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 safety 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.
WARNING
2) Installation of this product to a protection device for preventing to enter a dangerous area and use of this as a sensing device
which detects 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 laws and
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 machines, 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 NPN output
type)
Model No.: NA1-11-C5
The model No. with suffix 'P' shown on the product affixed to the thru-beam
type sensor is the emitter, 'D' shown on the label is the receiver.
Thru-beam type sensor emitter: NA1-11P
Thru-beam type sensor receiver: NA1-11D
2) The sensing range gives the mounting distance between the emitter and
the receiver. An object can be detected even if it is 0.17m, or less, away.
3) Although this product can detect slim objects by using the cross-beam
scanning system, the size of the slim object which can be stably detected
differs with the setting distance. When this sensor is used to detect slim
objects, make sure to confirm stable detection using the actual objects.

CAUTIONS

This product has been developed / produced for industrial use only.
Make sure that the power supply is off while wiring or the
operation of the operation mode switch.
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 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 them in the same raceway. This can cause
malfunction due to induction.
Extension up to total 100m is possible, for both emitter and
2
receiver, with 0.3mm , or more, cable. However, in order to
reduce noise, make the wiring as short as possible.
Do not use during the initial transient time (0.5 sec.) after the
power supply is switched on.
Avoid dust, dirt, and steam.
Take care that the sensor does not come in contact with water,
oil, grease, organic solvents, such as, thinner etc., or strong acid,
and alkaline.
Since the cable end is not waterproof, do not use the sensor in
the application where water may seep in from the cable end.
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 with their cable ends on
the same side. If they are set upside down, the sensor will not work correctly.
This sensor is suitable for indoor use only.
Although this product can detect slim objects by using the cross-
beam scanning system, the size of the slim object which can be
stably detected differs with the setting distance. Hence, when the
product is used to detect slim objects, make sure to confirm
stable detection using the actual objects.
In case of this sensor, light from the emitter spreads above and
below the sensor. Hence, take care that if there is a reflective
object above or below the product it will affect the sensing.
