• When placing the sensor head horizontally or vertically, the
reflector must also be positioned horizontally or vertically as
shown in Fig. 1 below.
If the sensor head is placed horizontally or vertically but the
reflector is leaned as shown in Fig. 2 below, the reflection
amount will decrease, which may cause unstable detection.

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

• 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 clean of dust, dirt, water, oil, grease, etc.
• Do not apply any excessive force to
LS-MR1
.
Such force may cause damage.
2
After mounting, check that
LS-MR1
is properly fixed to
the sensor head.
Removing method
1
Insert a screwdriver into the fixing slot located at the top of
sensor head.
2
Tilt the screwdriver inserted in Step
1
to remove
LS-MR1
.
Mounting method
1
The size of upper fixing
hook of
LS-MR1
is not
same as the lower fixing
hook. After identifying
the upper and lower
fixing hooks, insert
LS-MR1
upper fixing hook into the fixing slot at the top of
sensor head and then insert
LS-MR1
lower fixing hook into
the fixing slot at the bottom of sensor head.

Others
• Do not use during the initial transient time (0.5 sec. approx.)
after the power supply is switched on.
• Because the sensitivity is higher in U-LG mode than in other
modes, it can be more easily affected by extraneous noise.
Check the operating environment before use.
• These sensors are only for indoor use.
• Avoid dust, dirt, and steam.
• Take care that the product does not come in direct contact
with water, oil, grease, or organic solvents, such as, thinner,
etc.
• This sensor cannot be used in an environment containing
inflammable or explosive gasses.
• Never disassemble or modify the sensor.
• Make sure that the power supply is off while wiring.
• Verify that the supply voltage variation is within the rating.
• Take care that if a voltage exceeding the rated range is
applied, or if an AC power supply is directly connected, the
sensor may get burnt or damaged.
• Take care that short-circuit or wrong wiring of the load may
burn or damage the sensor.
• 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.
• Ensure that an isolation transformer is utilized for the DC
power supply. If an auto transformer is utilized, the main
amplifier or power supply may be damaged.
• Make sure to use the optional quick-connection cable for
the connection of the amplifier [connector type
LS-401
(
P
) /
LS-403
]. Extension up to total 100 m
328.084 ft
is possible
with 0.3 mm
2
, or more,cable. However, in order to reduce
noise, make the wiring as short as possible.
Amplifier
Mounting
<How to mount the amplifier>
1
Fit the rear part of the mounting
section of the amplifier on a 35 mm
1.378 in
width DIN rail.
2
Press down the rear part of the
mounting section of the unit on the
35 mm
1.378 in
width DIN rail and
fit the front part of the mounting
section to the DIN rail.
<How to remove the amplifier>
1
Push the amplifier forward.
2
Lift up the front part of the amplifier
to remove it.
Note: Be careful. If the front part is lifted without
pushing the amplifier forward, the hook on
the rear portion of the mounting section is
likely to break.
<How to mount the sensor head>
1
Insert the sensor head connector
into the inlet until it clicks.
2
Fit the cover to the connector.
