This product has been developed / produced for industrial use only.
Make sure that the power supply is off while wiring.
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.
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.
Take care that the sensor is not directly exposed to fluorescent lamp from a rapid-
starter lamp, a high frequency lighting device or sunlight etc., as it may affect the
sensing performance.
Do not use during the initial transient time (200ms) after the power supply is
switched on.
The cable length should be up to 100m.
When connecting the induction load for a load,
such as DC relay, the measure against surge
should be done, as shown in the figure right.
This sensor is suitable for indoor use only.
Do not use this sensor in places having excessive vapor, dust, etc., or where it
may come in contact with water, or corrosive gas.
Take care that the sensor does not come in contact with water, oil, grease, organ-
ic solvents, such as, thinner etc., or strong acid, and alkaline.
The following items are required, as conditions for use in order to conform to CE Marking.
࡮ The output applied voltage should be the same as the supply voltage of the sensor.
࡮Be sure to add a short-circuit protection (a fuse or a breaker) to the power sup-
ply input and the output.

MOUNTING THE SHORT-CIRCUIT METAL
JOINT (VF-SKG)

٨If the sensor and the load are supplied power from the same power supply, the
number of wires can be reduced by one by using the enclosed short-circuit metal
joint.
࡮Loosen the screws on terminals ԙand Ԛ.
Mount the short-circuit metal joint VF-SKG on the
terminals as shown on the right.

To maintain a watertight performance, the cable should have an outer diameter
between Ǿ6 to Ǿ10mm with a smooth covering material that allows the gland to
be securely tightened, however, the tightening torque of the screw should be of
0.96 to 1.44N㨯m.

The model No. with suffix 'T' stands for the timer incorporated models.
The model No. with suffix 'P' shown on the label affixed to the thru-beam type sensor is
the emitter, 'D' shown on the label is the receiver.
(e.g.) Thru-beam type sensor emitter: VF-M10P, Thru-beam type sensor receiver: VF-M10D
The retroreflective type sensor with polarizing filters may not stably detect specular or
glossy objects through transparent film since light is polarized by the transparent film. For
details, refer to ' RETROREFLECTIVE TYPE SENSOR WITH POLARIZING FILTERS'.
The sensing range for the retroreflective type sensor are specified for the RF-230 reflector.
Further, the sensing range is the possible setting range for the reflector. The sensor can
detect an object less than 0.1m (VF-PRM3: 0.2m) away.
The sensing range of the diffuse reflective type sensor is specified for white non-glossy
paper (200200mm) as the object.

ADJUSTMENTS

٨
Adjust the sensitivity, observing the
operation indicator (red). However,
since the condition for lighting up of
the indicator depends on the com-
bination of the sensing condition
and the selected operation Light-
ON / Dark-ON, verify if from the ta-
ble on the light.
For the sensor with timer, be sure to adjust in the state where
the timer function is not operating. As shown in the figure right,
set the timer operation mode switches to '3' and '4' respectively.

Set the operation mode switch to the Light-ON mode position (LIGHT ON side).
Placing the sensor and the reflector face to face along a straight line, move the
reflector in the up, down, left and right
directions, in order to determine the
range of the light received condition
with the help of the operation indicator
(red). Then, set the reflector at the cen-
ter of this range.
Similarly, adjust for up, down, left and
right angular movement of the reflector.
Further, perform the angular adjustment
for the sensor also.

Turn the sensitivity adjuster fully counterclockwise to
the minimum sensing range position, MIN.
Place an object at the required distance from the sen-
sor, turn the sensitivity adjuster gradually clockwise,
and find out point where the sensor changes to the
light received condition.
Remove the object, turn the sensitivity adjuster fur-
ther clockwise, and find out point where the sensor
changes to the light received condition again with on-
ly the background.
When the sensor does not go to the light received
condition even if the adjuster is fully turned clock-
wise, point is this extreme point.
The optimum position to stably detect objects is the
center point between and .

How to mount
SLIT MASK (OPTIONAL)
(Exclusively for thru-beam type sensor)
11
٨With the slit mask (OS-VF-غ), the sensor can detect a small object.
However, the sensing range is reduced when the slit mask is mounted.
࡮Check the directions of the slit mask and press it to the
lens surface till you feel a click.
