SICK Launches Hygienic Stainless-Steel
Safety Light Curtain
W
ith a hygienic stainless-steel
housing exclusively de-
veloped to meet stringent
pharmaceutical industry requirements,
the SICK TWINOX4 safety light curtain
is resistant to aggressive cleaning and
decontamination regimes. The TWI-
NOX4 is a Type 4 device (IEC 61496-1)
with 14mm beam resolution and can
be used in safety applications requir-
ing PLe (EN ISO 13849) and SIL3 (EN
62061).
The SICK TWINOX4 safety light curtain
protects operating personnel when
interventions are required in the
hazardous areas around machines
that are subject to stringent hygiene
requirements. It is ideal for use in
24
Restricted Access Barrier System areas
such as primary packing and filling
stations.
Rugged, resistant to harsh cleaning
media and designed without edges or
gaps, the TWINOX’s elegant, 20 mm x
40 mm cross-section dimensions make
it particularly suitable for integration in
pharmaceutical machinery when space
is limited.
“The SICK TWINOX4 offers
pharmaceutical manufacturers the twin
protection of hygienic design together
with technology-leading machinery
safety,” explains Dr Martin Kidman,
SICK’s UK machinery safety product
manager.
“The TWINOX therefore offers a more
flexible solution to protect hazardous
areas on pharmaceutical production
lines and clean room access points.
Aggressive cleaning agents and
disinfectants, such as hydrogen
peroxide, require media-resistant
materials. The SICK TWINOX4 offers
the robust reassurance of maximum
production availability and operating
longevity.”
The SICK TWINOX4’s has an innovative
bracket concept and LED status
indicators for rapid mounting and easy
alignment, maximising machine and
system availability.
