Make sure to carry out the wiring and operation
of the selection switch in the power supply off
condition.
Take care that wrong wiring may damage the
sensor.
Verify that the supply voltage variation is within
the rating.
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 during the initial transient time (0.5
sec.) after the power supply is switched on.
In case noise generating equipment (switching
regulator, inverter motor, etc.) is used in the vicinity
of the sensor, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
Extension up to total 100m is possible with
0.3mm2, or more, cable for both emitter and
receiver. However, in order to reduce noise,
make the wiring as short as possible.
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 is not directly exposed to
fluorescent light from a rapid-starter lamp or a high
frequency lighting device, as it may affect the
sensing performance.
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.
Make sure to use an isolation transformer for the
DC power supply. If an auto-transformer (single
winding transformer) is used, this product or the
power supply may get damaged.
In case a surge is generated in the used power
supply, connect a surge absorber to the supply
and absorb the surge.
The emitter and the receiver must face each other
correctly. If they are set upside down, the sensor
does not work.
In order to turn the switches, a 'minus' screwdriver
is required. (The blade should be 2.5 0.6mm or
less)
This sensor is suitable for indoor use only.
INSTRUCTION MANUAL
Use M4 screws with washers and M4 nuts. The
tightening torque should be 0.5N·m or less.
The sensor protection bracket (MS-NA3-3)
(optional) is also available.
Insert the sensor protection
bracket (MS-NA3-3) from
upwards of the sensor body,
and match the position of the
mounting holes of the sensor
body and the sensor protec-
tion bracket (MS-NA3-3).
Mount with the M4 screws
with washers and the M4 nuts
enclosed with the sensor
protection bracket (MS-NA3-3).
The tightening torque should
be 0.5N·m or less.

3)
For sensing devices to be used as safety devices for press machines or for personnel protection,
use products which meet standards, such as OSHA, ANSI or IEC etc., for personnel protection
applicable in each region or country.
In case of using as a safety device for press machine, use a product approved by the Ministry of
Labor in Japan.
Use of this product installed to a machinery or a device as a sensing device to detect a hand or a
part of the operator’s body entering a dangerous area and stop the machinery or the device.
Installation of this product to a protection device for preventing to enter a dangerous area and
use of this as a sensing device which detectes a hand or a part of the operator’s body and
open/close the door or window.
Use of this product as a sensing device for personnel protection (including interlock).

Receiver
Place the emitter and the receiver face to face
along a straight line.
After the cables have been correctly
connected, switch the power ON.
Move the emitter in the up, down, left and right
directions, in order to determine the range of the
beam received condition with the help of the
operation indicator (red) on the receiver. Then,
set the emitter at the center of this range.
Similarly, adjust for up, down, left and right
angular movement of the emitter.
Further, perform the angular adjustment for
the receiver also.
Check that the stable incident beam indicator
(green) lights up.
Interrupt each beam channel with the actual sensing
object, and confirm that the sensor operates correctly.
Note: The stable incident beam indicator (green) lights up
when all the three beams are stably received by the
receiver.
