optional cable (SF2-CSL )
for series connection, maximum 4 sets
of sensors with a total of 192 beam
channels can be connected in series.
For example, in case of mounting the
sensors on the front, as well as, both
the sides of a danger region, previously
separate wiring was required for 3 sets
of sensors. But now, wiring equivalent
to that for only 1 set is required, thus
saving troublesome wiring and cost.
Wide variety
There are 13 models of sensors having
a
protective
height
ranging
from 220 mm
8.661 in
to 1,580 mm
62.205 in
(12 to 80 beam channels).
The sensors can be selected to suit
the monitoring area of the used
equipment.
Further, PNP output equivalent type,
as well as, NPN output equivalent type
are available.
No interference
•
Up to 12 sets of sensors can be
mounted close together
•
In case of series connection or parallel
connection, interference can be prevented
for up to 4 sets, respectively. Further, in
case of series and parallel mixed
connection, up to 12 sets (total 192 beam
channels) can be mounted close together.
•
Effective aperture angle 2.5 or less
•
Since the effective aperture angle is
narrow ( 2.5 or less), it reduces
the effect of reflection from walls, etc.,
and interference from extraneous
light.
•
Convenient slit mask available
•
By using the optional slit mask
(OS-SF2-H ), the amount of beam
emitted or received can be restrained
to reduce the effect of extraneous
light from other sensors, etc.
Easy maintenance
An optional front protection cover
(FC-SF2-H ) is available, so that the
sensing face of the sensor can be
protected in an adverse environment.
Solid aluminum case
All models have a solid aluminum case
with a thickness of 3 mm
0.118 in.
This
case is much stronger than previous
cases, so that the sensors can be
used with even greater confidence.
Mounting bracket enables easy beam alignment
The beam alignment is easy since
angle adjustment is possible with the
sensor mounting bracket (MS-SF2-1).
