Notes: 1)

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

2) 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, VF2-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.

CAUTIONS

This product has been developed / produced for inductrial use.

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 rapidstarter lamp, a high frequency lighting device or sunlight etc., as it may affect the sensing performance.

Do not use during the initial transient time (VF series: 200ms, VF2 series: 50ms) 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 direct contact with water, or corrosive gas.

Take care that the sensor does not come in direct contact with water, oil, grease, organic solvents, such as, thinner etc., or strong acid, and alkaline.

The following items are required, as conditions for use of VF series in order to conform to CE. ࡮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.

WIRING

To maintain a watertight performance, the cable should have an outer diameter between Ǿ6toǾ10mm 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.

MOUNTING THE SHORT-CIRCUIT METAL JOINT (VF-SKG) (Accessory for VF series)

number of wires can be reduced by one by using the enclosed short-circuit metal joint.

ADJUSTMENTS

٨٨Adjust the sensitivity, observing the

operation indicator (red). However, since the condition for lighting up of the indicator depends on the combination of the sensing condition and the selected operation LightON / Dark-ON, verify if from the table 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.

٨ Beam alignment

Thru-beam type sensor

Set the operation mode switch to the Light-ON mode position (LIGHT ON side).

Placing the emitter and the receiver face to face along a straight line, move the emitter 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 emitter at t he center of this range.

Similarly, adjust for up, down, left and right angular movement of the emitter.

Further, perform the angular adjustment for the receiver also.

Retroreflective type sensor

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 center 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.

٨ Sensitivity adjustment

Diffuse reflective type sensor

Turn the sensitivity adjuster fully counterclockwise to the minimum sensing range position, MIN.

Place an object at the required distance from the sensor, 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 further clockwise, and find out point where the sensor changes to the light received condition again with only the background.

When the sensor does not go to the light received condition even if the adjuster is fully turned clockwise, point is this extreme point.

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

RETROREFLECTIVE TYPE SENSOR

٨ Please take care of the following points

when detecting materials having a gloss.

ԘԙMake L, shown in the diagram, sufficient-

ly long. Install at an angle of 10 to 30 degrees to the sensing object.

* Retroreflective type sensor with polariz-

ing filters do not need the above adjustment.

RETROREFLECTIVE TYPE SENSOR WITH POLARIZING FILTERS

٨ If a shiny object is covered or wrapped with a transparent film, such as those

described below, the retroreflective type sensor with polarizing filters may not be able to detect it. In that case, take the following measures given below.

Make L sufficiently long
