Solid State LED Annunciators
AML45/59 Series
FEATURES
Messages are backlighted with LED’s
for long, reliable operating life.
Reduces service and maintenance
costs.
Low voltage and current (without
inrush), enables direct drive with
integrated circuits. Reduces cost of
interface components (and
installation), and power supply.
Low operating temperature allows
high-density, continuous operation.
Minimal heat build-up.
Inherently rugged. Resists effects of
shock and vibration (no filaments to
break).
High density message display.
Illuminates up to four legend sectors
in color, in a 0.8
×
1.2 inch area.
Dead front hides legends until
illuminated. Non-glare display with no
flickering.
UL recognized.
Manuals
AML45/59 solid state LED annunciators
are a state-of-the-art advancement over
traditional back-lighted legend displays
which utilize incandescent lamps. The
LED light source imparts the benefits of
solid state long-life and reliability, with low
power requirements. Operating life is
measured by years, instead of hours.
The AML45 housing has two high effi-
ciency LED’s which illuminate color filters
and film legends located in the snap-on
AML59 cap assembly. There is a choice of
full face one-color and split one-color or
two-color displays. Color options are red,
green, and yellow.
Film legends offer a choice of negative or
positive formats. (Note: human factors
engineers generally favor negative an-
nunciator messages, reserving the posi-
tive format for use if special attention is
necessary, such as ‘‘PAPER JAM.’’)
When unlighted, the legend is hidden
(dead front).
NEGATIVE
When illuminated, colored legend ap-
pear1001s against a black background.
NEGATIVE
POSITIVE
When illuminated, black legend appears
against a colored background.
POSITIVE
This annunciator is totally compatible
with other deivces in the MICRO SWITCH
AML Advanced Manual Line both in front
of, and behind the panel. Two of them fit in
the same space as a rectangular AML
indicators or switch. All terminals exit at
AML’s standard 1.7-inch depth for conve-
nient, single-level wiring.

AML45 LED HOUSINGS
LEDs should be specified as the same
color if a full or split screen one-color
display is desired (RR
=
red); or different
colors for a split screen two-color display
(RY
=
red/yellow). (Baffle plate inside
housing prevents light spillage from one
LED color section to the other on split
screen versions.)
LED colors should match filter colors
specified in AML59 cap assembly (see
page 40).
Spring clips on sides of the housing hold
units securely in panel. For mounting
strips of two or more units, AML61 mount-
ing hardware may be used (see page 55).
LED APPLICATION INFORMATION
Refer to page 59.
PANEL ORIENTATION
Drawing (above) indicates Side 1 and
Side 2 LED locations, with MICRO
SWITCH identifications facing UP. Con-
sider this orientation when ordering an
AML45S
housing with two different LED
AML45/59 Series
colors, such as RG (red/Side 1, green/
Side 2). Since LED’s are permanently in-
stalled, color location is specially impor-
tant to note when the device is to be termi-
nated in a printed circuit board.

SUBPANEL MOUNTING
AML61 mounting hardware may be used
for mounting strips of two or more an-
nunciators in pairs in a single cutout. This
method is most cost-effective for multi-
unit application, since it generally takes
less time to make one large hole to accept
several units than it does to make a hole
for each individual unit. Also, if the front
panel is not required for mounting sup-
port, it can be made thinner, and easier to
cut out, minimizing installed cost.
AML61 strips are factory assembled with
metal cans welded together, and mount-
ing brackets welded to the end cans. Re-
fer to page 45 for ordering information.
INSTALLATION
Each rectangular AML61 mounting can
will accommodate two annunciators, as
shown in the drawing. Panel appearance
is enhanced if a spacer .05 in./1,3 mm
thick (approx.) is installed between the
housings at the terminal end. Specify Cat-
alog Listing 30PA1-AML for a package of
10 spacers.
AML45/59 Series
Mounting centers and panel cutout di-
mensions are shown on page 64. An in-
stallation instruction sheet PK8520 is
shipped with each order.
Order AML45/59 annunciators and
AML61 mounting hardware separately.

AML59 CAP ASSEMBLIES
The cap assembly consists of: black cap,
color filter(s), and optional film legend;
furnished unassembled. It snaps onto
housing, flush with the housing bezel.
Filters, assembled with their matte finish
facing the LED’s, efficiently diffuse the
illumination. They are color-tinted to com-
plement the red, yellow, and green LED’s.
NOTE: Cap assembly should not be sub-
jected to the temperature and chemical
atmosphere associated with wave solder-
ing. These parts should be installed after
soldering and cleanup.
Catalog listings for AML59 cap assem-
blies are derived from the ordering guide
below. The ordering guide for AML45 LED
housings is on page 38.
CUSTOM LEGENDS
A 2:1 drawing in black ink is required for
satisfactory reproduction of custom film
legends. As an alternative, you may sub-
mit an office copy of a page from a ty-
pographic supplier catalog such as Char-
tpak, Letraset, and Zipatone. MICRO
SWITCH can also furnish graphic leg-
ends from the ‘‘Henry Dreyfus Symbol
Source Book.’’ (Custom legends require
a one-time start-up charge.)
