◾
The length of the main unit equals
the protective height so that instal-
lation is possible in places where
space is limited. No dead zone oc-
curs at the joints between light cur-
tains when light curtains are con-
nected in series.
◾
◾
A fast response time of 14ms has been achieved regardless of
the number of beam channels, the beam axis pitches and the
number of units connected in series. This reduces calculation
work required for the safety distances.
◾
The light curtain is equipped
with a muting control func-
tion that causes the line to stop
only when a human body pass-
es through the light curtain, and
does not stop the line when a
workpiece passes through.

◾
The light curtain has a built-in external device monitoring func-
tion (such as for fused relay monitoring) and an interlock func-
tion. The safety circuit is constructed so that a separate safe-
ty relay unit is not needed, and the control board is also more
compact, both of which contribute to lower costs.
◾
The advanced ELCA function used in the SF4-A that has been
widely acclaimed in the marketplace has also been adopted
into the SF4B in order to suppress mutual interference. In addi-
tion, the unique double scanning method and retry processing
greatly reduce malfunctions due to extraneous light.
◾
If an error occurs, details of the error appear on the digital dis-
play so that maintenance can be carried out more quickly.
◾
The SF4B series combines PNP transistor output and NPN
transistor output in a single model. Overseas equipment that
uses PNP, replacement with NPN sensors, factories that are
positively grounded, and transfer of equipment overseas are all
situations where the control circuits for a single model are suit-
able for use worldwide.
