NPN output type
NPN open-collector transistor
Maximum sink current: 100mA
Applied voltage: 30V DC or less
Output (between output and 0V)
Residual voltage: 1V or less
(at 100mA sink current)
(at 16mA sink current)

Output operation

ON when all beams are received (OFF when one or more beams are interrupted)

Short-circuit protection

10ms or less (12ms or less when the interference prevention function is used)
Response time
Emitting indicator: Green LED

Emitter

Job indicator: Red LED (lights up, blinks or lights off when the job indicator
input is applied, selected by operation mode switch)
Operation indicator: Red LED (lights up when one or more beams are interrupted)
Stable incident beam indicator:
Job indicator: Red LED (lights up, blinks or lights off when the job indicator

Receiver

input is applied, selected by operation mode switch)
When an excess current flows through the output, the stable
incident beam indicator and the operation indicator on the
receiver blink simultaneously due to the operation of the short-
circuit protection circuit.

Make sure to carry out the wiring in the power supply off condition.

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 product, connect the frame ground
(F.G.) terminal of the equipment to an actual ground.
Do not use during the initial transient time (500ms approx.) after the
power supply is switched on.
Extension up to total 25m is possible, for both emitter and receiver, with
2
0.2mm , or more, cable. 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 sensor does not come in direct contact with water, oil,
grease, or organic solvents, such as, thinner, etc.
Do not use in an environment containing inflammable or explosive gas.
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 with their cable ends on
the same side. If they are set upside down, the sensor will not work correctly.

Thank you very much for using SUNX sensors. Please read this Instruction
Manual carefully and thoroughly for the correct and optimum use of this
sensor. Kindly keep this manual in a convenient place for quick reference.
This product is not a safety sensor. Its use is not intended or
designed to protect life and prevent body injury or property
damage from dangerous parts of machinery. It is a normal
object detection sensor.
This sensor is not for press machine safeguard. Do not use this
sensor for any press machine. For area sensors conforming to
safety standards, please contact our office.
Use M4 screws with washers and M4 nuts. The
28
tightening torque should be 0.5N . m or less.
NA2-N28
During mounting, do not apply any bending or
NA2-N28-PN
twisting force to the sensor. (Please arrange the
540mm
screws and nuts separately.)
Sensor mounting brackets (MS-NA2-1, MS-NA1-1)
are also available.

Notes: 1) Input (pink) is the job indicator input when No. 4 of the operation mode switch on the
emitter is set to the OFF side, and it is the test input when the switch is set to the ON side.
2) In order to use the job indicator as a large operation indicator, connect the input
(pink) of the emitter to the output (black) of the receiver.
3)
When the test input is set, the job indicator does
not light up or blink.
