High-precision measurements with
comparative output function
Comparative output function (Intensity/displace-
ment) gives this high-precision device more ver-
satility
In addition to conventional analog output, the LM10 also comes
with ON/OFF control outputs;single (high/low outputs) or double
(high/low/go outputs) comparators. This gives the LM10 the ver-
sitility of both a photoelectric sensor and a high precision laser.
• Setting modes and types of ON/OFF control
New circuitry lowers costs.
Incorporates our own unique built-in single-
channel IC.
The LM10 uses the first single-channel IC (patent pending) ever
produced in the industry,* which reduces the dual-channel pro-
cessing requirement of conventional products to a single chan-
nel. Building the arithmetic circuits into the IC has also helped to
reduce costs. • As of November 1996.
• Measurement principle of the LM10 (optical triangulation)
Part of the light rays which come from the target object by means of dif-
fuse reflection are focused to produce a light spot on the position sens-
ing device (PSD). The location of this light spot varies depending on the
distance of the target object. By measuring the change in the location of
the light spot, the LM10 can measure the displacement of the target
object.

Use the LM10 with confidence. It
meets FDA standards for class 2 laser
safety.
Products available in two series: laser class 2
high and low power.
Development of a high-precision aspheric surface plastic lens
has made it possible to maintain both high precision and class 2
safety. The visible light spot makes it easy to see and safe to
use.
Interchangeable sensor heads
Sensor head and controller can be managed
separately.
Nine types of sensor heads and eight types of controllers can
be freely combined in 72 different ways. Unlike those of conven-
tional laser sensors, these heads and controllers are completely
interchangeable to meet any type of measuring and processing
requirements, There is no need for matched pair management
of heads and controllers.
Excellent in the following circumstances...
• When carrying out repairs
Suppose an accident on the production
line damages the sensor head.
...all you have to do is replace the
sensor head. As long as there is a
spare sensor available, the prob-
lem can be solved without stop-
ping the production line.

• When changing to a
different model.
Suppose that after purchasing the
LM10 it becomes necessary to switch
to a different model due to changes in
the object you are measuring.
...all you have to do is buy a new
sensor head. The current con-
troller need not be replaced.

Q, WLaser emission indicator LED
This LED lights during laser emission or
just before and after its emission. To
indicate an alarm condition, the LED on
the sensor head flashes.
ERange indicator LED
Flashes when the target is within the
measurable range. Stays lit when the tar-
get is near the center point distance.

ble (not enough light [DARK] or too much
light [BRIGHT])
TZero-point adjustment
potentiometer
Adjusts the zero point position to within a
±10 % F.S. Use to make minute adjust-
ments after installing the sensor.
YSPEED selection switch
The response speed can be set to one of
three settings to allow adjustment for the
target speed. When high response
speed is unnecessary, set to the 10 Hz
mode.
UGAIN selector switch
Under normal conditions, set to AUTO.
During edge detection and other applica-
tions where you want to cut out the low
light level areas, set to LOW.

2. Timing input [light blue]
While shorted to 0 V (blue), the comparison
output is disabled. When using a transistor
to establish the timing, use a transistor
with a residual output voltage of 1.5 V or
less during output.

3. Cross-talk prevention I/O
[green (input), yellow (output)]
When using two sensors, you can set the
cross-talk prevention mode by connect-
ing the input wire of each to the output
wire of the other. Be aware that this
mode may adversely affect the linear
characteristics, resolution, and response.

4. Analog displacement output
[white, shielding (GND)]
An analog voltage is output that corre-
sponds to the displacement of the target
within the measurement range. When
the output switch is at the SET position,
each comparison value setting is output.
5. Intensity output
[red, shielding (GND)]
Analog voltage (–5 V to +5 V) is output
corresponding to the amount of light
reflected from the target. If the amount of
light increases, the voltage value
becomes larger and if it decreases, the
voltage value becomes smaller.
6. Alarm output
[orange, white (COM)]
Outputs during insufficient light (DARK)
or too much light (BRIGHT).
• Single comparator type
[black, white (COM)]
• Window comparator type
[black, gray, purple, white (COM)]
Judgment result of displacement data is
output.

LOW [purple] Outputs when below the set
value’s lower limit.
IN RANGE [gray] Outputs when between the set
value’s lower and upper limits.
HIGH [black] Outputs when above the set
value’s upper limit.
Comparing operations
When displacement data is
greater than set value (far side):
FAR/LIGHT ON output is on.
When displacement data is less
than set value (near side):
NEAR/DARK ON output is on.
When intensity data is greater
than set value (near side):
FAR/LIGHT ON output is on.
When intensity data is less than
set value (far side):
NEAR/DARK ON output is on.
Note: With the single comparator type, connecting the purple
wire and blue wire changes from the analog displace-
ment output to the light amount monitoring value output.

