RAY-LG 35XX
Version: 1.0
Product Description
The RAY-LG is a very reliable SIL 2 certified safety
light curtain. It was developed and designed to
safeguard all types of vertically opening industrial
doors such as sectional or highspeed doors. The
system is ideal for door openings up to 10 m width
and can handle door closure speed of 1.6 m/s. The
opening speed is up to 3 m/s. The emitter and
receiver are preferably installed directly inside the
guide rail.
The RAY-LG has a selectable transistor
(NPN/PNP) or OSE output, so one system can
handle all relevant outputs. Selecting the OSE
output allows operation according to EN ISO
13849-1:2015 Cat. 2 without periodic testing of the
light curtain. This output is included in the TÜV
certification of the RAY-LG.
Functionality
The emitter and receiver edges create a grid of
infrared beams offering up to 2.5 m (8.2 ft) in
protection height.
When the infrared beams are interrupted, the
output sends a signal to the connected door
control unit. As soon as the detection area is clear
again, the output switches to indicate that the area
is "clear". The blanking system is designed to
mount directly into the guide rails. As the door
closes, the RAY-LG recognizes the door as such
and does not switch the output.
Once the door has arrived at the fully closed
position, the output signal will be switched off.

is
certified
according
to
EN ISO 13849-1:2015 and EN 12978:2009 if the
door is monitored over its full height up to 2.5 m
(8.2ft). It is designed and approved for mounting
and use in- and outside the side guides of
industrial doors and serves as E-device presence
detection
according
to
EN 12978:2009
and
EN 12453:2017.
The RAY-LG 35XX fulfills the safety level up to
