(e.g.)

When the supply voltage is 12V, the
current consumption of the NA1-5
emitter is: 0.5W÷12V=0.042A=42mA

The sensing range gives the mounting distance
between the emitter and the receiver. In case of
NA1-5(-PN), an object can be detected even if
it is 0.2m or less (0.05m or less when set to
SHORT) away, and in case of NA1-PK5(-PN), it
can be detected even if it is 0.1m or less
(0.05m or less when set to SHORT) away.
Obtain the current consumption by the following
equation.
Current consumption=Power consumption

The model No. with suffix ‘-C5’ is 5m cable length type. (only the long sensing range: NPN output type)
Model No.: NA1-5-C5
The model No. with suffix ‘-J’ is pigtailed type. (cable length: 0.3m)
(e.g.) NA1-5-J
For the cable connected with the pigtailed type, use the connection cable CN-24-C2 (cable length: 2m) (optional)
or CN-24-C5 (cable length: 5m) (optional).

Make sure to carry out the wiring and the
operation of the operation mode switches 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.
In case noise generating equipment (switching
regulator, inverter motor, etc.) is used in the vicinity
of this sensor, connect the frame ground (F.G.)
terminal of the equipment to an actual ground.
Do not run the wires together with high­voltage lines or power lines or put them in
the same raceway. This can cause mal­function due to induction.

Do not use during the initial transient time (0.5
sec.) after the power supply is switched on.
Extension up to total 100m is possible with a

0.3mm2, or more, cable.
Avoid dust, dirt, and steam.
Take care that the sensor does not come in
direct contact with water, oil, grease, or
organic solvents, such as, thinner, etc.
Take care that the sensor is not directly
exposed to fluorescent light from a rapid­starter lamp or a high frequency lighting
device, as it may affect the sensing
performance.
The emitter and the receiver must face each
other correctly. If one of them is set upside
down, the sensor does not work.
This sensor is suitable for indoor use only.

CAUTIONS

Use M4 screws with washers, and M4 nuts.
The tightening torque should be 0.5N·m or less.

Optional sensor mounting brackets
(MS-NA1-1, MS-NA2-1) are also available.

MOUNTING

M4 screws with washers

M4 nuts

Please arrange the screws and nuts
separately.

SELECTION OF OPERATION

Selection of output operation

The output operation mode is selected by the
operation mode switch on the receiver.

Make sure to set the switches in the power
supply off condition.
The operation mode does not change even if
the setting is changed in the power supply on
condition.

BEAM AXIS ALIGNMENT

Note:

The stable incident beam indicator (green) lights
up when all the five light beams are stably
received by the receiver.

Place the emitter and the receiver face to
face along a straight line.
After the cable has 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.
