SICK Introduces
World’s Most
Advanced
Hazardous-Area
Safety Light
Curtains
B
y designing an
explosion-proof
enclosure for
its leading light
curtain technology to ATEX
and UL Listed hazardous
area standards, SICK is
offering unprecedented
safety protection for
high risk flammable gas,
vapour and dusty industrial
environments.
The deTec4 Core Ex, C4000
Select Ex and C4000
Advanced Ex light curtains
are all-in-one pre-assembled
safety devices suitable for
a wide range of hazardous
environments from
pharmaceutical, chemical
and paint manufacture to
food processing and storage,
to gas and coal industries.
“This is the first time a
true fit-and-forget safety
light curtain solution
has been available for
ATEX and UL designated
hazardous areas,” points out
Martin Kidman SICK (UK)
machinery safety specialist.
“There’s no assembly
needed as the light curtain
and enclosure have already
been tested as a single
unit and verified ready for
use; the only one to have
achieved UL Classified
and Listed status so offers
complete peace of mind.
“As well as being an all-inone solution, downtime is
reduced and therefore all
the dangers of starting and
stopping critical processes
to install safety light
curtains to guard dangerous
machinery and protect
personnel are eliminated.
The range of fields and
enclosure sizes means all
sorts of equipment can be
easily protected.”
The deTec4 Core Ex, C4000
Select Ex and C4000
Advanced Ex safety light
curtain models offer a range
of protective field heights
and can be combined to
create ten different variants
within the rugged aluminium
IP66 explosion-proof
enclosure. Highly-visible
LED status indicators ensure
rapid troubleshooting.
“This is the first time
a true fit-and-forget
safety light curtain
solution has been
available for ATEX
and UL designated
hazardous areas”
Available in three different
lengths, the enclosures can
accommodate a number
of light curtains allowing
protective field heights of
600mm, 900mm, 1200mm
and even 1500mm (only
with deTec4 Core). With
a resolution of 30 mm a
scanning range of up to 16m
can be achieved (depending
on the model).
Both enclosures and light
curtains are maintenance
free and have a number
of features to aid quick
installation. The enclosures
are supplied fully assembled
and the light curtains
are pre-wired into the
enclosures to certified
standards. Quick alignment
mounting brackets enable
rapid set-up and the
optional laser alignment tool
can make installation even
easier. Removable handles
are included with the
enclosure for easy handling
and positioning by installers.
The explosion proof
enclosures for safety light
curtains are available
separately (Transmitter/
Receiver) or as a pair and
are supplied pre-wired
and assembled so that
specialist installation is
not required. They are
designed and approved for
use in hazardous locations
according to ATEX for gas:
