Recognizes extraneous light and prevents malfunctions
Mutual interference is reduced without
the need for interference prevention lines
Spatter protection for the sensing surface
The spatter protection hood type, now available, protects the sensing surface from
welding machine spatter. Moreover, a front protection cover that can be installed
within the sensor casing is also available, completely preventing spatter from
adhering to the sensing surface.
In addition, even though sensed objects may contact the sensor, the sensing
surface will be protected. The ELCA function implements all possible measures to
prevent malfunctions caused by spatter.
Front protection cover protects the sensing surface
In the event that the SF2-A series is
installed in a harsh environment, the
use of the front protection cover
(FC-SF4A-H
, optional) will protect
the sensing surface from damage.
Mounting bracket enables easy beam-axis alignment
The beam-axis alignment is easy since
angle adjustment is possible with the
enclosed rear mounting bracket
(MS-SF2N-1).
Alternatively, the side mounting
bracket (MS-SF2N-3) is also available
as an option.
Alignment of beam axes can be accurately performed prior to power-up
By using the SF-LAT-2N laser
alignment tool, you can quickly and
easily align beam axes. The laser
beam spot is easy to see, even when
light curtain units are installed far
apart. In addition, as the SF-LAT-2N
laser alignment tool is battery-
operated, beam axes can be aligned
before powering up the light curtain
itself.

Reducing mutual

High immunity to
interference from
extraneous light

This function allows the sensor to recognize and reject interference from
instantaneous extraneous light emitted from peripheral equipment, thus
preventing malfunctions caused by a variety of sources, including: other sensor
beams in the vicinity of the operating sensor, beam spatter, AGV and rotating light
sources.
By reducing the number of malfunctions caused by extraneous light, detection
operations will be interrupted less frequently, resulting in substantial improvements
in work efficiency.
The ELCA (Extraneous Light Check &
Avoid) function enhances the mutual
interference prevention function.
ELCA decreases interference from
extraneous light having a similar
frequency as the light used by the
SF2-A series, thereby also minimizing
mutual interference among nearby
SF2-A series sensor units.
