CAUTIONS

٨

Make sure that the power supply is off while wiring.

٨

Take care that wrong wiring may damage the sensor.

٨

Verify that the supply voltage variation is within the rating.

٨

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.

٨

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.
Do not run the wires together with high-voltage lines or power lines or put

٨

them in the same raceway. This can cause malfunction due to induction.
Extension up to total 25m is possible, for both emitter and receiver, with

٨

2

0.2mm

, or more, cable. However, in order to reduce noise, make the wiring

as short as possible.

٨

Do not use during the initial transient time (500ms) after the power supply is
switched on.
Avoid dust, dirt, and steam.

٨

Take care that the sensor does not come in direct contact with water, oil,

٨

grease, or organic solvents, such as, thinner, etc.
Do not use in an environment containing inflammable or explosive gas.

٨

Make sure to use an isolation transformer for the DC power supply. If an auto-

٨

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

٨

absorber to the supply and absorb the surge.
Take care that the sensor is not directly exposed to fluorescent light from a

٨

rapid-starter lamp or a high frequency lighting device, as it may affect the
sensing performance.
The emitter and the receiver must face each other with their cable ends on

٨

the same side. If they are set upside down, the sensor will not work correctly.

٨

This sensor is suitable for indoor use only.

IN CASE OF USING JOB INDICATOR AS
LARGE OPERATION INDICATOR

٨ The job indicators can be used as large operation indicators by setting No. 4

of the operation mode switch to the 'OFF' side and connecting the input
(pink) of the emitter to the output (black) of the receiver.

TEST INPUT (EMISSION HALT INPUT) FUNCTION

٨

The emission is stopped when No. 4 of the operation mode switch is set to the
'ON' side and the input (pink) of the emitter is made High (PNP output type: Low).
Since the output can be turned ON/OFF without the sensing object, this function is
useful for start-up inspection. If the output follows the application/withdrawal of the
test input (emission halt input), the sensor operation is normal, else it is abnormal.

When the test input (emission halt input) function is set, the job indicator

When emission is stopped during the test-run function, the emitter's emitting
indicator (green) does not light up.

INTERFERENCE PREVENTION FUNCTION

٨

By setting different emission frequencies, two units of NA2-N can be mounted
close together, as shown in the figure below. The emission frequency can be
checked by the number of LEDs lighting up in the emitting indicator on the emitter.

to face along a straight line.

ԙ

After the cables have been correctly
connected, switch the power ON.

Ԛ

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 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.

ԛ

Further, perform the angular adjustment for the receiver also.

Ԝ

Check that the stable incident beam indicator (green) lights up.

ԝ

Interrupt each beam channel with the actual sensing object, and confirm that

Ԟ

the sensor operates correctly.

Note: The stable incident beam indicator (green) lights up when all the light beams are

stably received.
