Do not stare into the laser beam directly, install at
eye-level of the people around, nor expose the beam to
the human body intentionally.
Use the exclusive amplifier unit to connect the product.
Not doing so may result in an accident or product damage.
Wiring or disconnecting with the power ON is danger.
Never fail to turn OFF the power supply.
This product cannot be used as a safety device to
protect human body.
Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
Precautions in using WSE130L
When using WSE130L-32/34 or WSE130L-52/54 for length measurement, follow
the instructions below.
Emitter is applied to gray cable and Receiver is applied to black one.
Install the sensor so that the sensor of flood beam is positioned in the center of
the light receiving part. (Install so that the indication value of amplifier unit is
Install the flooding/receiving device in the same direction.
Refer to each label or indicator light as a standard.
P41F Reflector (WL130L-32)
Instruction for use
1. When cleaning, blow off or lightly wipe with a soft cloth.
Do not use thinner, benzene or kerosene.
2. Avoid strong push of the reflecting surface or direct impact.
Doing so may result in damaging the prism and deteriorating the performance.
3. Avoid using outside or under the environment where oil or water scatters.
Refer to the figure below and use in the correct direction.
Improper installation may cause malfunction.

Meanings of Safety Symbols
Indicates a possible hazard that may result in death,
serious injury, or serious property damage if the pro-
duct is used without observing the stated instructions.
Indicates a possible hazard that may result in
personal injury or property damage if the product is
used without observing the stated instructions.

not use the product under flammable, explosive gas or
Use of controls or adjustments or performance of pro-
cedures other than those specified herein may result
in hazardous radiation exposure.
The light source of this product applies the visible light
Do not disassemble or modify the product since it is
not designed to automatically stop the laser emission
when open. Disassembling or modifying at customer's
end may cause personal injury, fire or electric shock.
Installing in the following places may result in malfunction:
1. A dusty or steamy place
2. A place generating corrosive gas
3. A place directly receiving scattering water or oil
4. A place suffered from heavy vibration or impact
Do not use the sensor outside nor expose the detection
surface directly to ambient light (laser light, incandes-
cent light and sunlight).
Do not use the sensor in transient state after power on
(approx. 100 ms).
The sensor performance may depend on the individual

Laser emission warning light
Confirmation of laser emission is available with the laser emission warning light.
It starts lighting after turning the power on and keeps lighting while the laser is
being radiated. It is also possible to confirm with the exclusive amplifier unit.
Laser radiation warning light (Green)
This product is classified as a Class 2 (II) Laser Product by JIS C6802 / IEC / FDA
Laser Safety Standard as this radiates the visible laser beam. The warning label and
the description label in English are attached on the side face of the sensor head
indicating the CLASS 2/Class II.
*The emitters WS130L-34 and WS130L-54 of WSE130L-32/34 and WSE130L-52/54 are rated
as Class II by the FDA standard (when exporting to the US). However, the class 1 is applied for the
When exporting this machine to the US, the US laser control, FDA (Food and Drug
Administration) is applied. This product has been already reported to CDRH (Center
