Sigmaguard Specialist LED Indicators
Any Symbol, Any Character, Any Standard Colour
Specialist Signals for Specialist
Applications
Standard or custom specialist indicators
assembled from the same high-reliability
subassemblies used for our mainline
signals.
Signals can use a custom LED layout, or the
inside front cover can be treated to display
specific symbols or characters in any of the
standard signal colours.
Exceptional Reliability
Benefits
Custom-designed characters and symbols
Benefits
140, 200 and 300 mm circular modules
Single- and multi-aspect cases suit standard
mounts
Long service life with high reliability LEDs and
power supplies
High intensity
Wide viewing angle
Multiple LEDs and parallel circuitry
combined with the exceptional reliability of
LED technology leads to lower
maintenance costs and fewer train delays
than incandescent lamps — essential for
today’s rail industry.
Any Housing, Any Mounting
Choose single- or multi-aspect housings,
with optional hoods and background, to
install these modules on top-of-post or
front-of-post mounts.
Low power consumption and wide voltage range
Available in white, red, yellow and green
High-strength lightweight polycarbonate module
5-year standard warranty

Description
Siemens 140, 200 and 300 mm LED
indicator modules are high-safety, lowmaintenance solutions for specialist signal
or indicator displays.
• LED layout types use a custom
display printed circuit board to
position LEDs for the character or
symbol. Suits medium to large
volumes and displays a slightly
clearer character.
• Masked layout types use a speciallytreated masked front cover that
allows a standard circular LED array
to be masked to the required
character. Quick and simple to
produce for small and medium
volumes. There are some limitations
on character or symbol shape.

• ensures constant brightness over a
wide voltage range — no need to set
the voltage at the indicator during
installation
• uses about half the power of
incandescent signals, allowing the
use of smaller power supplies

Reliability
These indicators don’t rely on a single
light source for safety-critical signalling
applications. Multiple LEDs in the signal
elements are in an interconnected
matrix.

Indicator
Just a few of the possible configurations:
Not only is each LED over 1000 times
more reliable than an incandescent
lamp, the light output will not reduce by
more than 5% if one LED fails.
Siemens warranties each LED indicator
for 5 years.
Construction
High-strength polycarbonate LED
module enclosure.
Housings
Modules fit in standard style U2L
(140 mm) housings and style L2
