For each type
①
②
Laser emission indicator LED
The LED lights up during laser emission or just before its
emission. To indicate an alarm condition, the LED on the sen-
sor head blinks.
③
Measuring range indicator LED
Blinks when a target is within the measurable range. Lights
up when a target is around the measurement center. How-
ever, it may light up or blink even with a significant error in
the measuring range when the alarm is enabled.
④
Alarm LED
Lights up when measurement is not possible (not enough
light [DARK] or too much light [BRIGHT]).
⑤
Zero-point adjusting potentiometer
Adjusts the zero-point position to within a
±
10% of F.S.
Use to make minute adjustment after installing the sensor.
⑥
SPEED 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 10Hz mode.
⑦
GAIN selection switch
Under normal conditions, set to AUTO. During edge detec-
tion and other applications where you want to cut out the low
light level areas, set to LOW.

Procedure for setting the sensor head
While watching the measuring range indicator LED,
set the sensor head so that the distance to the sub-
ject body is within the measuring range.
It may light up or blink even with a significant error in
the measuring range when the alarm is enabled.

Be careful of the sensor head's orientation during mounting. When the subject body moves as shown below, er-
rors will develop depending on the orientation of the sensor head. In order to minimize these errors, be sure to
mount the sensor head in the correct orientation.
・
Confirm the mutual interference area when using sensors side
by side.

Mounting the sensor head
Using two mounting holes, firmly mount the sensor head so that the sensor head's front surface is parallel to
the target. Do not tighten the installation screws to a torque over 2N
・
m
.
Glass is used at the sensor head's light emitting and light receiving surfaces and, therefore, never subject it to impacts of any kind. Al-
so, be very careful not to allow oils, finger prints, or other substances that may refract the light, to get on the glass during mounting.
If light reflected off the target is then reflected off nearby objects or walls and then received by the sensor head,
the sensor head reading will be adversely affected. To prevent this, either further separate the sensor head or
apply a black delustering paint to prevent the unwanted reflection of light.
●
・
Mounting the controller
When mounting more than one controllers in a row, maintain at least 10m between each unit. Also, when
mounting the controller inside control panels or areas where the air is not properly ventilated, the controller will
cause the ambient temperature to rise. In these cases, ensure cooling facilities.

Wiring
Perform all wiring by faithfully following the input and output circuit explanations
and documents that came with the instrument. Also, to protect the inner circui-
try, arrange the lead wire that is not interconnected in a way so that it does not
come into contact with other lead wires.
When mounting or removing a connector, always first turn off the controller and
then begin operations.
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 connector side and then remove the connector.
After removing a connector, do not touch the terminals located inside.
R20mm or more

・
・
Cable
When the sensor head and controller are fixed and cables connected, do
not subject the cables to a pull of more than 29.4N. Have no bends in the
cables with a radius of less than 20mm. Also, do not bend a sensor head's
cable near where the cable is attached to the sensor head.
When the sensor head is to be moved while in use, do not have it so that
the sensor head's cable becomes bent. If the location is such that it cannot
be helped, we recommend purchasing the appropriate length extension
cable. (

Insulation resistance and voltage withstandability
Do not perform insulation resistance or withstand voltage tests between the connector's metal portion and input / outputs.

Noise precautions
The connector's metal portion is internally connected to the analog output GND. In order to prevent affects from
noise or damage to the internal circuits, be sure
Ground the metal case of the sensor head to the frame ground (F.G.) of an equipment.
to insulate the metal portion with electrical tape or other means.
Mount the unit as far away as possible from high voltage lines, power lines, or devices that generate large switch-
ing surges.
Separate the sensor head cable wiring, high voltage circuit, and power circuit.
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.

Operating environment
Use in an ambient temperature between 0 to +50
℃
. Store in a location where the temperature stays between
-20 to +70
℃
.
Use in an ambient humidity between 35 to 85% RH. Avoid use in locations with drastic humidity changes which
cause condensation.
Use in locations where the illuminance from incandescent lamps received at the light receiving surface is below
2,500 lx (
ANR11
□ and
ANR1226
), or below 3,000lx (
ANR1250
,
ANR1251
,
ANR1282
,
ANR1215
).
Also, locate the unit so that sunlight, does not directly hit the beam-receiving part.
When exceptional accuracy is required, mount a shielding plate or other type of shading mechanism.
The power supply voltage should be between 85 to 110% of the rated voltage.
Since the internal circuits may become damaged if an external surge voltage exceeds 500V [
±
(1.2
×
50)
μ
s
unipolar full-wave voltage], always use a surge absorber or surge absorbing element.
Keep the sensor head beam-emitting part and beam-receiving part surface clean and free of moisture, oil, fin-
ger 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.
Although the sensor head is of water proof construction, it does not mean that measurements can be taken un-
derwater or in the rain. Moreover, the connectors are not watertight.
Do not use the unit in locations with flammable or corrosive gases, locations with excessive dust, locations
splashed by water, or locations subjected to vibrations or excessive shocks.
Since the controller contains molded resins, do not use in environments that contain, or where contact with,
benzene, thinners, alcohols and other organic solvents; and ammonia, caustic sodas, and other alkaline sub-
stances is possible.

Warm-up time
Allow at least 30 minutes, after turning on the unit, for the unit to properly warm up.

Power supply
Select a power supply with a ripple voltage below 0.5V (P-P) and a current capacity above 0.3A.
In order to avoid high-frequency noises when using a commercially available switching regulator, be sure to
ground the frame ground (F.G.) terminal.
When using a power supply that uses a transformer, be sure to use an insulated transformer. When using an
autotransformer (single-wound transformer), it is possible to damage this unit or the power supply.
Do not turn the power on again within 10 sec.after turning the power off.
