This prevents the sensing surfaces from
being damaged if the workpieces hit the

Light curtain is protected to prevent problems
Protection bar protects the sensing
surfaces from impacts from objects sensed
This can be used to protect the sensing surfaces even
if the light curtain is set up in harsh environments such
as places where welding spatter occurs.(optional)

Reduces losses in line
utilization rate Incorporates advanced ELCA function
The advanced ELCA function used in the SF4-A that has been widely
acclaimed by the marketplace has also been adopted into the SF4B in
order to suppress mutual interference and the effects of extraneous light.

Mutual interference is reduced without
need for interference prevention lines
The light curtain is equipped with the ELCA
(Extraneous Light Check & Avoid) function
which has already gained strong approval in
the marketplace for its powerful suppression
of mutual interference between light
curtains. Because it automatically shifts the
scan timing of the light curtain in order to
avoid interference, it is not necessary to
wire interference prevention lines between
machineries, so that the light curtains can
be positioned with much greater flexibility.

Reducing the number of malfunctions
caused by extraneous light
A double scanning method and retry processing
are two new functions exclusive to SUNX that
have been established in the workplace as
being effective in eliminating the effects of
momentary extraneous light from peripheral
equipment. The reduction in operating errors
caused by extraneous light reduces frequent
stopping of machinery and helps to prevent
losses in line operating efficiency.
The system constantly checks the light curtain for problems such as incorrect cable wiring,
disconnection and short-circuits, and also for internal circuit problems and incoming light
problems. If a problem should occur, the same output (OFF signal) as when the object was
detected is maintained in order to ensure safety, and the details of the error appear on the
digital display.
The error details can be checked at a glance without the inconvenience of the previous
method of counting the number of LED blinks, so that smooth support is possible if problems
occur at startup and during maintenance operations, even if assistance is given via
telephone.
