The Latest
Safety Light Curtain From the Press-Guarding
Experts
Wintriss has been building the Shadow light
curtains for the toughest applications for more
than 35 years. Our light curtains withstand the
rigors of the pressroom, including severe shock,
mechanical abuse, and lubricant spray. With more
than 45,000 systems installed, the Shadow has a
proven track record.

Shadow 8 Heads Connect Directly to
New WPC 1000 and WPC 2000 For press
guarding applications, up to 4 pairs of Shadow 8
heads can connect directly to the new
WPC 1000 and
WPC 2000 Wintriss Clucth Brake Controls -
with no need for a separate control box. This
reduces both the initial investment in equipment
and the cost of installation.
Connect up to Four Pairs of Heads to
One Control
Shadow 8's unique design enables you to protect
multiple sides of a machine using a single
control, one pair of cables, and up to 4 pairs
of light curtains in series. You can protect
both the front and back of your equipment as
well as provide horizontal pass-through
detection. Even a large machine can be guarded
with up to 202” of protected zone to a single
control providing an economical solution and
minimizing installation time (for either the
transmitter or receiver, the total length of the
heads and interconnect cabling cannot exceed 110
feet).
Programmable Fixed Blanking
Fixed blanking windows disable one or more beams
to allow stationary objects such as conveyors or
work tables to remain in the sensing field.
You simply place the obstruction between the
transmitter and receiver and turn the key-lock
switches on the control. Shadow 8 senses the
presence of the object and “blanks” the
obstructed beams. The Individual Beam Indicators
(IBIs) light up to indicate which beams are
blanked. When the object is removed, the system
will not allow the machine to run until the
control has been reprogrammed to “unblank” the
beams. The first or the main segment must have a
minimum of 7 to 9 consecutive beams (5.5” to 7”)
not blanked based on its height (e.g., the 12”
main segment must have 7 consecutive beams
(5.5”) not blanked) and 2 consecutive beams in
each extension must not be blanked.
Individual Beam Indicators (IBIs)
Floating Blanking Window Shadow 8 also enables you to set a
floating blanking window, one beam wide, to
allow objects smaller than 1”, such as
air-ejected parts, to pass through the light
curtain in a random pattern without interrupting
operation. This can also be useful when air or
hydraulic lines need to pass through the field.
You can use both floating and fixed blanking
simultaneously.
3rd Party Verifications
Instead of saying “designed to meet”, at
Wintriss we felt it was important to subject our
systems to the toughest third party
certifications. Shadow 8 has undergone
independent testing and certifications by
Underwriters Laboratories (NRTL/C) to CAN/CSA
22.2 No. 14 and CAN/CSA 22.2 No. 0.8 and by TÜV
to Category 4 CE/IEC 61496-1 and CE/IEC 61496-2.
Shadow 8 complies with OSHA 1910.217, ANSI
B11.1, ANSI B11.19, CSA Z142 and CSA Z432.
Helps You Comply with OSHA Lockout/Tagout
Shadow 8 light curtains can eliminate the need
to lockout/tagout during die changes. OSHA
regulation 1910.147 states that lockout is not
required when the activity is “routine and
integral to production and personnel are
protected by other guarding methods.”
Service And Support
It’s necessary to have a thorough understanding
of the various safety regulations when applying
a safety light curtain system in your
application. Both factory personnel and our
representatives keep up with these changes. At
your request we will check out your application
and make recommendations for the proper light
curtain configuration as well as any
supplemental guarding that may be required.
All of our light curtain systems carry a 2-year
warranty. If a system does go down, we have a
48-hour turnaround policy on repairs.
Shadow 8 heads are available
in lengths from 12" to 59" (extensions from 9")
