Fast and easy installation
Resolution: 25 mm (1.01 in.)
Range: 7 m (23 ft.)
Protected heights: 185 to 2065 mm (7.28 to 81.26 in.)
Very compact size: 30 x 30 mm (1.18 x 1.18 in.)
Cascaded designs possible – 3 segments
Simple muting
Cross-talk prevention
Description
In addition to the simple functions inherited from the EASY type, such as global support, easy-to-view indicators, the BASIC type
includes series connection and simple muting functions . This enables the BASIC type to satisfy installations that require multiple safety
light curtains.
Up to three sets connected in a series
It is possible to con-
nect up to three sets of
safety light curtains in se-
ries. These sensors can
be placed in a U-shaped
or L-shaped pattern with
a single power line, thus
requiring less wiring.

Connection
Functions inherited from the EASY type
Simple functions such as universal power voltage specifica-
tion, easy-to-view diagnostics, a fixed response time have been
inherited from the EASY type, As a result, expect reduced
work-hours at each stage of use, from design and installation to
operation.
Global
Support
Easy-to-View
Diagnostics
Instant visibility of process trouble during muting
The BASIC type includes a muting function which temporar-
ily disables the safety light curtain when a workpiece passes
through. In the event of
any trouble occur-
ring, the error can be
instantly recognized
from the pattern of the
LED indicators, allow-
ing for a fast solution.

*1. Do not use the Support Software and Setting Console for F3SJ-A.
Operation cannot be guaranteed.
*2. Use of the Spatter Protection Cover causes a 10% maximum sensing
distance attenuation.
*3. The load inductance is the maximum value when the safety output
frequently repeats ON and OFF. When you use the safety output at 4 Hz
or less, the usable load inductance becomes larger.
*4. These values must be taken into consideration when connecting
elements including a capacitive load such as capacitor.
*5. The Vs indicates a voltage value in your environment.
*7. Mounting brackets are sold separately.