Precautions during installation
1. Procedure for setting the sensor
1) While watching the range indicator
LED, set the sensor so that the distance
to the subject body is within the measur-
able range.
2) Be careful of the sensor’s orientation
during installation. When the subject
body moves as shown below, errors will
develop depending on the orientation of
the sensor. In order to minimize these
errors, be sure to install the sensor in the
correct orientation.
2. Installing the sensor
1) Using the two installation holes, firmly
install the sensor so that the sensor’s
front surface is parallel to the target. Do
not tighten the installation screws to a
torque over 2 N·m.
2) Glass is used at the sensor’s light
emission and light reception surfaces
and, therefore, never subject it to
impacts of any kind. Also, be very careful
not to allow oils, fingerprints, or other
substances that may refract the light, to
get on the glass during installation.
3) If light reflected off the target is then
reflected off nearby objects or walls and
then received by the sensor, the sensor
reading will be adversely affected. To
prevent this, either further separate the
sensor or apply a black delustering paint
to prevent the unwanted reflection of
light.
3. Installing the controller
1) When installing more than one con-
troller in a row, maintain at least 10 mm
between each unit. Also, when installing
the controller inside control panels or
other areas where the air is not properly
ventilated, the controller will cause the
ambient temperature to rise. In these
cases, ensure the proper cooling facili-
ties.
4. Wiring
1) Perform all wiring by faithfully follow-
ing the input and output circuit explana-
tions and documents that came with the
instrument.
2) When installing or removing a connec-
tor, always first turn off the controller and
then begin operations.
3) All connectors are of the lock-on type.
When connecting a connector, be sure to
securely insert it until it locks into place.
When removing a connector, first press
in the lock release button on the connec-
tor side and then remove the connector.
4) After removing a connector, do not
touch the terminals located inside.
5) The connector’s metal portion is inter-
nally connected to the analog output
GND. In order to prevent affects from
noise or damage to the internal circuits,
be sure to insulate the metal portion with
electrical tape or other means.
5. Cable
1) When the sensor and controller are
fixed and cables connected, do not sub-
ject the cables to a pull of more than 3
kg. Have no bends in the cables with a
radius of less than 20 mm. Also, do not
bend a sensor’s cable near where the
cable is attached to the sensor.
2) When the sensor is to be moved while
in use, do not have it so that the sensor’s
cable becomes bent. If the location is
such that it cannot be helped, we recom-
mend purchasing the appropriate length
extension cable so that bending is
unnecessary.

Precautions during operation
1. Operating environment
1) Use in an ambient temperature
between 0 °C 32 °F and 50 °C 122 °F.
Store in a location where the tempera-
ture stays between –20 °C –4 °F and
70 °C 158 °F.
2) Use in an ambient humidity between
35 % and 85 % RH. Avoid use in loca-
tions with drastic humidity changes
which cause condensation.
3) Use in a location where the illumi-
nance from incandescent lamps received
at the light receptors surface is below
2,500 lx (ANR11 series and ANR1226),
or below 3,000 lx (ANR1250, ANR1251,
ANR1282, and ANR1215). Also, locate
the unit so that sunlight, light of the same
wavelength, or other disturbing light,
does not directly hit the light receptor.
When exceptional accuracy is required,
install a shielding plate or other type of
shading mechanism.
4) The power supply voltage should be
between 85 % and 110 % of the rated
voltage.
5) Since the internal circuits may
become damaged if an external surge
voltage exceeds 500 V [±(1.2 ×50) µs
unipolar full-wave voltage], always use a
surge absorber or surge absorbing ele-
ment.
6) Keep the sensor light emitter and light
receptor surface clean and free of mois-
ture, oil, finger prints, and other light
refracting substances, and free of dust,
dirt, and other light blocking substances.
When cleaning the glass surfaces, wipe
with a soft cloth or lens cleaning paper.
7) Although the sensor is of waterproof
construction, it does not mean that mea-
surements can be taken underwater or in
the rain. Moreover, the connectors are
not watertight.
8) Do not use the unit in locations with
flammable or corrosive gases, locations
with excessive dust, locations splashed
by water, or locations subjected to vibra-
tions or excessive shocks.
9) Since the controller contains molded
resins, do not use in environments that
contain, or where contact with, benzene,
thinners, alcohols and other organic sol-
vents; and ammonia, caustic sodas, and
other alkaline substances is possible.
2. Noise precautions
1) Install the unit as far away as possible
from high voltage wires, power wires, or
devices that generate large switching
surges.
2) Separate the sensor cable wiring, high
voltage circuit, and power circuit.
3) If there is much noise on the power
supply, it will affect the analog output. In
such cases, use a noise filter or noise-
cut transformer.
3. Insulation resistance and withstand
voltage
1) Do not perform insulation resistance
or withstand voltage tests between the
connector’s metal portions and input/out-
puts.
4. Power supply
1) Select a power supply with a ripple
voltage below 0.5 V (P-P) and a current
capacity above 0.3 A.
2) In order to avoid high-frequency nois-
es when using an off-the-market switch-
ing regulator, be sure to ground the
frame ground (FG) terminal.
3) When using a power supply that uses
a transformer, be sure to use an insulat-
ed transformer. When using an auto-
transformer (single-wound transformer),
it is possible to damage this unit or the
power supply.
5. Warm-up time
1) Allow at least 30 minutes, after turning
on the unit, for the unit to properly warm
up.
Area of interference
When using more than one sensor
together, be careful of the area of inter-
ference.
