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 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.

Laser emission indicator (green)

m or less.

When placing the sensor horizontally or
vertically, the reflector must also be
positioned horizontally or vertically as

Sensor bracket
(optional)

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>

When placing the sensor horizontally or vertically, the reflector shall also be
positioned horizontally or vertically.

Good

<Fig. 2 Improper positioning>

When placing the reflector tilted even when the sensor is positioned
horizontally or vertically.

Not good

Note: The diagrams above are examples for the sensor head (LS-H91) with the reflector (RF-330).

For the sensor head (LS-H92) with the reflector (RF-230), take care of the posisioning as well.

COAXIAL RETROREFLECTIVE TYPE
(Only for LS-H91 and LS-H92)

In principle, the coaxial retroreflective type (LS-H91 and LS-H92) 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.

<Measures>

Lower the receiving light sensitivity with the M.G.S. function of the

・

amplifier.
Change the response time.

・

Make the distance between the sensor head and the sensing object

・

farther.

The receiving light intensity may change depending on the surface

●

condition of the reflector. When a threshold value is set with the applicable
amplifier LS-400 series, sufficient margin should be taken into accout.
LS-H92 is in super high sensitivity setting. Thus, the output may be unstable

●

since it can be easily affected by extraneous noise. In this case, lower the
the receiving light sensitivity with the M.G.S. function. The sensing distance
depends on the receiving light sensitivity as shown in the table below.

SPOT-SIZE ADJUSTER
(Only for LS-H21 and LS-H22)

The diffuse reflective type (LS-H21 and LS-H22) incorporates the

●

spot-size adjuster to adjust the size of spot diameter.

LENS ATTACHMENT FOR LINE REFLECTIVE
TYPE (LS-MR1) (Only for LS-H21 and LS-H22)

The lens attachment for line reflective type (LS-MR1) mounted in the

●

long sensing range line reflective type (LS-H22) is removable.
When LS-H22 is used without LS-MR1, it will provide the equivalent
performance to the long sensing range spot reflective type (LS-H21). In
addition, the optional LS-MR1 can be attached to LS-H21 to obtain the
performance equivalent to LS-H22.
Keep the lens from dust, dirt, water, oil, grease, etc.

●

Do not apply any excessive bending force

●

to LS-MR1. Such force may cause damage.

Removing method
