MS-N70 (Sensor mounting bracket): 1 set, Gland and gland washer: 1 set
Gland packing (large / small 1 pc. each): 1 set, VF-SKG (Short-circuit metal joint): 1 pc.
RF-230 (Reflector): 1 pc. for the retroreflective type sensor
Accessories
Adjusting screwdriver: 1 pc. for the diffuse reflective type sensor and for sensors with timer functions
2 sets of sensor mounting bracket, gland, gland washer and gland
packing are attached for the thru-beam type sensors.
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
2) 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 '
The sensing range for the retroreflective type sensor are specified for the RF-230 reflector.
3)
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.
4) The sensing range of the diffuse reflective type sensor is specified for white non-glossy
paper (200 200mm) as the object.
2 CAUTIONS
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.

6 MOUNTING THE SHORT-CIRCUIT METAL
JOINT (VF-SKG)
If 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.
