Built-in muting control circuit. Light curtain and emergency stops can
be controlled independently to achieve partial equipment stoppages.
Building of muting control circuits is easy
The method used to build the safety circuit is selectable
When the SF4B series of light curtains is used, the muting control circuit can be built at low cost. The newly-released SF-C14EX application
expansion unit allows the light curtain, muting sensors and muting indicators to be connected together directly, so that muting control circuits
can be built very easily.

Three safety circuit systems packaged into a single unit!
Three safety circuit systems 1 Light curtain output circuit, 2 Muting control circuit, and
3 Emergency stop circuit are packaged into a single unit. Functions that require multiple
safety relay units and muting control units can be concentrated into a single unit, which
results in large space savings, less wiring and less installation work.

(Including light curtain)
Avoids the response delays that occur when
using more than one safety relay unit, and
greatly reduces the light curtain safety
distance and improves ease of working.
Safety circuit: Linked to light curtain beam received / interrupted status (partial stop)
● When the light curtain is interrupted (when an workpiece enters
or a person intrudes), this circuit switches off (open) the safety
output and stops the turntable.
● ● If an workpiece enters when the turntable has stopped normally,
(muting conditions are achieved), this circuit allows the robot to
operate.
If an workpiece enters while the turntable is turning (muting
conditions are not achieved), this circuit switches off (open) the
safety output and stops the robot.
● When the emergency stop button is pressed, this circuit switches
off (open) the safety output and stops all equipment (turntable
and robot).

Motors that use muting control and those that
do not use it can be controlled independently!
Controls the motors that use muting control (robots) and
the motors that do not use muting control (turntables) with
a single unit.
When the workpiece comes in, the turntable can be stopped
and the robot can keep operating condition, to protect the
safety of the operator and to maintain productivity.
SF-C14EX controls three safety
output systems using only a single unit!
