Sunx CX-400 Series, CX-441, CX-442-P, CX-442, CX-441-P Instruction Manual

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.

٨٨Never use this product as a sensing device for personnel protection.

In case of using sensing devices for personnel protection, use products which
meet standards, such as OSHA, ANSI or IEC etc., for personnel protection
applicable in each region or country.

WARNING

When detecting a specular object (aluminum
or copper foil, etc.) or an object having a
glossy surface or coating, please take care
that there are cases when the object may
not be detected due to a small change in
angle, wrinkles on the object surface, etc.

Do not make the sensor
detect an object in this

cause unstable operation.

Notes: 1) The model No. with suffix '-Z'㩷is M8 plug-in connecotor type.

For the M8 plug-in connector type, use the following mating cables.

CN-24A-C2 (Straight type, 4-core, cable length 2m) CN-24AL-C2 (Elbow type, 4-core, cable length 2m)

2)3)The adjustable range stands for the maximum sensing range which can be set with the distance adjuster.
The detection may be unstable depending on the mounting conditions or the sensing object to be used. In the
state that this product is mounted, be sure to check the operation with the actual sensing object to be used.

When a specular body is present below the
sensor, use the sensor by tiling it slightly
upwards to avoid wrong operation.

If a specular body is present in the
background, wrong operation may be
caused due to a small change in the angle
of the background body. In that case, install
the sensor at an inclination and confirm the
operation with the actual sensing object.
Take care that there is a non-detactable
area right in front of the sensor.

Make sure that the power supply is off while
wiring and adjusting.
Take care that wrong wiring will 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.

or more, cable. However, in

order to reduce noise, make the wiring as
short as possible.
Do not run the wires together with high­voltage lines or po

wer lines or put them in

the same raceway. This can ca

use
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.
Do not use during the initial transient time
(50ms) after the power supply is switched on.
This sensor is suitable for indoor use only.
A mechanical structure is employed for the

distance adjuster of this product. Take care
not to drop the product.
Do not use this sensor in places having excessive
vapor, dust, etc., or where it may come in direct
contact with water, or corrosive gas.
Take care that the sensor does not come in
direct contact with water, oil, grease, or
organic solvents, such as, thinner, etc.
This sensor cannot be used in an
environment containing inflammable or
explosive gases.
Never disassemble or modify the sensor.

BGS/FGS FUNCTION

6

٨

This sensor incorporates BGS/FGS function.
Select either BGS or FGS function depending
on the positions of the background and sens­ing object. BGS/FGS function can be select­ed by wiring of the sensing mode selection
input (pink / 2), as shown in the figure below.

Note:

When this product is used, be sure to wire the
sensing mode selection input (pink / 2).

STABILITY INDICATOR

8

٨

Since the CX-44غ use a 2-segment
photodiode as its receiving element, and
sensing is done based on the difference in
the incident beam angle of the reflected
beam from the sensing object, the output
and the operation indicator (orange) operate
according to the object distance.
Further, the stability indicator (green) shows
the margin to the setting distance.

DISTANCE ADJUSTMENT

9

٨

Turn the distance adjuster gradually and light­ly with a screwdriver (please arrange sepa­rately). In order to protect itself, the distance
adjuster idles if turned fully.
If the adjuster is idled when distance adjust­ment is done, carry out the adjustment again.

٨

When this product is used, be sure to carry
out the distance adjustment.
Since the distance adjuster of this sensor is a
5-turn adjuster, when the point and is
adjusted as explained in the table below,
there may be more than 1 turn between the
point and .
Therefore, make sure to remember the turns
of both points to find the optimum position.
Be sure to wire the sensing mode selection
input (Pink/2) before distance adjustment. If
the wiring is done after the distance
adjustment, the sensing area is changed.

Distance
adjuster

Step

Place an object at the required
distance from the sensor, turn the
distance adjuster gradually
clockwise, and find out point
where the sensor changes to
the detecting condition.

Remove the object, turn the ad­juster clockwise further until the
sensor goes into the detecting
state again. Once it has entered,
turn the adjuster backward a lit­tle until the sensor returns to the
undetecting condition. That

posi-

tion is designated as point

.
When the sensor does not go in­to the detecting condition even if
the adjuster is fully turned clock­wise, the position where the ad­juster was fully turned is regard­ed as the point .

ԛ

The optimum position to stably
detect objects is the center point
between and .
