This product has been designed to meet the specifications when it is used
along with the optional exclusive amplifier. If an amplifier other than the
exclusive amplifier is used, not only the specifications may not be met, but
it may also be a cause for malfunction or break down. Hence, please
ensure to use this product along with the optional exclusive amplifier.

This product has been developed / produced for industrial use only.
Always use the sensor with the connector to be joined to the amplifier.
Make sure that the power is off while wiring to the amplifier.
In case noise generating equipment (switching regulator, inverter motor
etc.) is used in the vicinity of this product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
If power is supplied from a commercial switching regulator, ensure that
the frame ground (F.G.) terminal of the power supply is connected to an
actual ground.
Do not use the sensor during the initial transient time (0.5 sec.) just after
the power supply is switched on.
Do not run the wires together with high-voltage lines or power lines or put
them in the same raceway. This can cause malfunction due to induction.
Take care that the sensor head is not directly exposed to fluorescent
lamp from a rapid-starter lamp or a high frequency lighting device, as it
may affect the sensing performance.
The sensor head cable cannot be extended.
Make sure that stress is not applied directly to the sensor head cable
joint.
This sensor is suitable for indoor use only.
Do not allow any water, oil fingerprints, etc., which may refract light, or
dust, dirt, etc., which may block light, to stick to the emitting / receiving
surfaces of the sensor head. In case they are present, wipe them with a
clean, soft cloth or lens paper.
Do not use the sensor in vaporous, dusty or corrosive gas atmospheres.
Take care that the sensor does not come in contact with water, oil,
grease or organic solvents, such as, thinner, etc.
Make sure that the power is off while cleaning the emitting / receiving
windows of the sensor head.

Never use this product as a sensing device for personnel protection.
In case of using sensing devices for personnel protection, use
products which meet laws and standards, such as OSHA, ANSI or IEC
etc., for personnel protection applicable in each region or country.
Although this product corresponds to a Class 1 laser product, it is
dangerous to see the laser beam which has been passed through a
viewing optical system such as a lens etc. Hence, please avoid this.
Use of control or adjustment or performance of procedures
other than those specified in this instruction manual may
result in hazardous radiation expose.

●When placing the sensor horizontally or vertically, the reflector must also
be positioned horizontally or vertically as shown in Fig. 1 below. If the
sensor is placed horizontally or vertically but the mirror is tilted as shown
in Fig. 2 below, the reflection amount will decrease, which may cause
unstable detection.
<Fig. 1 Proper positioning>
Mount the reflective mirror horizontally or vertically toward LS-H□-A.
<Fig. 2 Improper positioning>
The reflective mirror must not be tilt toward the LS-H□-A.

●The diffuse reflective type (LS-H21-A) incorporates the spot-size
adjuster to adjust the size of spot diameter.
DescriptionSpot-size adjuster
Turn the spot-size adjuster clockwise or counterclockwise to adjust the
spot diameter at your desired detecting distance.
However, if the adjuster is over turned, it may be damaged.
●
In principle, the coaxial retroreflective type (LS-H91-A) may be unable to
detect a mirror object or an object which easily diffuses the receiving light
at a short sensing distance since the polarized light becomes unstable.
In this case, take the following measures.
●The receiving light intensity may change depending on the surface
condition of the reflector. When a threshold value is set with the applica-
ble amplifier LS-400 series, sufficient margin should be taken into
account.
