Sunx NA1-5 Instruction Manual

INSTRUCTION MANUAL
Ultra-slim Body Area Sensor
NA1-5
Series
If this product is used as a sensing device for personnel protection, serious body injury or
death could result.
Never use this product as a sensing device with any press machine, shearing machine, roll grinding
machine, forming machine, vulcanizer, or robot etc. for protection of a hand or a part of the body.
This product does not include a self-checking circuit for safety functions necessary to allow its use
as a sefety device. Thus, a system failure or malfunction can result in either an energized or a
de-energized output condition.
When this product is used as a sensing device in the following applications and if a problem relating to
'law' or 'product liability' occurs, SUNX shall not be liable for the failure and for the damage or less.
1) 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.
2) Installation of this product to a protection device for preventing to enter a dangerous area and
WARNING
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.
3) Use of this product as a sensing device for personnel protection (including interlock).
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.

Notes: 1) 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).
The sensing range gives the mounting distance
2)
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.
3) Obtain the current consumption by the following
equation.
Current consumption=Power consumption
÷Supply voltage
(e.g.) When the supply voltage is 12V, the
current consumption of the NA1-5
emitter is: 0.5W÷12V=0.042A=42mA

CAUTIONS

2
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 high-
voltage lines or power lines or put them in
the same raceway. This can cause mal-
function due to induction.
Thank you very much for using SUNX products.
Please read this Instruction Manual carefully
and thoroughly for the correct and optimum use
of this product. Kindly keep this manual in a
convenient place for quick reference.

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
0.3mm
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 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 correctly. If one of them is set upside
down, the sensor does not work.
This sensor is suitable for indoor use only.
